d. their color in a non-polar solvent

Explanation:

In non polar solvent such as cyclo hexane, halogens does not dilute, it rather maintains it's same or similar colour as it was in its concentrated form.

Halogens have 7 electrons in their outmost shells, examples includes chlorine, bromine, Iodine, astatine etc. They exist as room temperature.

Bromine exists as liquid.

Iodine as solid.

Chlorine as gas.

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.
