Clutch Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 19.2 g of ethane is mixed with 35. g of oxygen. Calculate the minimum mass of ethane that could be left over by the chemical reaction. Round your answer to significant digits.

9.9 grams

Explanation:-

To calculate the moles, we use the equation:

a) moles of ethane

b) moles of oxygen

According to stoichiometry :

7 moles of oxygen require 2 moles of ethane

Thus 1.09 moles of oxygen require =  of ethane

Thus is the limiting reagent as it limits the formation of product. Ethane is the excess reagent.

Ethane left = (0.64-0.31) = 0.33 moles

Mass of

Thus 9.9 grams of ethane that could be left over by the chemical reaction

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

the answer is minerals.
