Answer:
1.17 atm
Explanation:
Calculation to determine the total pressure inside the container (in atm)
Using this formula
Total pressure = Partial pressure 1 + Partial pressure 2
Where,
Partial pressure 1=0.53 atm
Partial pressure 2=0.639 atm
Let plug in the formula
Total pressure = 0.53 atm + 0.639 atm
Total pressure = 1.17 atm
Therefore the total pressure inside the container (in atm) is 1.17 atm
I believe the first one, forgive me if I’m wrong, I’m not completely sure
Answer:
Protons, electrons, same in that order is the answer.
Explanation:
this has to do with the periodic table information.
The structure of 1-methoxypropane is CH₃-CH₂-CH₂-OCH₃
I will label the carbons A-D from left to right.
A B C D
CH₃-CH₂-CH₂-OCH₃
In a proton NMR spectrum, we are looking at the chemical shifts of each unique hydrogen atom, and the splitting patterns tell us how many hydrogens are attached to the adjacent carbon. Therefore, the signal from the protons on carbon A will be split by the protons on carbon B, and the signal for protons on carbon A will have a splitting pattern equal to n+1, where n = number of hydrogens on the adjacent carbon.
Therefore, for the protons on carbon A, there are two neighbouring protons and these will give a splitting patter of 3 peaks, also known as a triplet.
Protons on carbon A: 2 adjacent protons result in a triplet signal.
Protons on carbon B: 5 adjacent protons result in a sextet signal.
Protons on carbon C: 2 adjacent protons result in a triplet signal.
Protons on carbon D: 0 adjacent protons result in a singlet signal.
Find the molar mass of Fe_2O_3
2Fe = 2*56 = 112
3O = 3* 16 = 48
Molar Mass = 160 grams
moles= given mass / molar mass
moles = 28 / 160
moles = 0.175 <<<< answer
