Front

What type of reaction is Fe + CuSO4 -> FeSO4 + Cu?

Back

This is a single replacement reaction.

Front

What is the balanced chemical equation for CO + Fe2O3 -> Fe + CO2?

Back

The right ratio of chemicals for the balanced equation is 3,1 -> 2,3.

Front

Multiply: (9.4 x 10^6)(3.2 x 10^5)

Back

The result is 3.008 x 10^12.

Front

Define ionization energy.

Back

Ionization energy is the energy required to remove an electron from an atom or ion.

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.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one reactant breaks down into two or more products.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

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

Back

In a single replacement reaction, one element replaces another in a compound, while in a double replacement reaction, two compounds exchange components.
