2H2 02---2H20 - how many molecules and number of atoms of each element in the equation?
4 molecules of hydrogen & oxygen4 atoms hydrogen& 3 of oxygen
How many hydrogen atoms are in 2H2O?
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).
How many atoms are in O2 2H2 2H2O?
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
What does the chemical symbol 2H mean?
H2 is a hydrogen molecule made of two hydrogen atoms bonded together. The preceding two refers to the number of moles of H2 molecules in the chemical equation.

Can 2 hydrogen molecules be combined with an oxygen molecule to make water?
YES, this happens when hydrogen burns. 2H2 + O2 ==> 2H2O
What is hydrogen fuel's chemical formula?
hydrogen + oxygen → water 2H2 + O2 → 2H2O Hydrogen gas exists as diatomic molecules, H2 and oxygen gas exists as diatomic molecules, O2
How many hydrogen atoms are in water H2O?
There are 4 atoms of hydrogen in 2H2O.
What is the equation for the chemical change that produces water from two hydrogen molecules and one oxygen molecule?
2h2+o2=2h2o
How many oxygen molecules are produced from the splitting of two molecules of water if the balanced equation for the reaction is as follows 2H2O 2H2 plus O2?
Yes, you can turn water into oxygen and hydrogen gas with electricity; this process is called electrolysis.
How many hydrogen atoms are in 2H2O?
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).
How many atoms are in O2 2H2 2H2O?
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
