Answer 1

Answer:

H20 IS CORRECT ANSWER......

I HOPE HELP YOU.......

THANKS...........

OKKKKKKK...........

Answer 2

Explanation:

(a) Balanced chemical reaction:

$2 A l(O H)_{3(a q)}+3 H_{2} S O_{4(a q)} \rightarrow A l_{2}\left(S O_{4}\right)_{3(a q)}+6 H_{2} O_{(l)}$

• Aluminium sulphate formed is a salt which is dissolved in water and formed as aqueous solution in this reaction.
• Aluminium sulphate is the major product in this reaction. It is used in purification of water and in deodorants.

(b) Balanced chemical reaction:

$M n O_{2}+4 H C l \rightarrow M n C l_{2}+C l_{2}+2 H_{2} O$

• Manganese dioxide reacts with hydrochloride gas to form manganese chloride with chloride gas and water.
• The manganese chloride is the major product in this reaction. This compound is used in manufacturing of dry cell batteries.
