The chemical reaction is given as:
<span>C8H10+3O2 = C8H6O4+2H2O
We are given the initial amount of para-xylene for the reaction. We use this amount and the relation of substances from the reaction to obtain the amount of the acid produced.
204 g ( 1 mol / 106.18 g ) ( 1 mol C8H6O4 / 1 mol C8H10 ) ( 166.14 g / mol ) = 319.20 g terephthalic acid</span>
Explanation:
A physical change is a change that alters the physical properties of matter most especially the state and the form. This change has the following attributes.
- it is easily reversible
- leads to the production of no new kinds of matter
- involves no change in mass
- requires little energy
Therefore, some of the examples of physical changes are:
- boiling
- melting
- freezing
- condensation
- sublimation
- magnetization of metals
- breaking of glass
- cutting of wood
