The highest lattice energy among the given compounds is for MgO. The increasing order of lattice energy for these compounds is NaBr <NaCl< CaCl₂ < MgO.

What is lattice energy?

Lattice energy of a compound is the energy required to convert one mole of the compound into its constituent ions in gaseous states. Lattice energy increases with decrease in size and increase in charge.

Thus, compound containing smaller ions with higher charges are having greater  lattice energy. Both Mg and oxygen are smaller in size and have  charges of +2 and -2 respectively. Na and Ca are bigger than Mg.

Ca2+ is smaller and greater in charge than Na+. Among NaCl and NaBr, Cl is smaller compared to Br thus NaCl has higher lattice energy.

Therefore, the increasing order of lattice energy is NaBr <NaCl< CaCl₂ < MgO.

a compound composed of 3.3% h, 19.3% c, and 77.4% o has a molar mass of approximately 60 g/mol. what is the molecular formula of the compound?

Answers

The molecular formula of the compound would be [tex]H_2CO_3[/tex].

Molecular formula

The molecular formula of compounds is related to their empirical formula, such that:

[Empirical formula]n = Molecular formula

Where n is the ratio of the molar mass of the molecular formula and the molar mass of the empirical formula.

Now, let's find the empirical formula of the compound:

H = 3.3            C = 19.3            O = 77.4

The moles equivalent of each atom can be calculated by dividing by their molar weights.

H = 3.3/1 = 3.3 mol

C = 19.3/12 = 1.6 mol

O = 77.4/16 = 4.8

Dividing through by the smallest mole:

H = 3.3/1.6 = 2.1

C = 1.6/1.6 = 1.0

O = 4.8/1.6 = 3.0

Thus, the empirical formula of the compound is [tex]H_2CO_3[/tex].

Molar mass of the empirical formula = 2+12+48 = 62 g/mol

Molar mass of the molecular formula = 60 g/mol

n = 62/60 = 1.

In other words, the molecular formula of the compound is the same as the empirical formula,  [tex]H_2CO_3[/tex].

Gel electrophoresis is used to separate combinations of DNA, RNA, or proteins based on their molecular sizes. In gel electrophoresis, the molecules that need to be separated are forced through a gel that has tiny pores by an electrical field.

The speed at which the molecules move through the pores in the gel is inversely proportional to their size. This indicates that a smaller molecule will move through the gel further than a larger the molecule.

Describe what happens to the freezing point when tin is added.​

Answers

Answer:

The freezing point of a substance is the temperature at which it changes from a liquid to a solid. When tin is added to a substance, it can lower the freezing point of the substance. This is known as a colligative property of matter, which refers to the ability of certain substances, such as solutes, to alter the physical properties of a solvent (such as the freezing point or boiling point) without changing the chemical composition of the solvent.

In the case of tin, when it is dissolved in a solvent, it can disrupt the interactions between the solvent molecules, making it more difficult for the solvent to form a solid. As a result, the freezing point of the solvent is lowered. This effect is more pronounced when the concentration of the solute is higher.

It's important to note that the freezing point depression caused by tin (or any other solute) is dependent on the concentration of the solute and the nature of the solvent. Different solvents will have different freezing points, and the freezing point depression caused by a given solute may vary depending on the solvent used.

Answers

Formula to determine Ph after Titration: pOH = -log(OH).

The pH of the solution after the addition of 300.0 ml of HBr is 1.6.

What is a Titration?

Titration is a popular laboratory technique for quantitative chemical analysis to calculate the concentration of an identified analyte (also known as titrimetry and volumetric analysis) (a substance to be analyzed). A standard solution with a known concentration and volume is created as the reagent, also known as the titrant or titrator. To ascertain the concentration of the analyte, the titrant reacts with a solution of the analyte (also known as the titrant). The titration volume is the amount of titrant that interacted with the analyte.

