How many helium atoms does water contians?
Water is chemically H2O and there is no helium (He) in water. Water has two hydrogen atoms and one oxygen atom.
Does calcium carbonate decompose to make calcium oxide and water?
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
How many helium atoms does water contain?
Water has no helium (He) atom. Chemically water is H2O and there is no He atom present in water.
What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
If sodium bicarbonate reacts with water what is the result chemically?
It does not react with water, but simply dissolves in it - a physical, not chemical, reaction.
Which can be decomposed chemically sodium ethanol sucrose or water?
Sucrose can be decomposed chemically as it is a compound composed of carbon, hydrogen, and oxygen atoms. Sodium is an element, and ethanol is a compound made of carbon, hydrogen, and oxygen atoms, but water is a compound that cannot be decomposed chemically as it is already in its simplest form.

What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
Is water a compound that is made from chemically joined hydrogen and oxygen atoms?
Type your answer here... water is the componant of two hydrogen and one oxygen atoms that's why we name it as H2O.
Is a molecule of water made from chemically combining two hydrogen atoms and one oxygen atom?
yes
What is a pure substance that contains three elements that are chemically bond?
One example of a pure substance containing three elements that are chemically bonded is water (H2O). Water is composed of hydrogen and oxygen atoms that are chemically bonded to form the water molecule.
Why water is called molecule?
The definition of a molecule is two or more atoms which have chemically combined to form a single species. Therefore when the two hydrogen atoms combine with the one oxygen atom, you get a single substance.
What do two or more atoms that are chemically combined form?
In general, when a chemical bond forms between two or more atoms, it creates a molecule.
If sodium bicarbonate reacts with water what is the result chemically?
It does not react with water, but simply dissolves in it - a physical, not chemical, reaction.
