Unit 6.3-Test Review (Part 2)

Front

What are the products in a chemical reaction?

Back

The substances formed as a result of a chemical reaction, typically found on the right side of the chemical equation.

Front

What are reactants in a chemical reaction?

Back

The starting substances that undergo a chemical change, typically found on the left side of the chemical equation.

Front

What does the Law of Conservation of Matter state?

Back

Matter cannot be created or destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

In a closed system, how does the mass of products compare to the mass of reactants?

Back

The mass remains the same; it is conserved.

Front

What happens to the mass of products in an open system?

Back

The measurable mass might decrease because gases produced can escape, but the actual mass remains the same.

Front

What is a closed system in the context of chemical reactions?

Back

A system where no matter can enter or leave, allowing for the conservation of mass.

Front

What is an open system in the context of chemical reactions?

Back

A system where matter can enter or leave, potentially affecting the measurable mass of products.

Front

How can you demonstrate the Law of Conservation of Matter with a chemical equation?

Back

By showing that the total mass of reactants equals the total mass of products in a balanced chemical equation.

Front

What is the significance of balancing a chemical equation?

Back

Balancing ensures that the number of atoms for each element is the same on both sides, reflecting the conservation of mass.

Front

What is a chemical equation?

Back

A symbolic representation of a chemical reaction, showing the reactants and products and their quantities.
