A balanced chemical equation is a direct presentation of the ___________.

Lisa [10]

Answer:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.

Explanation:

How do you balance equations?

In general, however, you should follow these steps:

1. Count each type of atom in reactants and products.

2. Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.

3. Repeat steps 1 and 2 until the equation is balanced.

If the separation between two charges increases, how does the force

Leona [35]

The force reduces

Explanation:

According to Coulomb's law, the force between the charges will reduce if the separation between the charges increases.

Coulomb's law states that "the force between two charges is a directly proportional to the product of the magnitude of the charges and inversely proportional to the square of their separation.".

F = $\frac{K q_{1} q_{2} }{r^{2} }$

where F is the electric field force

K is the constant of the field

$q_{1}$ is charge 1

$q_{2}$ is charge 2

r is the separation

We see that the separation is inversely proportional to the force between the charges. The larger the separation, the weaker or smaller the force.
