<h3>What is a Double Dispalcement Reaction?</h3>

The reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.

Many double displacement reactions occur between ionic compounds that are dissolved in water.

In a double displacement reaction, atoms from two different compounds switch places.

The reactants are two compounds and the products are two different compounds.

The reaction given below is an example of Double Dispalcement Reaction

CaCO₃ + Ag₂SO₄ → CaSO₄ + Ag₂CO₃

1 mole of Calcium Carbonate reacts with Silver Sulfate to form 1 mole of Calcium Sulfate and Silver Carbonate , CaSO₄ + Ag₂CO₃.

2Al+3Cl2⟶2AlCl3

Leviafan [203]

Answer:

7.335 moles of Cl₂ are required to react with 4.89 miles of Al.

Explanation:

Given data:

Moles of Al = 4.89 mol

Number of moles of Cl₂ required = ?

Solution:

Chemical equation:

2Al + 3Cl₂ → 2AlCl₃

Now we will compare the moles of Al and chlorine from balance chemical equation.

Al : Cl₂

2 : 3

4.89 : 3/2×4.89 =7.335 mol

Thus, 7.335 moles of Cl₂ are required to react with 4.89 miles of Al.

A self-contained underwater breathing apparatus (SCUBA) uses canisters containing potassium superoxide. The superoxide consumes

emmainna [20.7K]

Answer:

52.0004 grams of mass of potassium superoxide is required

Explanation:

Let moles carbon dioxide gas be n at 22.0 °C and 767 mm Hg occupying 8.90 L of volume.

Pressure of the gas,P = 767 mm Hg = 0.9971 atm

Temperature of the gas,T = 22.0 °C = 295.15 K

Using an ideal gas equation to calculate the number of moles.

$PV=nRT$

$n=\frac{0.9971 atm\times 8.90 L}{0.0821 atm L/mol K\times 295.15 K}$

n = 0.3662 mol

$4KO_2(s)+2CO_2(g)\rightarrow 2K_2CO_3(s)+3O_2(g)$

According to reaction, 2 moles of carbon-dioxide reacts with 4 moles of potassium superoxide.

Then 0.3662 mol of of carbon-dioxide will react with:

$\frac{4}{2}\times 0.3662 mol=0.7324 mol$ of potassium superoxide.

Mass of 0.7324 mol potassium superoxide:

0.7324 mol × 71 g/mol = 52.0004 g

52.0004 grams of mass of potassium superoxide is required.
