Unit 3 Part 2 Review

Front

What is a limiting reagent in a chemical reaction?

Back

The limiting reagent is the substance that is completely consumed first in a chemical reaction, limiting the amount of product formed.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products.

Front

What are reactants in a chemical equation?

Back

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

Front

What are products in a chemical equation?

Back

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

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the formula for Sulfuric Acid?

Back

H₂SO₄

Front

What is the coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What is the difference between a chemical formula and a chemical equation?

Back

A chemical formula represents the composition of a substance, while a chemical equation shows the reactants and products in a chemical reaction.

Front

What does it mean to say a reaction is balanced?

Back

A balanced reaction means that the number of atoms for each element is the same on both sides of the equation.

Front

What is the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the relative amounts of reactants and products involved in the reaction.
