Gaseous butane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 35.5 g of butane is mixed with 33. g of oxygen. Calculate the minimum mass of butane that could be left over by the chemical reaction. Round your answer to significant digits.

19. grams is the minimum mass of butane that could be left over by the chemical reaction.

Explanation:

Moles of butane =

Moles of oxygen =

According to reaction, 13 mole of oxygen  reacts with 2 moles of butane ,then 1.8 moles of oxygen will react with :

of butane

Moles of butane left unreacted = 0.61 mol - 0.28 mol = 0.33 mol

Mass of 0.3301 moles of butane :

0.33 mol × 58 g/mol = 19. g

19. grams is the minimum mass of butane that could be left over by the chemical reaction.

no but i do not usually comment or use my voice that much when it comes to social media

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
