Law of Conservation of Mass:
Law of conservation of mass states that the mass can
neither be created nor destroyed but is transformed from one form to another.
A balanced
chemical equation is based on the principle the …….…..are neither created nor
destroyed in a chemical reaction.
a) atoms
b) molecules
c) ions
d) mass
In balanced chemical equation the…… of reactant and product is conserved.
a) density
b) volume
c) mass
d) energy
The total mass of reactant and product of a chemical reaction is equal. What is this law?
a) law of conservation of energy
b) law of conservation of mass
c) law of conservation of volume
d) law of conservation of force
Types of Chemical Reactions:
Many chemical reactions can be classified as one of five basic types. Having a thorough understanding of these types of reactions will be useful for predicting the products of an unknown reaction. The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
