Imagine you mix 16.05 g of methane (CH4) gas and 96.00 g ofoxygen (O2) gas and then ignite the mixture. After a bright flashand a loud bang, some water droplets form on the inside of thereaction vessel.a. Write the balanced chemical reaction for the combustion ofmethane.b. Depict the process that occurred in the vessel using circles torepresent atoms. Represent carbon with black circles, hydrogenwith white circles, and oxygen with gray circles. Let onecircle (or one molecule made of circles bonded together) representexactly one mole.c. How many moles of water can you make? How many molesof carbon dioxide?d. Will anything be left over? What? How much?e. Identify the following: limiting reagent, excess reagent, andtheoretical yield.

a. Write the balanced
methane.
b. Depict the process that occurred in the vessel using circles to
represent atoms. Represent carbon with black circles, hydrogen
with white circles, and oxygen with gray circles. Let one
circle (or one molecule made of circles bonded together) represent
exactly one mole.
c. How many moles of water can you make? How many moles
of carbon dioxide?
d. Will anything be left over? What? How much?
e. Identify the following: limiting reagent, excess reagent, and
theoretical yield.
