Answer:
Part A: 27.8 L; Part B: 0.500 mol
Explanation:
Part A
For an ideal gas, we can use the equation:
PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
In the beggining:
P*48.0 = 1.90*RT
P/RT = 1.90/48.0
P/RT = 0.03958
For constants pressure and temperature, after 0.800 mol of gas leaks out: n = 1.90 - 0.800 = 1.10 mol
PV = 1.10*R*T
P/RT = 1.10/V
0.03958 = 1.10/V
V = 1.10/0.03958
V = 27.8 L
Part B
In the beginning
PV = nRT
P*70.0 = 2.00*RT
P/RT = 2.00/70.0
P/RT = 0.02857
After the gas leaked out:
PV = nRT
P*17.5 = nRT
P/RT = n/17.5
0.02857 = n/17.5
n = 0.500 mol

Explanation:
In this question, we have to follow the IUPAC rules. Lets analyze each compound:
a. 1-methylbutane
In this compound we have a chain of 5 carbons, so the correct name is <u>Pentane.</u>
b. 1,1,3-trimethylhexane
In this compound, we longest chain is made of 7 carbons, so, we have to use the name "heptane". Carbon one would be the closet one to the methyl group, so the correct name is <u>2,4-dimethylheptane.</u>
c. 5-octyne
In this case, carbon 1 would be the closet one to the triplet bond. With this in mind, the correct name is <u>oct-3-yne.</u>
d. 2-ethyl-1-propanol
In this compound, we longest chain is made of 4 carbons, so, we have to use the name "butane". Carbon one would be the carbon with the "OH" group, so the correct name is <u>2-methylbutan-1-ol.</u>
<u>e. 2.2-dimethyl-3-butanol</u>
In this case, carbon 1 would be the closet one to the "OH". With this in mind, the correct name is <u>3,3-dimethylbutan-2-ol.</u>
See figure 1
I hope it helps!
Answer:
Due to oxidation process apple gets brown color.
Explanation:
When we cut the apple it turn brown in color because of the oxidation process. The peel of apple protect it from the oxidation. When the apple is peel off the oxygen and water molecules in air react with it and oxidation take place. The oxidation process is very efficient in ambient temperature.
For example, if the peal off apple is placed into the refrigerator it take a time to got oxidize and turn brown, but if it is placed in room temperature it quickly turn brown.
when oxygen is react with peel off apple , it trigger the polyphenol oxidase enzyme to oxidize the phenolic compound and quinones are formed which then react with amino acids and produced brown color.
