The reaction for combustion of hydrogen gas in the oxygen is as follows:
Here, oxygen is present in excess thus, hydrogen will be limiting reactant.
2 moles of hydrogen gives 2 moles of water vapor, thus, 1 mole will give 1 mole of water vapor.
The mass of hydrogen is 1.80 g and molar mass of is 2 g/mol converting mass into number of moles:
Thus, 0.9 mol of gives 0.9 mol of
. Molar mass of
is 18 g/mol, converting number of moles to mass,
m=n×M=0.9 mol× 18 g/mol=16.2 g
Therefore, mass of water vapor produced will be 16.2 g.
Answer: 6.71 g
Explanation:
Limiting reagent is the reagent which limits the formation of product. Excess reagent is one which is in excess and thus remains unreacted.
Thus lithium is the limiting reagent and nitrogen is the excess reagent.
As can be seen from the balanced chemical equation, 6 moles of lithium reacts with 1 mole of nitrogen to give 2 moles of lithium nitride.
Thus 0.578 moles of lithium react with 0.096 moles of nitrogen.
6 moles of lithium give = 2 moles of lithium nitride
Thus 0.578 moles of lithium give= of lithium nitride.
Mass of lithium nitride
Mass of lithium nitride=
