Two Hydrogen atoms are bonded with one Oxygen atom. H2O.
The "2" in the formula for water (H2O) indicates that one molecule of water is composed of two hydrogen atoms and one oxygen atom bonded together. It represents the ratio of hydrogen to oxygen atoms in a water molecule.
The formula for the sulfate ion is SO4^2-. The prefix "AG" may indicate silver, in which case the formula would be Ag2(SO4)2.
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
The chemical formula for water, liquid, solid or gaseous is the same - H2OIn some texts you will find a little cursive L in brackets to indicate that it is liquid, or a little g to indicate gas, or a little s to indicate solid.
Yes, "aq" is commonly used in chemistry to indicate that a compound is dissolved in water, meaning it is in an aqueous solution. It helps to specify the state of the compound in a chemical reaction or formula.
The chemical formula of lime-water is Ca(OH)2, which is calcium hydroxide.

The formula for the sulfate ion is SO4^2-. The prefix "AG" may indicate silver, in which case the formula would be Ag2(SO4)2.
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
H2O is 2 hydrogens plus 1 oxygen and that makes the chemical formula for water.
The formula for water is H2O, the single subscript is the number 2.
The chemical formula for water, liquid, solid or gaseous is the same - H2OIn some texts you will find a little cursive L in brackets to indicate that it is liquid, or a little g to indicate gas, or a little s to indicate solid.
coefficients
The 2 indicates that there are 2 oxygen atoms.
The chemical formula for quicklime is CaO and when it reacts with water, it forms calcium hydroxide (Ca(OH)2).
The chemical formula of lime-water is Ca(OH)2, which is calcium hydroxide.
No, the chemical formula shows both the kinds of atom in a molecule and the number of each type of atom. For example, the formula H2O shows that there are 2 hydrogen atoms and one oxygen atom in a water molecule.
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
