Cd(NO₃)₂ - cadmium nitrate
n{Cd(NO₃)₂}=1 mol ⇒ n(N)=2*1= 2 mol
m(N)=n(N)*A(N)
m(N)=2*14.01=28.02 g
Answer:
Depending upon the mass gathered, the next process formation varies:
Nuclear fusion can kick in leading to formation of star. The nuclei fuse to together and energy is liberated in the form of light and heat.
If sufficient mass is not gathered to start nuclear fusion reaction, gaseous planet forms like Jupiter.
In third case, even though sufficient mass is present (twice the mass of Jupiter) still no fusion reaction starts. Such bodies are known as failed stars or brown dwarfs.
Answer:functional group (top row); sources in nature (bottom row)
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.
