In the reaction 2h2(g) + o2(g) ® 2h2o(g), what is the volume ratio of h2 to h2o?

By looking at the stochiometry, we can conclude that the ratio is 1 :1

2 moles of H2 react to form 2 moles of H2O

hope this helps

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic

The correct answer is weight.
