Name the compound CH3-CH3

Ethane

Explanation:

CH3-CH3 is an alkane by the name of ethane. In organic chemistry there is a systematic way of naming compounds according to the prefix (eth) and the suffix (ane.)

The prefixes vary according to the number of carbon atoms:

1 C = meth

2 C = eth

3 C = prop

4 C = but

the answer is definitely c.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
