How many elements are in chemical formula C2H5O plus O2?

Answer 1

Three elements are present in this reaction: carbon, hydrogen, and oxygen. This is typical of combustion reactions, and the completed balanced equation for this reaction is: 4C2H5O + 11O2 --> 8CO2 + 10H2O

Answer 2

The chemical formula C2H5O corresponds to ethanol. When ethanol reacts with O2, it produces carbon dioxide (CO2) and water (H2O). So, the reaction involves the rearrangement of atoms to form new molecules but the total number of elements in the chemical formula remains the same.

Answer 3

there are 3 elements in that formula namely Carbon, Hydrogen and Oxygen.

Answer 4

there are 11 atoms. 2 carbons 8 hydrogens and 1 oxygen

Answer 5

C3H7OH

Carbon= 3

Hydrogen= 7

Oxygen= 1

Hydrogen= 1

Total= 12 atoms
