Chemical changes is when the substance is completely changed. This means that the bonds would either break or/and new ones would form. On the other hand, a physical change is when the change is in the state of a substance.

Can enzymes be reused
Masja [62]

If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.

A clay plate has a volume of 30.0cubic centimeters and a mass of 59.1grams. Calculate its density.
Nataly_w [17]

The density of the clay plate is  1970 kg m⁻³

the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams

so,V= 30 cm⁻³=3x 10-5 m and  M=  59.1grams= 0.0591 kg

Therefore, the density of the plate is:  M/V

=>d = 1970 kg m⁻³
