Question

2 Name the reactants and products in the following skeletal equations and balance them.
(ii) N2 + H2 → NH3
(iii) Na + O2 → Na20
(iv) Fe + H2O → Fe2O4 + H2
(v) Na + H2O + NaOH + H2
(i) Na + Cl2 → NaCl​

Answer 1

Explanation:

(ii) nitrogen+hydrogen=nitrate

(iii) sodium+ oxygen=sodium oxide

(iv) Ferrous+water=ferrous oxide+hydrogen

(v) sodium+water= sodium hydroxide+ hydrogen

(I) sodium+ chlorine= sodium chloride

Answer 2

Answer:

Ans 1 : nitrogen + oxygen = Ammonia

balance : N2 + 3H2 = 2NH3.

equation.

Ans 2 : sodium + oxygen = sodium oxide

balance : 4Na + O2 = 2Na2O.

equation.

Ans 3 : iron + water = iron oxide + hydrogen

balance : 3Fe + 4H2O = Fe3O4 + 4H2

equation .

Ans4 : sodium + water = sodium hydroxide + hydrogen

balance : 2Na + 2H2O = 2NaOH + H2.

equation.

Ans 5 : sodium + chlorine = sodium chloride (basic salt)

balance : 2Na + Cl2 = 2NaCl.
