To determine the types of the given compounds, we need to classify each based on its chemical formula. Here's a step-by-step evaluation of each compound:
1. Compound: [tex]\( \mathbf{C_{12}H_{22}O_{11}} \)[/tex]
- This formula represents a molecule composed of 12 carbon (C) atoms, 22 hydrogen (H) atoms, and 11 oxygen (O) atoms.
- This type of compound is known as a molecular compound, specifically a sugar (sucrose).
Type: Molecular compound
2. Compound: [tex]\( \mathbf{Mg(OH)_2} \)[/tex]
- This formula includes magnesium (Mg) combined with hydroxide anions (OH).
- The metal (magnesium) forms ions with the hydroxide group, making this an ionic compound, specifically magnesium hydroxide.
Type: Ionic compound
3. Compound: [tex]\( \mathbf{H_2O} \)[/tex]
- This simple formula constitutes 2 hydrogen (H) atoms and 1 oxygen (O) atom.
- This is a molecular compound, known commonly as water.
Type: Molecular compound
4. Compound: [tex]\( \mathbf{Cu_3Zn_2} \)[/tex]
- The formula consists of copper (Cu) and zinc (Zn) atoms without clear ionic or covalent bonds.
- Such a composition indicates a metallic alloy, specifically brass.
Type: Metallic alloy
5. Compound: [tex]\( \mathbf{Au} \)[/tex]
- This formula includes just one element, gold (Au).
- Being a single element, it is classified simply as an element.
Type: Element
To summarize, the classifications of the given compounds are as follows:
- [tex]\( \mathbf{C_{12}H_{22}O_{11}} \)[/tex]: Molecular compound
- [tex]\( \mathbf{Mg(OH)_2} \)[/tex]: Ionic compound
- [tex]\( \mathbf{H_2O} \)[/tex]: Molecular compound
- [tex]\( \mathbf{Cu_3Zn_2} \)[/tex]: Metallic alloy
- [tex]\( \mathbf{Au} \)[/tex]: Element
