Reactants VS. Products

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting materials in a chemical reaction that undergo transformation to form products.

Front

What is the role of the yield arrow in a chemical equation?

Back

The yield arrow indicates the direction of the reaction, separating reactants on the left from products on the right.

Front

What is a product in a chemical reaction?

Back

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

Front

How can you identify reactants in a chemical equation?

Back

Reactants are found on the left side of the yield arrow in a chemical equation.

Front

What is an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that releases energy, often in the form of heat.

Front

What is an example of a product formed from burning hydrocarbons?

Back

Carbon dioxide (CO2) is a common product formed from the combustion of hydrocarbons.

Front

What happens to energy during an exergonic reaction?

Back

Energy is released to the surroundings, often resulting in an increase in temperature.

Front

What is the significance of balancing a chemical equation?

Back

Balancing a chemical equation ensures that the law of conservation of mass is upheld, meaning the number of atoms for each element is the same on both sides.

Front

What is the difference between a chemical reaction and a physical change?

Back

A chemical reaction involves the transformation of substances into new products, while a physical change alters the form of a substance without changing its chemical identity.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light.
