The chemical equation below shows the combustion of methane (CH4). CH4 2O2 Right arrow. CO2 2H2O The molar mass of oxygen gas (O2) is 32. 00 g/mol. The molar mass of carbon dioxide (CO2) is 44. 01 g/mol. What mass of CO2, in grams, will form when 8. 94 g O2 completely react? 3. 25 6. 15 13. 0 53. 0.

i have no clue hope you find the answer

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
