Calculate the mass in grams of 8.35 × 10²² molecules of CBr₄.

Answers

Answer 1

To calculate the mass in grams of 8.35 × 10²² molecules of CBr₄ (carbon tetrabromide), we need to use Avogadro's number to convert the given number of molecules to moles and then use the molar mass of CBr₄ to convert moles to grams.

The molar mass of CBr₄ can be calculated by adding up the atomic masses of carbon (C) and four bromine (Br) atoms. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of bromine is approximately 79.90 g/mol.

Molar mass of CBr₄ = (1 × 12.01 g/mol) + (4 × 79.90 g/mol) = 331.74 g/mol

To convert the number of molecules to moles, we divide the given number of molecules by Avogadro's number (6.022 × 10²³ molecules/mol):

Moles of CBr₄ = (8.35 × 10²² molecules) / (6.022 × 10²³ molecules/mol) = 0.138 mol

Finally, to find the mass in grams, we multiply the number of moles by the molar mass:

Mass of CBr₄ = (0.138 mol) × (331.74 g/mol) = 45.80 g

Therefore, the mass in grams of 8.35 × 10²² molecules of CBr₄ is approximately 45.80 grams.

calculate the molar solubility of baso4 in a 0.250 m solution of nahso4? ka for hso4- = 1.2 x 10-2.

Answers

The required answer for the molar solubility of BaSO4 in a 0.250 M solution of NaHSO4 is 1.05 × 10-5 M.

Explanation: Molar solubility is defined as the number of moles of a solute that can dissolve per liter of solution before the solution becomes saturated. It can be determined by calculating the equilibrium concentration of the solute using the solubility product expression for the given ionic compound, BaSO4. We are given the concentration of NaHSO4 and the acid dissociation constant for HSO4-.

The balanced chemical equation is:BaSO4(s) ↔ Ba2+(aq) + SO42-(aq)We are assuming the solution is dilute and that the ionic strength is low. Therefore, we can simplify the expression for the solubility product to:Ksp = [Ba2+][SO42-]The expression for the acid dissociation constant of HSO4- is:Ka = [H+][SO42-]/[HSO4-]

The first step is to calculate the concentration of HSO4-. We can use the equilibrium expression for the acid dissociation reaction to solve for [HSO4-]:Ka = [H+][SO42-]/[HSO4-]Rearranging the expression and solving for [HSO4-]:[HSO4-] = [H+][SO42-]/Ka[HSO4-] = (0.250 × x)/(1.2 × 10-2)[HSO4-] = 20.8333 × xThe molar solubility of BaSO4 in a 0.250 M solution of NaHSO4 is x. At equilibrium, the concentration of Ba2+ and SO42- are both x. Using the solubility product expression:Ksp = [Ba2+][SO42-]Ksp = x2x = sqrt(Ksp)[BaSO4] = x = sqrt(Ksp) = sqrt(1.1 × 10-10) = 1.05 × 10-5 MTherefore, the molar solubility of BaSO4 in a 0.250 M solution of NaHSO4 is 1.05 × 10-5 M.

is mixing colored light (like using this equipment in this lab) the same as mixing colored paint (as if you were mixing actual paint together)?

Answers

The mixing of colored light and colored paint follows different color models and produces different outcomes due to the properties of light and pigments.

Mixing colored light and mixing colored paint are not the same. When mixing colored light, such as using equipment in a lab, the primary colors are red, green, and blue (RGB). By combining different intensities of these colors, you can create various shades and hues. Mixing all three primary colors at full intensity produces white light.

On the other hand, mixing colored paint involves using the subtractive color model. The primary colors are cyan, magenta, and yellow (CMY). When you mix paints, the pigments absorb certain wavelengths of light, and the reflected light determines the perceived color. Mixing all three primary colors in paint results in a dark, muddy color, not white.

place the following in order of increasing standard molar entropy. n2o4 (g) no (g) no2 (g)

Answers

The standard molar entropy of no₂ is 240.0 J/(mol.K).Therefore, the order of increasing standard molar entropy of the given gases is n₂o₄ (g) < no (g) < no₂ (g).

Entropy is the measure of disorder in a system. It is a thermodynamic property that depends on the degree of randomness in the molecules of a substance. The unit of entropy is Joules per Kelvin. In general, the entropy of a substance increases with an increase in temperature.

This is because at higher temperatures, the molecules of a substance have more kinetic energy and can move more freely, leading to an increase in the number of possible arrangements of molecules, which increases entropy.

Increasing Standard Molar Entropy Order n₂o₄ (g) < no (g) < no₂ (g)The standard molar entropy (S°) is the entropy of one mole of a substance at standard temperature and pressure (STP). In the order of increasing standard molar entropy, the gases listed are as follows: n₂o₄ (g) has the least entropy because it is a relatively heavy and rigid molecule. It has fewer possible arrangements of molecules, which results in a lower entropy.

The standard molar entropy of n₂o₄ is 304.3 J/(mol.K).no (g) has more entropy than n₂o₄ because it is a lighter molecule that is more mobile. It has more possible arrangements of molecules, leading to higher entropy.

The standard molar entropy of no is 210.6 J/(mol.K).no₂ (g) has the highest entropy because it is the lightest and most mobile molecule of the three gases. It has the most possible arrangements of molecules, leading to the highest entropy. The standard molar entropy of no₂ is 240.0 J/(mol.K).

Therefore, the order of increasing standard molar entropy of the given gases is n₂o₄ (g) < no (g) < no₂ (g).

Which of the following usually occurs when a molecule dissolves in water?
a. The covalent bonds in the molecule break.
b. The covalent bonds in water break.
c. Covalent bonds between the molecule and water form.
d. Covalent bonds between several of the molecules form.
e. Hydrogen bonds form between the molecule and water.

