Front

What is the word equation for combustion?

Back

Fuel + Oxygen -> Water + Carbon Dioxide

Front

Is calcium oxidized or reduced in the reaction 2 CaO -> 2 Ca + O2?

Back

Calcium is reduced.

Front

How does a solution become supersaturated?

Back

By dissolving more solute than you should be able to.

Front

What do oxidation-reduction reactions compete for?

Back

Electrons.

Front

In the reaction Zn + H2O -> ZnO2 + H2, which element is oxidized?

Back

Zn (0) is oxidized.

Front

Define combustion in chemistry.

Back

A chemical reaction that typically involves a fuel and oxygen, producing heat and light.

Front

What is oxidation?

Back

The loss of electrons or an increase in oxidation state by a molecule, atom, or ion.

Front

What is reduction?

Back

The gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as an oxidizing agent, facilitating the combustion process.
