What is a chemical reaction?

Back

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

Front

What does it mean to balance a chemical equation?

Back

To ensure that the number of atoms of each element is the same on both sides of the equation, reflecting the conservation of mass.

Front

What are coefficients in a chemical equation?

Back

Numbers placed before compounds in a chemical equation to indicate the number of molecules or moles of that substance.

Front

What is a word equation?

Back

A representation of a chemical reaction using the names of the reactants and products instead of their chemical formulas.

Front

How do you balance the equation: Al + Cu(NO3)2 → Cu + Al(NO3)3?

Back

2Al + 3Cu(NO3)2 → 3Cu + 2Al(NO3)3.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is a reactant?

Back

A substance that undergoes a chemical change in a reaction.

Front

What is a product?

Back

A substance that is formed as a result of a chemical reaction.

Front

What is the difference between a single replacement reaction and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound. In a double replacement reaction, the ions of two compounds exchange places.

Front

What is the significance of the states of matter in a chemical equation?

Back

The states of matter (solid, liquid, gas, aqueous) indicate the physical form of the reactants and products, which can affect the reaction conditions.