Answers

Answer:

e. Hydrogen bonds form between the molecule and water.

Explanation:

When a molecule dissolves in water, it is typically because the molecule has polar or charged regions that can interact with the polar water molecules. Water is a highly polar molecule due to its bent shape and the presence of electronegative oxygen atoms. As a result, it forms hydrogen bonds with other water molecules and with other polar or charged substances.

When a molecule dissolves in water, the water molecules surround the individual molecules and interact with them through hydrogen bonding. The positively charged hydrogen atoms of water form hydrogen bonds with negatively charged regions of the dissolved molecule, such as oxygen or nitrogen atoms, or with partially negative regions due to uneven distribution of electron density. This interaction between the water molecules and the dissolved molecule is what allows the molecule to become dispersed and solvated in the water, forming a homogeneous mixture.

It's important to note that during the dissolution process, the covalent bonds within both the water molecules and the dissolved molecule generally remain intact. Dissolving in water does not typically involve breaking the covalent bonds within the molecule or the water molecule. Instead, it involves the formation of hydrogen bonds between the solvent (water) and solute (dissolved molecule).

T/F A reaction which is endothermic and has an overall increase in entropy is spontaneous only at high T

"A reaction which is endothermic and has an overall increase in entropy is spontaneous only at high T" is incorrect.

"A reaction which is endothermic and has an overall increase in entropy is spontaneous only at high T" is false.A spontaneous process occurs naturally and without any assistance. The rate of the process does not affect its spontaneity; instead, spontaneity is determined by the change in free energy that occurs during the reaction.A reaction is spontaneous if the Gibbs free energy of the reaction is negative (∆G < 0). Gibbs free energy is calculated using the equation: ∆G = ∆H - T∆S, where ∆H is the enthalpy change, T is the temperature, and ∆S is the entropy change of the reaction.A reaction that is endothermic (∆H > 0) and has an increase in entropy (∆S > 0) can be spontaneous at any temperature if the free energy change is negative.

27 which statement about members of a homologous series is true ? a) they are all constitutional isomers. b) they are always hydrocarbons. c) each differs from its nearest neighbors by 14 amu. d) they may also be classified as tautomers.

Answers

The statement about members of a homologous series that is true is that they differ from their nearest neighbors by 14 amu (c).

A homologous series is a group of compounds with a similar general formula, chemical properties, and a constant increment in molecular structure. As a result, each member varies from the previous by a constant unit, which is often a CH2 group.Each member of the homologous series is classified as either a tautomer or a constitutional isomer. Constitutional isomers, also known as structural isomers, are compounds with the same molecular formula but different structural arrangements. Isomers of tautomers are structural isomers that interconvert by a simple chemical reaction. As a result, the formula and composition of tautomers are the same, but they differ in the distribution of their valence electrons and bonding patterns.Members of a homologous series may or may not be hydrocarbons, and they are not always constitutional isomers. Therefore, statement (a) and statement (b) are both incorrect. Statement (d) is also incorrect because tautomers cannot be classified as members of a homologous series. However, statement (c) is correct because members of a homologous series differ from their nearest neighbors by a constant increment in molecular structure, which is usually 14 amu. Therefore, the correct answer is C.

Answers

If a sample of gas has a volume of 2.50 L at 236 kPa and 75.0 °C, the pressure 1.18 atm is required.

Only ideal gas is subject to the ideal gas law; vanderwaal gas is not. Here, Boyle's and Charles' gas laws are combined. As a result, the new gas pressure is 1.18 atm.

The relation between Pressure, volume, and temperature can be given as:

PV = nRT

In which:

P = pressure of  gas

V= volume of gas

n =number of moles of gas

T =temperature of gas

R = Gas constant

= 0.0821 L.atm/K.mol

Combining Boyle's and Charles' gas law

P₁V₁/T₁ = P₂V₂/T₂

{ (5.28atm) (2.50 L)} ÷348 K ={ (P2) (3.75 L)} ÷298 K

P₂ =1.18 atm

Thus, the new pressure of gas is 1.18 atm when the temperature is changed to 348K and volume is increased to 3.75 L.

2. sublimation, followed by deposition

Following the dashed line at 1 atm of pressure on the phase diagram from 100 to 500 °C, the phase changes that will occur are sublimation, followed by deposition.

At lower temperatures, the substance will undergo sublimation, transitioning directly from the solid phase to the gas phase. As the temperature increases, the substance will exist as a gas.

However, at higher temperatures, as the temperature decreases again, the gas will undergo deposition, transitioning directly from the gas phase back to the solid phase.

The correct statement (e) captures the fundamental principle of the second law of thermodynamics, emphasizing the tendency of entropy to increase in spontaneous processes, leading to a positive net entropy change of the universe.

The second law of thermodynamics is a fundamental principle that describes the behavior of energy and entropy in physical systems. It can be stated in various ways, but the correct statement corresponding to the second law is: In any spontaneous process, ΔS universe - ΔS system + ΔS surroundings > 0.

This statement captures the essence of the second law, which is that the entropy of an isolated system tends to increase over time. The entropy change of the universe (ΔS universe) is the net change in entropy of the system and its surroundings. For a spontaneous process, where the system undergoes a change without external intervention, the total entropy change of the universe must be greater than zero.

The entropy change of the system (ΔS system) and the entropy change of the surroundings (ΔS surroundings) may have opposite signs, but their magnitudes must be such that the net entropy change of the universe is positive. This reflects the irreversibility of natural processes, where entropy tends to increase and energy becomes more dispersed. The correct statement (e) captures the fundamental principle of the second law of thermodynamics, emphasizing the tendency of entropy to increase in spontaneous processes, leading to a positive net entropy change of the universe.
