Answer:
The amount of solar panel covered
Explanation:
The variable that is the independent one is the one that Jasmine is changing. In this case, it is the amount of solar panel covered, via a piece of paper.
Answer:
that's because
Explanation:
as far as my knowledge is concerned
HCl(g) + H2O ⇄ H3O+ (aq) + Cl– (aq)
or, more simply (and truer to the original theory):
HCl(g) ⇄ H+ (aq) + Cl– (aq) or HCl(aq)
2C3H8+ 702--->6CO2+8H20
FROM Equation above 2 moles of C3H8 reacted with 7 moles of oxygen to form 6 moles of c02 plus 8 molesof H2O
the moles of c3H8 reacted is = MASS/ R.F.M
THE R.F.M =48+8=44
Number of moles is hence 0.025/44=5.68x10^-4
since ratio of C3H8 to O2 is 2:7 Therefore moles of O2 reacted is 1.989 x10^-3
mass= r.f.m x number of moles
(1.989x10^-3) x 32 =0.064g
Question:
Question 3 is not complete. here is the complete question;
3. With respect to GC, what effect would raising the column temperature have on the retention time?
Answer:
See the attached file for the structures
Explanation:
Find attached of question 1 and 2.
3. Raising the column temperature enhances the internal energy of the analyse. Therefore, it will escape from the liquid phase faster and predominantly be present in the vapour phase. On increasing temperature, retention time will be DECREASED, because analyte would not be able to interact with stationary phase efficiently.
