Which reaction below requires the greatest amount of amount of oxygen per mole of explosive for complete oxidation (combustion) to co2 and h2o.

a. ch3oh
b. ch2=chch3
c. ch ξ ch
d. no right answer.

The answer to your question is: letter B

Explanation:

First, write the reactions and balance them

a.             2 CH3OH   +  3 O2     ⇒   2  CO2    +   4 H2O

                 ratio   3/2 = 1.5

b.            2 CH2 = CHCH3 +  9 O2  ⇒  3 CO2   + 3 H2O

                 ratio     9/2 = 4.5

c.            2 CH ≡ CH    +   5 O2   ⇒  4 CO2   + 2 H2O

                 ratio     5/2 = 2.5

a polar bond is formed when electrons are shared unevenly between atoms

so what is the problem with your lab report and whats the subject of the lab report? i will you
