Name the reactants and products in the following skeletal equations and balance them.
(1) Na + Cl2 - NaCl
(ii) N2 + H2 - NH3
(iii) Na + O2 - Na2O
(iv) Fe + H2O - Fe3O4 +H
(v) Na + HO - NAOH+H2
Answers
Given : Balancing and reactants of given equations.
Explanation:
1. 2Na + {Cl}2 - 2NaCl
Reactant : Sodium and chlorine .
Product : sodium chloride .
2 .{N} 2 +3{H}2 - 2{NH}3
Reactant : Nitrogen and hydrogen.
Product : ammonia.
3. 4{Na} +{O}2 - 2 {Na}2O
Reactant : sodium and oxygen.
Product : Sodium oxide.
4. 3 {Fe} +4{ H_2_O} - { Fe _3_O_4 } + 8 {H}
Reactant : Iron and water.
Product : Iron oxide and hydrogen.
5. Since the question should be though it's an
oxidation - reduction reaction so the answer
should be ;
2{Na} + 2{H_2_O} - 2{NaOH} + {H}2
Reactant :sodium and water.
Product: Sodium hydroxide and hydrogen.
