What are three requirements for a correclty written chemical equation?

Answer 1

The mass of chemicals consumed should be equal to the mass of chemicals produced.

The number of atoms of each element represented in the reactants is equal to those in the product.

Bonds are broken and reformed but the number of atoms is the same on each side.

Answer 2

Whether you are still in school or have turned science into a profession, it is important that you know the following three requirements when you are writing out a chemical equation. The formula has to contain just facts. There must be correct formulas for all elements present. Finally, the formula must satisfy the law of conversion of mass.

Answer 3

Three requirements for a correctly written chemical equation include that it must represent known facts and have correct formulas for products and reactants. The third requirement is that it must satisfy the law of conversion of mass.

Answer 4

The main requirements of chemical equation are as followas:

1. It should represent real chemical change, which is practically possible.

2. It should be balanced properly.

3. It should be molecular.

Answer 5

temperature change colour change and gas Release

Answer 6

1. Balanced

2. All caps

3. Have fun :)

Answer 7

The same numbers and kinds of atoms in the reactants must be present in the products.

Answer 8

3 parts for a chemical equation are :1. elements on the reactants side .

2. atoms balancing,

3. product isde.

Answer 9

- correct chemical symbols
- correct stoichiometry
- in inorganic chemistry the metal before the nonmetal
