Answer:
In very simple words ,
As the weight increases the gravitational force acting on the ball increases and thus it effects the change in the distance of the ball as the ball will fall very close to its initial distance if it has more mass and shall go far if the mass is less .
 
        
             
        
        
        
It means they are not attached to their "parent" atom, and they are aloud to roam freely to move through the bulk structure.

Answer:
c. add coefficients as needed
Explanation:
A chemical equation is defined as the equation that shows changes in a chemical reaction. A chemical equation consist of reactant and product, reactant is at left side of the arrow and product is at right side of the arrow.
 Reactant => Product
While balancing a chemical equation, the basic rule is to balance the coefficient as required. Coefficient represents the number of molecules and is used at front of a chemical symbol. Change in coefficient helps balance the number of atoms or molecules of the substances on both the sides of the arrow.
Subscripts are never allowed to change because it can change the chemical involved in the reaction.
Hence, the correct answer is "c. add coefficients as needed".
