Answer from: imstoopid69

To know the substances and number of atoms and molecules involve in the chemical equation.

Explanation:

The chemical equations are the linear presentation of chemical reactions. In our day to day life, different kinds of chemical reactions occur such as rusting of iron, curdling of milk. To represent such reactions we use chemical equations, where the left-hand side components are reactants and right-hand components are products. The reactants are the substances that are combined to form the reaction and results of the product. One can write chemical equations in words or in symbols. From the chemical equation, one can know how many numbers of atoms or molecules involve in the chemical reaction.

Answer from: yofavkay

Sample Response: Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.

Answer from: Quest

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.
