Questions and Answers
What are the different types of chemical reactions?
The different types of chemical reactions are synthesis, decomposition, single replacement, double replacement, combustion and redox reactions.
How do you balance a chemical equation?
To balance a chemical equation, you need to adjust the coefficients of the reactants and products so that the number of atoms of each element is the same on both sides of the equation.
What is the law of conservation of mass?
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products.

Study Notes
Chemical Reactions and Equations
- There are five general types of chemical reactions: synthesis, decomposition, single displacement, double displacement, and combustion reactions.
Balancing Chemical Equations
- To balance a chemical equation, the number of atoms of each element must be equal on both the reactant and product sides.
- This is achieved by adding coefficients (numbers in front of formulas of reactants or products) to the equation.
Law of Conservation of Mass
- The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, only transformed from one substance to another.
- This means that the total mass of reactants is equal to the total mass of products in a chemical reaction.
Chemical Reactions and Equations
- A chemical reaction is a process in which one or more substances are converted into new substances.
- A chemical equation is a representation of a chemical reaction using chemical formulas and symbols.
- The equation shows the reactants (starting materials) on the left and the products (resulting substances) on the right.
Stoichiometry and Balanced Equations
- The stoichiometry of a chemical reaction is the quantitative relationship between reactants and products.
- The coefficients in a balanced chemical equation represent the mole ratios of reactants and products.
- These coefficients are used to calculate the amounts of reactants required or products formed in a reaction.
