Question

Write the associated equation with..

The formation of a yellow precipitate upon the addition of the silver nitrate to a sodium halide salt:

Generation of HCl gas when sulfuric acid reacts with a sodium halide salt:

Spontaneous decomposition of ammonium carbonate:

Generation of a carbon dioxide gas from baking soda upon addition of acid:

Formation of an insoluble barium salt when barium hydroxide reacts with a gas:

The result of reacting an iodide compound with bleach:

Any of these would be helpful!!

Explanation / Answer

1)

silver nitrate + sodium halide --> silver halide + sodium nitrate

AgN03 + NaX ---> AgX + NaN03

here X is a halide

given

a yellow precipitate

so

it must be AgI

so

the reaction is

AgN03 + NaI ---> AgI + NaN03

2)

2NaCl + H2S04 --> Na2S04 + 2HCl

3)

(NH4)2C03 --> 2NH3 + C02 + H20

4)

NaHC03 + HCl    --->   NaCl + H20 + C02

5)

Ba(OH)2 + C02 -->   BaC03 + H20

6)

2I- + Cl0- + 2H+ ---> I2 + Cl- + H20 + I2
