CHEM PLZ HELP, Which thermochemical equation represents the most exothermic reaction? Question 7 options:

16CO2 + 18H2O → 2C8H18 +25O2 , ΔH = +5,471 kJ/mol

NH4Cl → NH4+ (aq) + Cl– (aq) , ΔH = +14.8 kJ/mol

C5H12 (g) + 8O2 (g) → 5CO2 (g) + 6H2O (l), ΔH = –3,536.1 kJ/mol

The answer is option 3, C5H12 + 8O2 → 5CO2 + 6H2O.

Explanation:

In an exothermic reaction, the energy change(ΔH) will always be a negative value.

For endothermic reaction, the energy change's value is positive.

In the options above, option 1 and 2 are endothermic reaction.

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
