The relation between the volume of the gas and the temperature is established by Charles's law. With a decrease in the temperature, the volume decreases by 45.7 mL. Thus, option c is correct.

Charle's law states the direct relation present between the temperature and the volume of the gas. The law is given as:

V₁ ÷ T₁ = V₂ ÷ T₂

Given,

V₁ = 50 mL

T₁ = 303.15 K

T₂ = 277.15 K

Substituting the value the final volume is calculated as:

50 ÷ 303.15 = V₂ ÷ 277.15

V₂ = (50 × 277.15) ÷ 303.15

= 45.71 mL

Therefore, option c. 45.7 mL is the final volume.

Answer:

¿Cuál será el pH de una disolución saturada de hidróxido de cinc?.

Explanation:

Dato: Kps (Zn(OH)2) = 1,8 x 10-14. Solución: 9,52.

The molar solubility in water of Ag₂CrO₄ is 2.52 * 10⁻⁴ M .

The measure of the degree to which a substance gets dissolved in a solvent to become a solution.

The formula for determination of molar solubity is

[tex]\rm K_{sp} = [A^+]^a [B^-]^b[/tex]

[tex]\rm K_{sp}[/tex]          = solubility product constant

[tex]\rm [A^+]^a[/tex]  =     cation in an aqueous solution

[tex]\rm [B^-]^b[/tex]  = anion in an aqueous solution

a, b          = relative concentrations of a and b

We have the data given as

[tex]\rm K_{sp}[/tex] for Ag₂CrO₄ is 8 x 10⁻¹²

For Silver chromate , the solubility would be only one-half of the Ag⁺ concentration.

We denote the solubility of Ag₂CrO₄ as S mol L⁻¹.

Then for a saturated solution, we have

[Ag⁺]=2S

[CrO₂⁴⁻]=S

the relation between the solubility and the solubility product constant depends on the stoichiometry of the dissolution reaction

(2S)²(S)=4S³ = 8 * 10⁻¹²

S=∛ (2*10⁻¹²)

S= 1.26 * 10⁻⁴ M

2S = 2.52 * 10⁻⁴ M

Therefore the molar solubility in water of Ag₂CrO₄ is 2.52 * 10⁻⁴ M .

Answer:

1) K and Rb

2) 20 protons, 20 neutrons, and 20 electrons.

Explanation:

1) If it's in the same column, it has the same # of valence electrons (e- on the outer shell), therefore similar chemical properties.

2)

1) atomic #, 20, is the number of protons

2) subtract the mass number from # of protons, which you get 20 neutrons

3) Number of electrons in a neutral atom = number of electrons, which is 20. You can also check yourself by looking at electron configuration on a full periodic table.

Explanation:

When a substance goes from a solid to a gas without going through a liquid stage .     Mothballs is an example.

The reaction:

C2H4 + H2 = C2H6

what is the maximum mass of ethane (c2h6) that can be formed?

The amount of hydrogen:

n(H2) = m(H2) / M(H2) = 5.28 / 2 = 2.64 mol

The amount of ethylene:

n(C2H4) = m(C2H4) / M(C2H4) = 9.91 / 28 = 0.354 mol

We see that the hydrogen is an excess reagent

The maximum mas of ethane is:

m(C2H6) = n(C2H4) * M(C2H6) = 0.354 * 30 = 10.62 g

what is the formula for the limiting reagent? - C2H4

what mass of the excess reagent remains after the reaction is complete? grams

The amount of hydrogen after reaction:

n2(H2) = 2.64 - 0.354 = 2.286 mol

m2(H2) = 2.286 * 2 = 4.572 g

Answer: m(C2H6)=10.62 g; C2H4; m2(H2)=4.572 g

Explanation:

So, the formula mass of aluminum chloride is 26.98154+3(35.453)=133.34054 g/mol.

This means that 42.3 grams of aluminum chloride are 42.3/133.34054=0.31723285356426 moles.

From the equation, we know that for every 3 moles of bromine consumed, 2 moles of aluminum chloride are consumed.

This means that (0.31723285356426)(3/2)=0.47584928034639 moles of bromine are needed.

So, the formula mass of a bromine molecule is 2(79.904)=159.808 g/mol, and thus the answer is (159.808)(0.47584928034639), which is about 76.1 g

Answer:

50g of MgO

Explanation:

2Mg +O2 -----------> 2MgO

2moles of Mg needs 1mole of O2 for complete reaction ie

48g/mol of Mg --------- 32g/mol of O2

Xg of Mg --------- 30g of O2

X=45g of Mg

30g of O2 needs 45g of Mg, but only 30g of Mg is available, thus Mg is the limiting reagent.

2mole of Mg produces 2moles of MgO

ie 48g/mol of Mg ---------- 80g/mol of MgO

==> 30g of Mg -------------- Xg of MgO

X= 50g of MgO.

Taking into account the definition of dilution, if you needed to make 100 mL of a 0.2 M fruit drink solution from the 1.0 M fruit drink solution, you need to add more solvent until you get a final volume of 500 mL.

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

1 M× 100 mL= 0.2 M× Vf

Solving:

(1 M× 100 mL)÷ 0.2 M= Vf

500 mL= Vf

In summary, if you needed to make 100 mL of a 0.2 M fruit drink solution from the 1.0 M fruit drink solution, you need to add more solvent until you get a final volume of 500 mL.

The molarity of a solution prepared by dissolving 3.11 grams of NaOH in

enough water to make 300 milliliters of solution is 0. 256 mol/ L

Explanation:

Molarity (M) is the amount of a substance in a given volume of solution. It is otherwise known as the number of moles of solute in a certain amount of solution.

The unit of molarity is mol/L

Molarity = number of moles of solute divided by the volume of the solution\

Molarity = ?

Number of  moles is calculated using :

Mass of the solute = 3.11 grams of NaOH

Molar mass of the solute = Na + O + H

Let's input the atomic numbers of the elements: Na (23) , O (16) , H (1)

Molar mass of NaOH = 23 + 16 + 1 = 40 g/ mol

Number of moles = 3.11 ÷ 40 = 0.077 mol

Volume of the solution is measured in Liters

Let's convert 300 milliters to liters = 300 divided by 1000 = 0.3 Liters

Molarity = 0.077 ÷ 0.3 = 0. 256 mol/ L

Therefore, the Molarity of the solution is 0. 256 mol/ L
