1. Every chemical reactions obey the law of conservation of matter. The law states that "matter can neither be created not destroyed but transformed from one form to another".
When chemical reactions are balanced, they simply obey the law of conservation of matter and mass. This makes makes measurement easy to make when carrying out experiments. One can easily deduce the amount of reactants to be used and the products expeceted
2 MgF₂ + ___Li₂CO₃ → ___MgCO₃ + ___LiF
to balance the equation:
check if the equation is balanced.
Put a,b,c and d before each of the products and reactants.
aMgF₂ + bLi₂CO₃ → cMgCO₃ + dLiF
The coefficients are needed to balance the equation:
