Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 25. g of ethane is mixed with 122. g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to significant digits.

73.48 g

Explanation:

The reaction that takes place is:

We convert the given reactant masses to moles, using their respective molar masses:

0.83 moles of ethane would react completely with (0.83*7/2) 2.9 moles of O₂. There are more O₂ moles than that, so O₂ is the reactant in excess and ethane is the limiting reactant.

We calculate the produced moles of CO₂ using the moles of the limiting reactant:

Finally we convert CO₂ moles to grams, using its molar mass:

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.
