Back

Nitrogen dioxide reacts with water.

Front

What must one consult to determine whether a single replacement reaction will occur?

Back

The activity series.

Front

What type of reaction is represented by the equation 3Mg + N₂ → Mg₃N₂?

Back

Synthesis Reaction.

Front

Which compound is formed first in the atmosphere during a lightning strike?

Back

Nitric oxide (NO).

Front

Define a combustion reaction.

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

Front

What is the activity series used for in chemistry?

Back

It is used to predict whether a single replacement reaction will occur based on the reactivity of the elements.

Front

What is the chemical formula for nitric acid?

Back

HNO₃.

Front

What is the primary product of the combustion of methane (CH₄)?

Back

Carbon dioxide (CO₂) and water (H₂O).

Front

Explain the role of lightning in the formation of nitrogen oxides in the atmosphere.

Back

Lightning provides the energy needed to break nitrogen molecules (N₂) apart, allowing them to react with oxygen to form nitrogen oxides.
