a) Diamond and graphite are two different forms of pure elemental carbon with densities of 3.51 g/cc and 2.25 g/cc respectively.
dybincka [34]
Density can be calculated using the following rule:
density = mass / volume
Therefore,
volume = mass / density

For diamond:
we have mass = 0.5 grams and density = 3.51 g / cm^3
Substituting in the rule, we can calculate the volume of diamond as follows:
volume = 0.5 / 3.51 = 0.14245 cm^3

For graphite:
we have mass = 0.5 grams and density = 2.25 g / cm^3
Substituting in the rule, we can calculate the volume of graphite as follows:
volume = 0.5 / 2.25 = 0.2223 cm^3

Keith_Richards [23]

The statements that are true regarding a catalyst are as follows:

It undergoes no permanent change during a reaction

What is a catalyst?

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

A catalyst increases the rate at which a chemical reaction occurs by decreasing the activation energy of the reaction.

Since a catalyst is not used up in the reaction, the following statement applies:

It undergoes no permanent change during a reaction

It does not participate in a chemical reaction
