Investigation 6 Chemistry Review

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light. It typically involves the burning of hydrocarbons, resulting in carbon dioxide and water.

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation. Adjust coefficients in front of compounds as necessary.

Front

What are the products of the reaction between AgNO3 and NaCl?

Back

The products are AgCl (silver chloride) and NaNO3 (sodium nitrate).

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in a chemical reaction and remain unchanged in the solution.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction involves two or more reactants combining to form a single product, while a decomposition reaction involves a single compound breaking down into two or more products.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the law of conservation of mass?

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

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces (ionic bonds). It typically forms between metals and nonmetals.

Front

What is the difference between an endothermic and exothermic reaction?

Back

An endothermic reaction absorbs heat from the surroundings, while an exothermic reaction releases heat.
