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 (h₂o), space - filling model for water. 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; shows the relative size and number of atoms in a water molecule and how the atoms are joined to one another; represents only the type and number of atoms in a water molecule, used to represent substances in a chemical equation

Explanation:

• For the first description: The particle model of water molecules in ice shows multiple molecules' spatial orientation along with atom size and number info, so it matches.
• For the second description: The space - filling model shows the relative size, number of atoms in a molecule and their bonding (how they are joined), so it matches the space - filling model for water.
• For the third description: A chemical formula like \(H_2O\) only shows the type (H, O) and number (2 H, 1 O) of atoms and is used in chemical equations, so it matches the chemical formula for water.

Answer:

1. "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" → "particle model for water molecules in ice"
2. "shows the relative size and number of atoms in a water molecule and how the atoms are joined to one another" → "space - filling model for water"
3. "represents only the type and number of atoms in a water molecule, used to represent substances in a chemical equation" → "chemical formula for water"
