Balance the chemical reaction of water

H2+02 — H20

Added photo plz if you can help

H2+1/2O2-->H2O

since there are two atoms of hydrogen present in the reactants and in the product you don't need to add any number before H2

we add 1/2 before O2 because only 1 atom is needed for the water molecule

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
