Question

D. Write word equations for the following reactions. Also identify reactants and products in
each reaction.
1. Adding a small amount of dilute hydrochloric acid to sodium carbonate
2. Burning magnesium in air
3. Adding water to quicklime (calcium oxide)
4. Adding a solution of silver nitrate to a solution of sodium chloride
5. Reacting ammonia gas with hydrogen chloride gas
6. Passing hydrogen gas through molten sulphur
E. Answer the following in short.​

Answer 1

Answer:

All the chemical reactions are:-

Explanation:

1. dil2HCl + Na2Co3 ----> 2NaCl+CO2+H2O

2. 2Mg(s) + O2(g) -----> 2MgO

3. H2O(l)+ CaO----> Ca(OH)2

4. AgNo3(aq)+NaCl(aq)------> AgCl(s)+NaNo3(aq)

5. NH3(g)+HCl(g)-------> NH4Cl(g)

6. 2So2(g) + O2(g) -----------> 2SO3(g)

Answer 2

Answer:

1 -sodium carbonate+dil.hydrochloric acid-sodium chloride+ water+ carbon dioxide

2-magnesium+oxygen-magnesium oxide

3- carbon oxide+water - carbon hydroxide+ heat

4-silver nitrate+ sodium chloride - silver chloride+ sodium nitrate

5-ammonia+hydrogen chloride- ammonium chloride

6-hydrogen+ sulphur- hydrogen sulphide
