Question

Q) write balanced molecular equations for the following word equations but make it more informative:
(i) carbon dioxide + carbon = carbon monoxide
(ii) silver oxide = silver + oxygen
(iii) phosphorus pentoxide = potassium chloride + oxygen
(iv) aluminum + oxygen = aluminum oxide
(v) potassium chlorate = potassium chloride + oxygen ​

Answer 1

Answer:

1. CO2(g) + C(s) --- 2CO(g)

2. Ag2O(s) --- 2Ag(s) + 1/2O2(g)

3. P2O5(s) --- 2P(s)+ 5/2O2(g)

4. 2Al(s) + 3/2O2(g) --- Al2O3(s)

5. KClO3(s) --- KCl(s) + 3/2O2(g)

Explanation:

1. Write the correct formula for any compound, by following valency number.

2. Balance no. of each element on both side of reaction.

3. Use fractional stoichiometric coefficient, when needed for avoiding lengthier balancing.

4. Mention physical state for every component of reaction.
