Answer:
Explanation:
The balanced chemical equation for this reaction is given as:
3 PbO + 2 NH_3 -> 3 Pb + N_2 + 3 H_2O
Thus, 3 moles of lead oxide react with 2 moles of ammonia to generate 3 moles of lead, 1 mole of nitrogen gas and 3 moles of water.
Molar mass of lead oxide = 207.2 + 16 = 223.2 gm/mole
Molar mass of ammonia = 14 + 3 x 1 = 17...
