What is a chemical reaction?
A chemical reaction is a process that involves the rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
What are reactants?
Reactants are the starting substances that undergo change during a chemical reaction. They are typically written on the left side of a chemical equation.
What are products?
Products are the new substances formed as a result of a chemical reaction. They are typically written on the right side of a chemical equation.
List some evidence that a chemical reaction has occurred.
Evidence of a chemical reaction can include:
Formation of a gas (bubbles)
Formation of a solid (precipitate)
Change in temperature (heat released or absorbed)
Change in color
Emission of light or sound

What is the Law of Conservation of Mass in chemical reactions?
The Law of Conservation of Mass states that during any chemical reaction, matter cannot be created or destroyed. The total mass of the reactants must equal the total mass of the products.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that releases energy, usually in the form of heat or light, to its surroundings.
What is an endothermic reaction?
An endothermic reaction is a chemical reaction that absorbs energy, usually in the form of heat, from its surroundings

What is an open system in terms of chemical reactions?
An open system is one where both matter and energy can be exchanged with its surroundings. For example, a reaction in an open beaker.
What is a closed system in terms of chemical reactions?
A closed system is one where energy can be exchanged with its surroundings, but matter cannot. For example, a reaction in a sealed flask.
