sodium bicarbonate and silver nitrate reacting is a chemical change</span>
The answer is yes they do form ions upon gaining electrons and becomes negatively charged
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 = 
where F is the electric field force
K is the constant of the field
is charge 1
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.

The percentage of the total energy contributed by fat = 51.59% of fat
<h3>Calculation of total energy in fat</h3>
The quantity of fat in the hamburger = 36grams
But 1 gram of fat = 9 kcal( standard energy value per gram of fat).
That is , 9kcal = 1 gram
X kcal = 36 grams
cross multiply,
X kcal = 9 × 36
= 324kcal
To calculate the percentage of 324kcal of fat in 628 kcal,


% = 51.59% of fat
The percentage of the total energy contributed by fat = 51.59%
