Question

scientists use different types of models to study the composition of matter and how matter behaves. three different types of molecular models and their uses are shown. match each type of model with its use.
particle model for water molecules in ice
chemical formula for water
space - filling model for water
shows the relative size and number of atoms in a water molecule and how the atoms in a water molecule and how the atoms are joined to one another
shows how several water molecules are oriented in space relative to one another in addition to showing relative size and number of atoms in a molecule
represents only the type and number of atoms in a water molecule; used to represent substances in a chemical equation

Explanation:

• The space - filling model shows the relative size and number of atoms in a water molecule and how the atoms are joined to one another.
• The particle model for water molecules in ice shows how several water molecules are oriented in space relative to one another in addition to showing relative size and number of atoms in a molecule.
• The chemical formula \(H_2O\) represents only the type and number of atoms in a water molecule; used to represent substances in a chemical equation.

Answer:

1. space - filling model
2. particle model for water molecules in ice
3. chemical formula \(H_2O\)
