Answer 1

1) Number of moles of product, carbon dioxide, is the same as that of vinegar. So the most efficient reaction is the one with the less amount of baking soda. So RXN 1 is the most efficient.

2) Number of moles of product, carbon dioxide, is the same as that of vinegar; except RXN 5. There is an error in the number of moles of carbon dioxide. It should be 0.05034.

Answer 2

Answer:

1) 1 is most efficient

Explanation:

efficiency is the ratio bet. reactants n products. adding vinegar n baking soda then dividing by co2, 1 gives the largest no.

2) 5 has different vinegar n co2 ratio - they are the same in the other 4. so for 5, the co2 should be 0.05034.
