Unit 3 IPC Chemical Reactions

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that in a chemical reaction, matter is neither created nor destroyed. The total mass of the reactants equals the total mass of the products.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed by the sharing of electrons between atoms.

Front

What happens to atoms during a chemical reaction?

Back

Atoms of the reactants recombine to form the products.

Front

What type of bond is present in NaBr?

Back

NaBr has an ionic bond.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.
