Question

1. write the chemical equation for the synthesis of ammonia (nh₃) from nitrogen and hydrogen. both hydrogen and nitrogen are diatomic elements

Explanation:

Step1: Identify reactants and products

Reactants: Nitrogen ($\ce{N2}$) and Hydrogen ($\ce{H2}$) (both diatomic). Product: Ammonia ($\ce{NH3}$).

Step2: Write unbalanced equation

$\ce{N2 + H2 -> NH3}$

Step3: Balance the equation

Balance N: 2 N on left, so 2 $\ce{NH3}$ on right: $\ce{N2 + H2 -> 2NH3}$
Balance H: 6 H on right (2×3), so 3 $\ce{H2}$ on left: $\ce{N2 + 3H2 -> 2NH3}$
Check: 2 N, 6 H on both sides. Also, note the reaction conditions (usually high temp, pressure, catalyst) but the basic equation is as above.

Answer:

The chemical equation for the synthesis of ammonia is $\ce{N2 + 3H2 <=>[\text{High Temperature, Pressure, Catalyst}] 2NH3}$ (the equilibrium arrow is used as it's a reversible reaction under typical conditions; if just the balanced equation without conditions is acceptable, $\ce{N2 + 3H2 -> 2NH3}$ is also correct, but the reversible form with conditions is more accurate for the Haber process).
