What is the concentration of an hbr solution if 29.0 ml of a 0.200 m naoh solution are needed to titrate 54.0 ml of the acid?

The concentration (molarity) of an HBr solution is 0.0107 m.

Molarity is the measure of the concentration of any solute in per unit volume of the solution.

The chemical reaction is

We will calculate the concentration by formula of molar equivalence

Thus, the concentration is 0.0107 m

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
