Explanation:
The Law of Conservation of Matter as applied to chemical reactions says that matter is neither created nor distroyed, only changed in form. This implies that the mass of substances going into a reaction process must equal the mass of products generated during the reaction process.
Empirically,
∑ mass reactants = ∑ mass products
One can test this idea after balancing a chemical equation by determining the sum of formula weights of reactants and products; then compare. If reaction was properly balanced, the total mass reactants = total mass of products.
Example:
Combustion of Methane => CH₄(g) + 2O₂(g) => CO₂(g) + 2H₂O(l)
Equation Weights => 16amu + 64amu <=> 44amu + 36amu
Mass Reactants = Mass Products => 80amu <=> 80amu.

*amu = atomic mass units => sum of atomic weights of elements
Explanation:
this equation is balanced
if you look at it carefully
k=1
f=1
o=2
we do not have any opposing element
The other name for a condensation reaction would be dehydration reaction. This reaction happens when two molecules or compounds react forming a larger molecule and a small H2O molecule. From the name itself, water should be produced.

He needs to add 4 mL of the 0.5 M solution to 6 mL of water.
