Question

Balance chemical equation
1 when copper is heated in air
2 Nitrogen react with hydrogen to from ammo

Answer 1

Balanced Equation:

1) When Copper is heated in air.

2Cu + O2 >>>>> 2CuO

When 2 moles of Copper is heated in air(Oxygen), it gives 2 moles if Copper Oxide

2) N2 + 3H2 >>>> 2NH3

When Nitrogen gas reacts with 3 moles of Hydrogen gas, it yields 2 moles of Ammonia
