The reaction is
CH3OH(l)→CH3OH(g)
To calculate ΔG°
ΔG°=ΔG°f of CH3OH(g)-ΔG°f of CH3OH(l)
=162.3kJ/mol - (-166.6kJ/mol
=4.3kJ/mol.
In order for a cellular device to operate, it requires battery power, otherwise known as energy.
or you can do this
Us humans consume food so that we can have the sufficient energy to accomplish tasks.
2 N2 + 5 O2 ----> 2N2O5
Is this what you wanted?
Answer:
It does not always retain the properties of the substances that make it up
It requires heat energy to make
Explanation:
A compound is a chemical substance composed of two or more kinds of atoms or elements joined together in a definite grouping.
The properties of compounds are distinct from those of individual elements that are combined in its make up.
- To produce a compound, a chemical change must take place
- As with most chemical changes, heat is required to drive the change.
- So, to form compounds, some amount of heat is needed to cause the change.
