ZnCO3 + heat -->
ZnO + CO2
If the potential energy of reactants is lower than the products, the reaction is ____________
endothermic
This states that the number of individual atoms must be equal on both sides of a chemical equation.
Law of conservation of matter
When reactants include pure oxygen and for CO2 and water for hydrocarbon reactants.
combustion
Aluminum reacts with Iron (III) Oxide to form aluminum oxide and Iron.
2Al + Fe2O3 --> Al2O3 + 2Fe
Fe(OH)2 -->
Fe2O3 + 3H2O
If the reactants energy is higher than the products the reaction is
exothermic.
This is a solid formed form aqueous reactants.
precipitate.
Acid + Base = water + salt
