Question The compounds 2-butanol and 2-butene both contain (1) double bonds, only (3) carbon atoms (2) single bonds, only (4) oxygen atoms Answer · 6 votes The answer is (3) carbon atoms. For 2-butanol, it contains single bonds only and with C, O, ... Mor

carbon atoms

Explanation:

Let us look at the molecular formulas of each compound;

Butanol= C4H10O

Butene= C4H8

We can clearly see that the both compounds contains four carbon atoms each. Hence the correct answer is that the both compounds contain the same number of carbon atoms

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
