The chemical equation below shows the combustion of methane (ch4).

ch4 + 2o2 -> 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?

a: 3.25
b: 6.15
c: 13.0
d: 53.0

How can you use chemical equations to predict the products of the reaction you can carry out?

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
