Hydrogen and Oxygen
Hydroden and oxygen. H2o
Two elements are combined together in water: hydrogen and oxygen. Water has a chemical formula of H2O, which means each water molecule contains two hydrogen atoms and one oxygen atom.
atoms of hydrogen and oxygen chemically combined to form water
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
The chemical formula of a substance represents the ratio of elements in a compound. Water has the formula H2O because it consists of two hydrogen atoms bonded to one oxygen atom. This ratio of elements is what gives water its unique properties and stability. Any other combination would result in a different compound with different properties.
Elements 1 and 3 are hydrogen and oxygen, respectively. When combined, they form water, which is the most common substance in the body.
A substance containing atoms of two or more elements combined together is called a compound. Compounds have a fixed ratio of elements and typically have different properties from the elements they are composed of. Examples include water (H2O) and table salt (NaCl).
A compound is a substance composed of two or more elements chemically bonded together in exact ratios. For example, in water (H2O), the elements hydrogen and oxygen are combined in a 2:1 ratio. Another example is carbon dioxide (CO2), where carbon and oxygen are combined in a 1:2 ratio.
The water molecule contains two different elements chemically combined, which makes it a compound. A compound is a pure substance that contains two or more different elements chemically combined.
Chemical formula for water is H2O. Elements making this compound are hydrogen and oxygen. Water is a colourless odorless liquid.
Water is H2O, two hydrogen atoms and one oxygen atoms.
Elements are combined into molecules, which, when combined in big groups, make up the things that are around us. Ex: H = Hydrogen, 0 = Oxygen, H₂O = Water
