Answer 1

$\small\blue {\sf{Answer !}}$

Sodium hydroxide is used to make paper, detergents and soap.

Potassium hydroxide is used in farming to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, ...

Calcium hydroxide is used to neutralize acidic soil.

Ammonium hydroxide is used as a cleansing agent.

Answer 2

Explanation:

1.Examples of common Alkalis

»Sodium hydroxide, NaOH.

»Potassium hydroxide, KOH.

»Calcium hydroxide, Ca(OH)2

»Aqueous ammonia, NH3 (aq)

Uses of common Alkalis

1.Sodium hydroxide is used to make paper, detergents and soap.

2.Potassium hydroxide is used in farming to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, and Ni-MH

2.The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen

Photosynthesis-- the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
