Answer 1

Answer:

there are two hydrogen atoms are needed for water

hydrogen+oxygen= hydrogenmonoxide

Answer 2

1) Hydrogen atoms needed to produce two H2O molecules are :

• General equation of producing one molecule of H2O :

H2 + 1/2O2 => H2O

• For producing two molecules of H2O, we need 4 H2 and one O2 molecule

• Hence equation will be,

2H2 + O2 => 2H2O

•Total atoms of hydrogen required = 4

2) Oxygen atoms needed to produce two H2O molecules are :

Equation : 2H2 + O2 => 2H2O

• Total atoms of oxygen required = 2
