1 answer:
<h2>The numbers to be added to the blanks to balance this chemical equation are 2, 1 , 1 and 2</h2>
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.
