h2o, water
Answer:
Hydrogen and oxygen can combine to make:
- H2O: Water
- H2O2: Hydrogen peroxide
- OH-: Hydroxide ion
- H2O3: Trioxidane, hydrogen trioxide or dihydrogen trioxide

∙ 15y agoOne might think it makes water, but that is 2 Hydrogens and 1 oxygen. 2 hydrogens and 2 oxygen make something called hydrogen peroxide. Hydrogen peroxide is used to clean cuts by killing bacteria, germs, and mold.

CH4 + 2O2 ==> 2H2O + CO2

What does the number 2 h2o mean?
H20 is a chemical formula. H stands for Hydrogen, O stands for Oxygen. An Oxygen atom has a different makeup than a Hydrogen atom. So H20 means there are 2 hydrogen atoms and 1 Oxygen atom. H20 is essentially H201, but the 1 is silent. Atoms make up everything.. Every substance.. etc. You'll learn about it in 8th grade.
What is the next biggest thing after atoms?
With atoms, you can make molecules. For example, two hydrogen atoms, H, will rapidly combine to form one hydrogen molecule, H2. Add one oxygen atom, and it makes water, H2O.
What two elements is water made up of?
Oxygen and hydrogen are the two ellements that make up water.
If you combine four atoms of oxygen gas and two atoms of hydrogen gas how many atoms of water and oxygen gas will be produced?
I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
What elements make up cornmeal?
Starch is a carbohydrate made up of carbon, hydrogen and oxygen atoms.
What are the 3 atoms that make a molecule?
Water is made up of two different elements and three atoms their are two atoms of hydrogen and their is one atom of oxygen, which forms (makes) water or H2OH2 + O --> H2O
What atoms make up H2O and CO2?
H2O is made up of two hydrogen atoms and one oxygen atom. CO2 is made up of one carbon atom and two oxygen atoms.
How many different kinds of atoms make up a molecule of water?
A molecule of water is composed of two different kinds of atoms: one oxygen atom and two hydrogen atoms.
What atoms join together to make water?
Two atoms of hydrogen and one atom of oxygen.
What is the chemical make up of water?
Water is made up of two hydrogen atoms and one oxygen atom, with a chemical formula H2O.
How many atoms does water make up?
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
What is water molecules composed of?
There's a picture in the linked page showing a single water molecule, consisting of one oxygen atom (in red) and two hydrogen atoms (in white), hence, the formula for a single molecule of water, H2O.
What are the elements that combines to make water?
Hydrogen(H)& Oxygen(O) are the two chemical elements that make up a water molecule. The Chemical formula for water is 'H2O' This tells us that there are two atoms of the element hydrogen and one atom of the element oxygen in a water molecule. Their bonding arrangement is 'H-O-H' .
How many hydrogen and oxygen atoms each does it take to make water?
A water molecule is composed of two hydrogen atoms and one oxygen atom. The formula is H2O.
What does water and oxygen make up?
Oxygen is made of a oxygen atom and water is made out of a oxygen atom and two hydrogen atoms. When combined under the right conditions, hydrogen peroxide can be formed (H2O2).
An oxygen atom needs how many hydrogen atoms to make itself stable?
Two.
What elements make up hydrogen dioxide?
H2O it consists of 2 hydrogen atoms and 1 oxygen atom
