Answer: 15 grams of magnesium will be present in the magnesium sulfate
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.
The balanced chemical reaction is:

As the mass remains conserved at the end of the reaction, there will be 15 grams of Magnesium in magnesium sulphate.
Answer:
yes that is right
Explanation:
can i have a brainlist pwease
Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
Because im pretty sure the molecules would just fall apart like salt which is ionic
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
