The difference (called the mass defect) is the energy released/absorbed by the reaction (in units of c^2). For your typical chemical reaction, that defect is immeasurably small compared to the overall masses involved.

Due to the principle "Conservation of Matter" the total mass of the reactants must equal the total mass of the products. Matter is neither created nor destroyed.

According to classical theory, they are the same. If the reaction had an energy change then there is a very small (unmeasureable) change in mass due to relativity.

equal
mass is conserved in chemical reactions
in nuclear reactions mass can be converted into energy by the equation E=MC^@ ( or energy can be converted to mass by the equation M=E/(C^2) )

Should be the same because mass is conserved.

Depends on whether your reaction is endothermic or exothermic!
If it's exothermic, the products will have slightly less mass.
If it's endothermic, the products will have slightly more mass.
e = m(c^2)
