Answer: E=∆H*n= -40.6kj
Explanation:
V(CO) =15L=0.015M³
P=11200Pa
T=85C=358.15K
PV=nRT
n=(112000×0.015)/(8.314×358.15)
n(Co)= 0.564mol
V(Co)= 18.5L = 0.0185m³
P=744torr=98191.84Pa
T= 75C = 388.15k
PV=nRT
n= (99191.84×0.0185)/(8.314×348.15)
n(H2) = 0.634mol
n(CH30H) =1/2n(H2)=1/2×0.634mol
=0.317mol
∆H =∆Hf{CH3OH}-∆Hf(Co)
∆H=-238.6-(-110.5)
∆H = 128.1kj
E=∆H×n=-40.6kj.
On the periodic table everything to the right of the line is a non metal
Everything to the left is a metal. So the line crosses to the right is NM to left is M
The path that planets follow around the sun are called orbitals.
Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes
This is based on the study of colligative properties of solution.
Now, Applying Raoult's law, it states that when the amount/concentration of solute increases, the freezing point of the solution decreases and the vapour pressure of the solution is also decreases.
As the vapour pressure decreases, the boiling point of the solution elevated and it's freezing point decreases.
