how many kg of solvent would contain 130 grams of ZnBr2 if the solution was 0.950 grams

Answers

Answer:

0.00731 kg

Explanation:

Given that solution is a product of solute and solvent.

Hence, solution = solute * solvent

In this case, the solution is given as 0.950 grams = 0.00095 kilograms

solute is given as 130 grams = 0.13 kilograms

Hence to get the amount of solvent in kilograms, we have

Solution ÷ Solute => 0.00095 ÷ 0.13

= 0.0073076923

=> 0.00731 kilograms

Answers

0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.

What is an ideal gas equation?

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.

According to Ideal Gas Equation,

PV = nRT

Therefore, P ∝ T

P₁T₂ = P₂T₁

Given :

P₁ = ?

P₂ = 1.11 atm

T₁ = 30.0 C

T₂ = 15 C

Solving :

P₁ x 30 = 1.11 x 15

P₂ = 0.555 atm

Hence, 0.555 atm is the pressure of a fixed volume of a gas at 30.0C if it has a pressure of 1.11atm at 15C.

Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?

Answers

Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Which mass is made up of 6.02x10^23 atoms? none of these 23 g sodium 42 g krypton 24 g carbon 78 g potassium

Answers

Answer:

23 g sodium

Explanation:

In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).

According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23

Using the formula; mole = mass/molar mass

- Sodium = 23g/23g/mol = 1mol

- Krypton = 42g/84g/mol = 0.5mol

- Carbon = 24g/12g/mol = 2mol

- Pottasium = 78g/39g/mol = 2mol

Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

A compound consists of 14.6% carbon and 85.4% chlorine by mass. What is its empirical formula?

Answers

Answer:

[tex]CCl_{2}[/tex]

Explanation:

When calculating an empirical formula from percentages, assume you have a 100g sample. This allows you to convert the percentages directly to grams, because X % of 100g is X grams.

So:

14.6% C = 14.6g C, 85.4%Cl = 85.4g Cl

The next step is to divide each mass by their molar mass to convert your grams to moles.

14.6g/12.01 = 1.22 mol

85.4g/35.45= 2.41 mol

Then you will divide all of your mol values by the SMALLEST number of moles. This gives you whole numbers that are the mole ratio (subscripts) of the empirical formula.

1.22 mol/1.22 mol = 1

2.41 mol/1.22 mol = 2

So the empirical formula is

[tex]CCl_{2}[/tex]

The empirical formula of the compound is CCl2.

HOW IS EMPIRICAL FORMULA CALCULATED:

Empirical formula of a compound is the smallest ratio of elements contained in that compound. The steps for calculating the empirical formula are as follows:

14.6% carbon and 85.4% chlorine by mass means the compound has 14.6g of C and 85.4g of Cl

First, we divide each mass by their respective molar mass:

C = 14.6g ÷ 12g/mol = 1.22mol

Cl = 85.4g ÷ 35.5g/mol = 2.41mol

Next, we divide each mole value by the smallest value:

C = 1.22mol ÷ 1.22 = 1

Cl = 2.41mol ÷ 1.22 = 1.97

Approximately, the carbon to chlorine ratio is 1:2, hence, the empirical formula of the compound is CCl2.

HELP ASAP PLEASE 2H2+ O2 =2H2O, how many moles of water is produced if there is 10gm of O2 gas used?

= (10^-2 / 32) x 2 = 6.25 x 10^-4 moles H2O

What is the mass of 8.98 x 10^24 particles of CaCl2?

Answers

Answer:

1656.12grams

Explanation:

To calculate the mass of a substance in a particle, we need to calculate the number of moles (n).

n = nA × 6.02 × 10^23

nA = 8.98 x 10^24 particles

number of moles = 8.98 x 10^24 ÷ 6.02 × 10^23

n = 8.98/6.02 × 10^ (24 - 23)

n = 1.492 × 10^1

n = 14.92moles of CaCl2

Molar Mass of CaCl2 where Ca = 40g/mol, Cl = 35.5g/mol

CaCl2 = 40 + 35.5(2)

= 40 + 71

= 111g/mol

Using mole = mass/molar mass

mass = molar mass × mole

mass = 111 × 14.92

mass = 1656.12grams.

if you had to explain to a friend how to balance a chemical equation, what
would you say to them?

Answers

Answer:

make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.

Explanation:

A chemical reaction can be balanced by multiplying each side with suitable integers such  that the number of each element in the reaction must be equal number on both side.

What is a balanced chemical equation?

According to the law of conservation of mass for  a chemical reaction, the total mass in the reactant side is equal to the total mass in the product side. Thus, a balanced chemical equation represents the perfect stoichiometry for each reactants and products.

The number of each elements in both side have to be equal in number. If they are unequal on both side, we can balance the reaction by multiplying with suitable integers.

Lets have one example. Consider the given reaction.

[tex]\rm CH_{4} + O_{2} \rightarrow H_{2}O + CO_{2}[/tex]

Here, 4 H are in left side and only 2 in right side. Similarly number of oxygen also not balanced.

The balanced equation requires a coefficient of 2 for water and 2 for oxygen in reactant thus, it can be written as:

[tex]\rm CH_{4} + 2O_{2} \rightarrow 2H_{2}O + CO_{2}[/tex]
