Question

how to chemistry balancing equations

Answer 1

In general, to balance an equation, here are the things we need to do:Count the atoms of each element in the reactants and the products.Use coefficients; place them in front of the compounds as needed.

Answer 2

we must surely balance the equations to prove the law of conservation of mass.this states that the mass of the reactants never ad up or destroy in a reaction.
we should balance the equation by seeing the number of molecules on one side is equal to the other side(reactants and products).
hope it helps!!
