Calculating the mass of water formed from the combustion of hydrogen in the presence of excess oxygen
Explanation: When hydrogen burns in the presence of excess oxygen, it undergoes combustion to form water. The balanced chemical equation shows that 2 molecules of hydrogen react with 1 molecule of oxygen to form 2 molecules of water. The molar mass of hydrogen and water is calculated, and the given mass of hydrogen is converted to moles. The limiting reactant is determined, and the number of moles of water formed is calculated using stoichiometry. Finally, the mass of water formed is calculated by multiplying the number of moles of water by its molar mass.
- Write the balanced chemical equation for the reaction:
2H2 + O2 → 2H2O
This equation shows that two molecules of hydrogen react with one molecule of oxygen to form two molecules of water. - Calculate the molar mass of hydrogen and water:
Molar mass of hydrogen (H2) = 2 x atomic mass of hydrogen (1.008 g/mol) = 2.016 g/mol
Molar mass of water (H2O) = atomic mass of hydrogen (1.008 g/mol) + atomic mass of oxygen (15.999 g/mol) = 18.015 g/mol - Convert the given mass of hydrogen to moles:
10 g H2 x 1 mol/2.016 g = 4.96 mol H2 - Determine the limiting reactant:
Since there is excess oxygen present, the limiting reactant is hydrogen as it is completely consumed in the reaction. - Calculate the number of moles of water formed:
From the balanced equation, 2 moles of H2 produces 2 moles of H2O
So, 4.96 moles of H2 will produce 4.96 moles of H2O - Calculate the mass of water formed:
Mass of water = number of moles of water x molar mass of water
= 4.96 mol x 18.015 g/mol
= 89.3 g
Therefore, the mass of water formed from the combustion of 10 g of hydrogen in the presence of excess oxygen is 89.3 g.
