The chemical formula of its chloride of a metal m is MCl3. Write the chemical formula of its chloride, bicarbonate, and sulphide. plz answer asap

Explanation:

Chemical formula of chloride of metal M is MCl₃

We know that Cl has valency 1.

nowzl, it's cleared that M had valency 3.

Bcz the after criss-cross it forms MCl₃.

Now,

Chemical formula of bicarbonate:

we know that bicarbonate has its valency/charge 1

So, after criss-cross the formula of metal bicarbonate is M(HCO₃)₃

Chemical formula of sulphide:

we know that sulphide has its valency/charge 2

So, after criss-cross the formula of metal metal is M₂S₃

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.

a) the particles of the chair are strongly held together.
