How does the law of conservation of mass apply to this reaction: mg + hcl + h2 + mgcl2 ?
hydrogen and chlorine need to be balanced. there is an equal amount of magnesium
on each side
the equation needs to be balanced. there are fewer hydrogen atoms in the equation
than magnesium or chlorine.
the law of conservation of mass has already been applied. there is an equal number
of each element on both sides of the equation.
only the hydrogen needs to be balanced. there are equal numbers of magnesium and
chlorine
