Answer:

oranges: contains chemical

heat: neither

sunlight: neither

photosynthesis: chemical reaction

bleaching protein: contains chemical

neutralization: chemical reaction

combustion: chemical reaction

vitamin K: contains chemical

rainbow: neither

marble: contains chemical

Explanation:

A chemical is a substance that is used in or made by chemical reactions. It is a matter with compositions related to the science of chemistry. In the question,

- orange contains chemical like vitamins, protein molecules etc.

- Bleaching protein contains chemicals that bring about the bleaching process.

- Vitamin k contains chemical elements

- marble contains Calcium, oxygen etc elements

A chemical reaction is that which involves the change in chemical properties of involved substances.

- Photosynthesis is the chemical reaction between carbon dioxide and water in the presence of sunlight to give glucose.

- Neutralization is the chemical reaction where an acid neutralizes a base to form a salt and water molecule.

- Combustion is the chemical reaction involving the burning of a chemical substance.

Some substances like sunlight, heat and rainbow are neither a chemical or chemical reaction.

25 grams of radon-222 remains after 15.28 days. How much radon was in the original sample? Write an equation for the decay of ra
Crazy boy [7]

Answer:

half-life = 3.8 days

total time of decay = 15.2 days

initial amount = 100. g

number of half-lives past: 15.2/3.8 = 4 half-lives

4 half-lives = 1/16 remains

100. g x 1/16 = 6.25 g

Energy is stored in chemical bonds during photosynthesis.

During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.

Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:

6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2

The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.