Now;

Conc of Ca, pH of the solution before the addition of any HBr. :

pOH = -log(OH)

[OH-] = 2*[Ca(OH)2] = 2*(0.1) = 0.2 M

pOH = -log(0.2) = 0.698

pH = 14-0.698

pH = 13.3

pH of the solution after the addition of 300.0 mL HBr:

mmol of OH- = 2*MV = 2*100*0.1 = 20 mmol of OH-

mmol of H+ = MV = 0.1*V = 0.1*300= 30 mmol of HBr

left ion = 30-20 = 10 mmol of OH-

V = 100+300 = 400 mL

[H+] = 10/400 = 0.025 M

pH= -log(0.025 ) = 1.6

What is percentage yield?

Recovery is the ratio of actual recovery to theoretical recovery. It is calculated by dividing the experimental yield by the theoretical yield and multiplying by 100%. If the actual and theoretical yields are equal, the yield rate is 100%. Yields are usually less than 100% because actual yields are often lower than theoretical. This may be due to incomplete or competing reactions and sample loss during recovery. Recoveries can exceed 100%. This means that more samples were recovered from the reaction than expected. This can occur when other reactions that form the product occur. Another potential source of error is overage caused by incomplete removal of moisture or other contaminants from the sample. Yield is always positive.

The angle relative to the normal interface of the two liquids at which the light is totally reflected is 78 degrees.

What is Snell's law?

The incident rays' landing point and the angle it forms with the refracted ray—not to mention the normal line that is dropped on the plane perpendicularly—create the point of refraction. In contrast to reflection, the medium through which the light rays are flowing produces a significant change in refraction. The refractive indices highlight Snell's Law's dependence on the medium.

Snell's Law, also referred to as the Law of Refraction, is an equation that connects the angles of incident and transmitted light at the meeting point of two dissimilar media. All materials and phases of matter are subject to Snell's Law.

the refractive index of the ethyl alcohol =1.361

the refractive index of the water =1.333

According to Snell's Law of refraction;

What is electromotive force?

Energy transfer to an electric circuit per unit of electric charge measured in volts is called electromotive force .

Given, Voltage= 1.5 Volts

Internal resistance A  is 0.240 Ohms

Internal resistance B is 0.180 Ohms

and current = 600 mA = 0.6 Amps

a. To find resistance of the bulb:

The total electromotive force (E) of the electric circuit:

E = 2*1.5

= 3.0 Volts

Total internal resistance = 0.240 + 0.180 = 0.42 ohms

Electromotive force (E) is given by the formula:

E= V+ I r

E is electromotive force

V is  voltage and I is the current.

r is internal resistance.

Ohm's law is given by:

V= I R

Answers

18.0121 grams of CH₃OH must be added to water to prepare 225ml of a solution that is 2.5 m CH₃OH.

Molarity of the solution is defined as the number moles of the solute present in one liter of the solution. Molarity is calculated from the equation,

M = No. of moles of solute / Volume of the solution in terms of liter.

Volume of solution given is 225 ml. As molarity is expressed in moles per liter.

Volume of solution = 0.225 L

Calculate the mole of CH₃OH by the expression of molarity,

225ml × 2.5 mole/1000 ml = 0.562 moles of CH₃OH .

Now convert 0.175 moles by multiplying molar mass of the solution. So,

Assuming that no new water molecules entered the glass while the water was freezing, would you say that frozen water (ice) takes up more space than liquid water, less space, or about the same?

Answers

Answer:

Frozen water(ice) indeed takes up a larger volume than water in liquid state.

Explanation:

This is because when water liquid turns into a solid, energy is absorbed hence it gets cooler, the bonds are strengthen and expands to its maximum.

this means that the structure changes when water turns to ice, from the semi random arrange in liquid state to lattice in ice. this expansion between the molecules have alot of space between it, the molecules are less compact.

Since the molecules are less compact, ice is therefore less dense than water, hence it floats on water and not sink.

And this almost means that ice increases in volume by approximately 9% than its initial liquid water.
