Which equation obeys the law of conservation of mass?
2 answers:
Answer:
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.
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
The chemical equation for synthesis of from
and
is:

Hello!
We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)
C: 83.7% = 83,7 g
H: 16.3% = 16.3 g
Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:
We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:
Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:
</span>
I hope this helps. =)
