Answer:

1.53 L

Explanation:

Step 1: Given data

  • Mass of oxygen (m): 11.2 g
  • Pressure (P): 7.78 atm
  • Temperature (T): 415 K
  • Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Calculate the moles (n) corresponding to 11.2 g of oxygen

The molar mass of oxygen is 32.00 g/mol.

11.2 g × (1 mol/32.00 g) = 0.350 mol

Step 3: Calculate the volume of oxygen

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 0.350 mol × (0.0821 atm.L/mol.K) × 415 K / 7.78 atm

V = 1.53 L

Hydrogen peroxide, H2O2, decomposes according to the equation above. This reaction is thermodynamically favorable at room temper
s2008m [1.1K]

Answer:

4H₂O₂ → 4H₂O + 2O₂

Explanation:

The chemical reaction for the decomposition of hydrogen peroxide can be represented as follows;

2H₂O₂ → 2H₂O + O₂

Therefore, two molecules of hydrogen peroxide decomposes into two molecules of water and one molecule of oxygen.

In a related diagram, we have 4 molecules of hydrogen peroxide decomposing, therefore we have;

4H₂O₂ → 4H₂O + 2O₂

The attached diagram shows the products of the decomposition of the four molecules of hydrogen peroxide.
