How does the law of conservation of mass apply to this reaction:
c2h4 + 3o2 → 2h2o + 2co2 ?
the equation needs to be balanced.
there are fewer oxygen atoms in the equation than hydrogen or carbon. only
the oxygen needs to be balanced.
there are equal numbers of hydrogen and carbon. each element needs to be
balanced.
the law of conservation of mass has already been applied. there is an equal
number of each element on both sides of the equation.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
