Write and balance the equation for the combination of ammonia gas with solid copper (ii) oxide to produce copper metal, nitrogen gas, and liquid water. what are the states of matter of each element/compound of the equation?

Explanation :

The balanced chemical reaction will be,

By the stiochiometry, 3 moles of solid copper(II)oxide react with 2 moles of ammonia gas to give 3 moles of copper metal, 1 mole of nitrogen gas and 3 moles of liquid water.

The states of matter of each elements and compound is,

Copper(II)oxide is in solid state

Ammonia is in gaseous state

Copper metal is in solid state

Nitrogen is in gaseous state

Water is in liquid state

thats how its supposed to be
