The numbers to be added to the blanks to balance this chemical equation are 2, 1 , 1 and 2
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 2 atoms of hydrogen , 1 atom of oxygen and 4 atoms of flourine.Thus there will be atoms of hydrogen , 1 atom of oxygen and 4 atoms of flourine in the product as well.

The element which is a non-metal and present in the same group as lead is carbon as they both have four electrons in their valence shell.
What is an element?
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

The electronegativities of the two atoms play a part in determining what kind of bonds are formed. The main two types of chemical bonds are ionic and covalent. Covalent bonds are formed by atoms that share valence electrons and are most commonly formed between nonmetal atoms.
Their valance electrons are redistributed in ways that make the atoms more stable.
