Answer 1

Answer:

⬛Hiya Buddy⬛

Explanation:

1️⃣The pigment which can absorb solar energy is called as Chlorophyll pigment, and it is also present in chloroplast cells.

2️⃣A plane mirror reflects the sunlight thereby increasing the intensity of solar energy. Glass sheet prevents heat to escape from the solar cooker.

3️⃣The presence of oxygen leads to the formation of corrosion. When the environment is oxygen-deficient, the corrosion takes place.

4️⃣A chemical reaction in which the more reactive element displaces the less reactive element from the compound. During this reaction, one or more than one atoms are replaced by other atoms. For Example: Iron displaces the copper metal when added to a copper sulphate solution.

Answer 2

Answer:

1. The pigment which can absorb solar energy is called as Chlorophyll pigment, and it is also present in chloroplast cells.
2. Solar cooker is a device which uses sunlight as a source of energy instead of gas and electricity to cook food. ... To achieve this, plane mirrors are used to concentrate the sunlight. Sufficient amounts can be concentrated by reflecting sunlight on a plane mirror.
3. .

• The presence of oxygen leads to the formation of corrosion. When the environment is oxygen-deficient, the corrosion takes place.
• The presence of pollutants such as carbon dioxide and chloride also leads to the formation of corrosion.

4. A redox reaction can be defined as a chemical reaction in which electrons are transferred between two reactants participating in it.
