Each element has 2 subscripts because they are a diatomic molecule.

Explanation:

Given Equation: $2 H_{2}+O_{2} \rightarrow 2 H_{2} O$

The meaning of ‘di’ in Greek is two. The diatomic molecules consist of only two atoms. The atmosphere of Earth mostly consists of diatomic molecules. The representation of subscript 2 of hydrogen and oxygen in the equation states that there are 2 hydrogen atoms and 2 oxygen atoms are present in the equation.

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 -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [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.
