The valency of oxygen in this scenario would be 2. Oxygen typically has a valency of 2 when it forms compounds.
The valency of HNO2, also known as nitrous acid, is 1. Nitrous acid has one hydrogen (H) atom, one nitrogen (N) atom, and two oxygen (O) atoms. Each hydrogen atom contributes one valency, while nitrogen usually has a valency of 3 and oxygen has a valency of 2.
Oxygen combines with Hydrogen to form water. The chemical formula for water is H2O, which indicates that two hydrogen atoms bond with one oxygen atom.
Zero. The valence of hydrogen is plus 1, and the valence of oxygen is minus 2. Water is H2O, i.e. each molecule of it consists of two hydrogen atoms combined with one oxygen atom. Adding the valences of the components, we obtain zero as water's valence (charge).
The valency of sulfur in sulfuric acid (H2SO4) is +6. Sulfur forms 4 covalent bonds (with oxygen atoms) and 2 ionic bonds (with hydrogen ions) in the compound.
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' .
WATER!

Set the Hydrogen on fire.
Zero. The valence of hydrogen is plus 1, and the valence of oxygen is minus 2. Water is H2O, i.e. each molecule of it consists of two hydrogen atoms combined with one oxygen atom. Adding the valences of the components, we obtain zero as water's valence (charge).
Oxygen has the valency of 2 in most of the compounds.
-1 hco3-1 all bases are - and most if not all the ones with hydrogen in front are -1 for example- hydrogen sulfate (hso4-1)or hydroxide (oh-1)
It is combining capacity of an atom of an element and is numerically equal to the number of hydrogen atoms or number of chlorine atoms or double the number of oxygen atoms with which one atom of the element can combine.
The valency of oxygen in suboxides can vary, but it is typically less than its usual valency of 2 in oxides. Suboxides contain oxygen atoms with a valency of 1 or less, resulting in a lower overall valency for oxygen in these compounds.
The valency of sulfur in sulfuric acid (H2SO4) is +6. Sulfur forms 4 covalent bonds (with oxygen atoms) and 2 ionic bonds (with hydrogen ions) in the compound.
Two hydrogen atoms and one oxygen atom combine to form one water molecule.
There are 16 electrons from the oxygen atoms, one from the hydrogen atom and one from the charge, that makes 18 electrons altogether. Its valency is 1.
