What is an inverse relationship?

Back

An inverse relationship is a type of correlation where one variable increases as the other decreases. For example, as age increases, the number of push-ups one can do may decrease.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a chemical reaction in which two or more simple substances combine to form a more complex product. Example: 4 Fe + 3 O2 → 2 Fe2O3.

Front

Which state of matter has the strongest atomic attractions?

Back

Solids have the strongest attractions between their atoms, followed by liquids, and then gases.

Front

What is the basic structure of a single replacement reaction?

Back

The basic structure of a single replacement reaction is A + BC → AC + B.

Front

What does the symbol Δ represent in chemistry?

Back

The symbol Δ represents a change in a quantity, commonly used to denote change in heat (ΔH).

Front

What is a direct relationship?

Back

A direct relationship is a correlation where both variables increase or decrease together. For example, as temperature increases, the rate of a chemical reaction may also increase.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2 O2 → CO2 + 2 H2O.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 2 H2O → 2 H2 + O2.

Front

What is the difference between solids, liquids, and gases in terms of atomic attraction?

Back

Solids have strong atomic attractions, liquids have moderate attractions, and gases have weak attractions between their atoms.

Front

What is the formula for a double replacement reaction?

Back

The formula for a double replacement reaction is AB + CD → AD + CB.
