Answer:
2.7g/cm³
Explanation:
Given parameters:
Dimension of the aluminum = 10.5cm x 10.5cm x 0.1cm
Mass of the aluminum = 29.8g
Unknown:
Density = ?
Solution:
Density of a substance is its mass per unit volume;
Mathematically;
Density =
Volume of the aluminum = 10.5cm x 10.5cm x 0.1cm = 11.025cm³
So, insert the parameters and solve;
Density = = 2.7g/cm³

Explanation:
Gibbs free energy of a reaction (
Δ
G ) is the change in free energy of a system that undergoes the chemical reaction. It is the energy associated with the reaction, which is available to do some useful work. If ΔG<0
, then the reaction can be utilized to do some useful work. If
ΔG>0
, then work has to be done on the system or external energy is required to make the reaction happen. ΔG=0 when the reaction is at equilibrium and there is no net change taking place in the system.
