Chemistry Unit 7 Lesson 1: Chemical Equations Practice

Front

What is a chemical equation?

Back

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

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 formed as a result of a chemical reaction.

Front

What does the law of conservation of mass state?

Back

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

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction, reflecting the ratio in which they react and are produced.

Front

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

Back

A word equation describes a chemical reaction using the names of the reactants and products, while a chemical equation uses chemical formulas to represent them.

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the attraction between positively and negatively charged ions.

Front

What is the formula for Strontium phosphate?

Back

Front

What does (aq) signify in a chemical equation?

Back

(aq) indicates that a substance is dissolved in water, meaning it is in an aqueous solution.
