A process in which substances are converted into one or more new substances with different properties.
What is a chemical equation?
A symbolic representation of a chemical reaction, indicating the reactants and products involved.
What is the Law of Conservation of Mass?
Matter is neither created nor destroyed in a chemical reaction. The total mass of the reactants is equal to the total mass of the products.
What are reactants and products in a chemical reaction?
Reactants are the substances present before the reaction takes place, while products are the substances formed as a result of the reaction.
What is the difference between a physical change and a chemical change?
A physical change does not involve the formation of new substances, while a chemical change does.
What is meant by balancing a chemical equation?
Ensuring that the number of atoms of each element is the same on both sides of the equation by adjusting the coefficients.
What are the different types of chemical reactions?
The different types of chemical reactions include synthesis, decomposition, combustion, single displacement, double displacement, and acid-base reactions.
What are synthesis reactions?
Synthesis reactions involve the combination of two or more substances to form a new compound.
What are decomposition reactions?
Decomposition reactions involve the breakdown of a compound into its constituent elements or simpler compounds.
What are combustion reactions?
Combustion reactions are characterized by the rapid reaction of a substance with oxygen, resulting in the release of heat and the formation of oxides.
What are single displacement reactions?
Single displacement reactions involve the replacement of one element by another in a compound.
What are double displacement reactions?
Double displacement reactions involve the exchange of ions between two compounds to form new compounds.
What are acid-base reactions?
Acid-base reactions involve the transfer of protons between acids and bases, resulting in the formation of water and a salt.
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction by providing an alternative reaction pathway with lower activation energy.
What is an enzyme?
An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.
What is the difference between exothermic and endothermic reactions?
In an exothermic reaction, heat is released to the surroundings, while in an endothermic reaction, heat is absorbed from the surroundings.
