h2o, water
Answer:
Hydrogen and oxygen can combine to make:
One 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.
Assuming complete combustion CH4 (methane) and O2(oxygen) react to make H2O (water) and CO2 (carbon dioxide).
CH4 + 2O2 ==> 2H2O + CO2
Hydrogen Nitrgen & Oxygen make Nitric acid (HNO3), and Nitrous acid (HNO2).

Water
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.
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.
Oxygen and hydrogen are the two ellements that make up water.
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
Starch is a carbohydrate made up of carbon, hydrogen and oxygen atoms.
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
There are two types of elements in water. It is made up of Oxygen and Hydrogen. There are two Hydrogen atoms for every Oxygen atoms and the chemical compound of water is H2O.
Two atoms of hydrogen and one atom of oxygen.
Pure water contains 2 hydrogen atoms to 1 oxygen atom ratio and combined with together as H2O.
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.
A water molecule is composed of two hydrogen atoms and one oxygen atom. The formula is H2O.
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.
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).
Two.
H2O it consists of 2 hydrogen atoms and 1 oxygen atom
Water is composed of one atom of hydrogen and two atoms of oxygen
Hydrogen and Oxygen forming H2O (two hydrogen atoms for every oxygen atom per molecule)
