The disinfectant hydrogen peroxide (H2O2)

Chemistry
1 answer:
Blababa [14]3 years ago
4 0

Answer:

1.1 mol of O2

Explanation:

First we need the balance chemical equation which is

2 H2O2 -------> 2 H2O + O2

This is important because in stoichiometry you can go from units of one thing to other by using mole ratios, here the mole ratio is 2 mol of H2O2  for one mole of O2.

2.2 mol H2O2 \frac{1mol O2}{2 mol H2O2} = 1.1 mol of O2

The following two reactions are important in the blast furnace production of iron metal from iron ore (Fe2O3):2C(s) + O2(g) -&gt
Inga [223]

Answer: A) 67.1 moles

Explanation:

The balanced reaction is :

2C(s)+O_2(g)\rightarrow 2CO(g)

Fe_2O_3+3CO(g)\rightarrow 2Fe+3CO_2

To calculate the moles, we use the equation:

\text{Number of moles of iron}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{5.00\times 1000g}{56g/mol}=89.3moles

According to stoichiometry;

2 moles of iron is produced by 3 moles of carbon monoxide

89.3 moles of iron is produced by=\frac{3}{2}\times 89.3=134 moles of carbon monoxide

2 moles of carbon monoxide is produced by = 1 mole of oxygen

Thus 134 moles of carbon monoxide is produced by = \frac{1}{2}\times 134=67.1 moles of oxygen
