2.what happens when ammonia is acted with CuSO4 solution. explain with chemical reaction.
​

[1] When ammonia reacts with mercurous nitrate paper, it produce ammonium nitrate, mercury and insoluble aminobasic murcuric nitric(HgNH2NO3).

[2] When NH3 solution is added to CuSO4 solution drop by drop, ammonia ions completely react with copper sulphate and precipitates of copper hydroxide are formed.

But when we add excess of ammonia, the precipitate dissolves and a soluble complex is formed.

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.
