Answer:
The pH of pure water (H20) is 7 at 25oC, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2. Because of the association of pH with atmospheric gasses and temperature, it is strongly recommended that the water be tested as soon as possible.
Answer:
5-chloro-1,3-cyclopentadiene
Explanation:
5-chloro-1,3-cyclopentadiene will react more slowly in an SN1 reaction. ( i.e. No reaction as the product is unstable ) attached is the representation of the rate of reaction of both Halides which shows that 5-chloro-1,3-cyclopentadiene reacts the slowest .
Also During SN1 reaction Carbocation is formed .
Attached below is the solution explanation
Answer: 6.56g
Explanation:
No of moles = mass given/molar mass
Molar mass of ch4
C is carbon which is 12
H is hydrogen which is 1
Molar mass= 12+4(1)
Molar mass= 16g/moles
No of moles given is 0.41moles
No of moles = mass given/molar mass
Mass given = molar mass × no of moles
Mass given = 16×0.41
Mass= 6.56g
