True or False: It takes 10 cubic feet of oxygen to burn 1 cubic foot of natural gas.

The statement is false because the general stoichiometric ratio for burning natural gas (primarily methane) is approximately 10 to 12 cubic feet of air, which contains about 20% oxygen, required for every 1 cubic foot of natural gas. Natural gas combustion typically requires approximately 1 cubic foot of oxygen to burn efficiently, with the need for additional air to support the reaction.

In standard conditions, one cubic foot of natural gas will actually combust with around 2 to 2.5 cubic feet of oxygen. Thus, while it is true that adequate oxygen is necessary for combustion, the ratio stated in the question overestimates the amount needed for combustion of natural gas, making the statement false.

Options that suggest variability based on conditions or gas composition are not directly applicable in this case because, under standard conditions and typical natural gas compositions, the oxygen requirement remains relatively constant and does not reach the asserted 10 cubic feet.
