Question

1.Translate the following chemical equation into a sentence.
CH4+2O2--->CO2+2H2O

2.Perform the following calculations andwrite the answer with the correct number of significant figures.
a. 12.65m times 42.1m
b. 3.7g/1.083cm*3

Answer 1

1 molecule of methane burns completely in oxygen to form 1 molecule of carbon dioxide and 2 molecules of water.

12.65 m * 42.1 m = 536 m^2
3.7 g / 1.083 cm^3 = 3.4 g/cm^3
