. What is the density of a block of plastic if the volume of the block is 5 cm and the mass is 17.2 g?

Explanation:

The density of a substance can be found by using the formula

From the question

mass = 17.2 g

volume = 5 cm³

We have

We have the final answer as

Hope this helps you

false

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
