The chemical formula for sulfuric acid is h2so4.
in 2h2so4, the number of hydrogen atoms is (1,2,4,8) the number of sulfur atoms is (1,2,4,8)and the number of oxygen atoms is (1,2,4,8)

In , the number of hydrogen atoms is 4 ,the number of sulfur atoms is 2 and the number of oxygen atoms is 8.

Explanation:

Molecular formula of sulfuric acid is

the 2 in front of menas that there are two molecules of .

In 2 molecules of there are:

the answer would be   dignified - apex

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
