Which of the following molecules has/have the same empirical formula as acetic acid (hc2o2h3)? (a) formaldehyde (b) benzaldehyde (c) glucose

Option (a) is the correct answer.

Explanation:

A chemical formula which represents proportions between the elements present in a compound is known as empirical formula.

When chemical or molecular formula is able to be reduced to smaller whole-number ratio of the elements then both molecular and empirical formulas are considered to be the same.

Relation between molecular formula and empirical formula is as follows.

               Molecular formula = n × Empirical formula

where, n is an integer.

Chemical formula of acetic acid is .

Chemical formula of formaldehyde is . It is the smaller whole-number ratio of molecular formula of acetic acid.

Chemical formula of Benzaldehyde is .

Chemical formula of glucose is .

Thus, we can conclude that formaldehyde molecules has/have the same empirical formula as acetic acid ().

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

i wish i could but this one is weird give me abc and i can solve it.
