Balancing Equations

Balancing Equations. Chemical equation must obey the law of conservation of mass. According to the Law, mass cannot be created or destroyed BALANCED OR NOT BALANCED? Mass of reactants: molar mass of Fe + 2(molar mass of O)= 55.85 g + 2X 16 g = 56 g + 32 g= 88 g

Mineral dissolution/precipitation

Mineral dissolution/precipitation. To determine whether or not a water is saturated with an aluminosilicate such as K-feldspar, we could write a dissolution reaction such as: KAlSi 3 O 8 + 4H + + 4H 2 O ? K + + Al 3+ + 3H 4 SiO 4 0 We could then determine the equilibrium constant:
