EMERGENCY! WORTH 100 POINTS AND BRAINLIEST TO FASTEST CORRECT ANSWER! Write a chemical equation for the combustion of each of the following substances. If a compound contains carbon and hydrogen, assume that
carbon dioxide gas and liquid water are produced.
a.) solid barium
b.) solid boron
c.) liquid acetone (C3H6O)
d.) liquid octane (C8H18)

1) solid barium

2Ba(s)  &  O2 9g)  -->  2 BaO (s)

2) solid boron

4 B(s) + 3 O2 (g) → 2 B2O3 (s)

3) liquid acetone (C3H6O)

1 C3H6O(l)  & 4 O2 (g)  -->  3CO2(g)  &   3H2O (g)

4) liquid octane (C8H18)

2 C8H18   & 25 O2 (g)  -->  16CO2 (g)  & 18 H2O (g)
