Achemical equation where the number of atoms of each element are the same on both sides. coefficients are often needed to balance a chemical equation.

A balanced equation

Explanation:

when atoms of various elements or compounds react, they do this in mole ratio. It is a law to always balance the number of elements of each element on the reactant side to the corresponding elements on the product side of the equation. This is done by the introduction of coefficients.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
