How many mole of HCL is produced if 4g of hydrogen is completely reacted with chlorine

4 moles of HCl are produced.

Explanation:

Given data:

Mass of hydrogen = 4 g

Number of moles of HCl = ?

Solution:

H₂ +  Cl₂   →    2HCl

Number of moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 4 g/2 g/mol

Number of moles = 2 mol

now we will compare the moles of hydrogen and HCl.

                 H₂        :        HCl

                  1          :          2

                  2         :         2/1×2 = 4 mol

Thus, 4 moles of HCl are produced.

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.
