Single replacement

Explanation:-

The definition for single displacement reaction is the reaction where an element must displace another element from it's compound

The symbol for lead is Pb

The formula for lead sulfate is PbSO4.

The formula for sulfuric acid is H2SO4.

The formula for Hydrogen gas is H2.

The balanced chemical equation is

Pb + H2SO4 --> PbSO4 + H2

Here we can see that an element Pb is reacting with a compound H2SO4 and takes the place of H2 to form PbSO4.

Hence this is an example of single displacement reaction.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 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.
