Solid lithium metal and diatomic nitrogen gas react spontaneously to form a solid product. Give the balanced chemical equation (
skad [1K]

Answer:

6 Li(s) + N₂(g) → 2 Li₃N(s)

Explanation:

Solid lithium metal and diatomic nitrogen gas react spontaneously to form a solid product (lithium nitride). The chemical equation is:

Li(s) + N₂(g) → Li₃N(s)

Since the atomicities in the product are odd, the easiest way to balance the equation is by first multiplying it by 2.

Li(s) + N₂(g) → 2 Li₃N(s)

The final (balanced) equation is:

6 Li(s) + N₂(g) → 2 Li₃N(s)

The gram formula mass of NH4Cl is(1) 22.4 g/mole (3) 53.5 g/mole(2) 28.0 g/mole (4) 95.5 g/mole
g100num [7]
The answer is (3) 53.5 g/mol. The gram formula mass means that the mass of one mol compound. 1N=14, 4H=4, 1Cl=35.5. So the gram formula mass of NH4Cl=14+4+35.5=53.5 g/mol.
