Answer:
See below.
Explanation:
The volume increases.
This is complies with Boyles Law:
At constant temperature P1 V1 = P2 V2 where P1, P2 are the pressures before and after and V1 and V2 are the volumes before and after.

Answer:
When marshmallows are toasted, a chemical change occurs. The sugar molecules in the marshmallow are being changed into carbon (1). Sugar can be changed into water molecules. ... The flame on stage - oxygen diffuses to the surface of the marshmallow from the surrounding air.
Answer:
Explanation:
Hello!
In this case, since the Gibbs free energy of any process is related with the enthalpy change, temperature and entropy change as shown below:
For a chemical reaction it is simply modified to:
Thus, since the enthalpy of reaction is given as -304.2 kJ and the entropy as -414.2 J/K (-0.4142 kJ/K), at 775 K the Gibbs free energy of reaction turns out:
Whose result means this is a nonspontaneous reaction.
