1. Name 3 insoluable compounds, each with a different anion

2. Name 3 strong acids, only 1 can be from group 17
3. Name 3 strong bases, all from different groups

1. To find 3 insoluble compounds with different anions, we need to consider the solubility rules. According to these rules, compounds containing certain anions tend to be insoluble in water. Here are three examples:

- Silver chloride (AgCl): Silver chloride is insoluble in water. Compounds containing chloride ions, such as most silver compounds, are typically insoluble.
- Barium sulfate (BaSO4): Barium sulfate is not soluble in water. Compounds containing sulfate ions, except for those of Group 1 metals and some ammonium compounds, are generally insoluble.
- Lead(II) carbonate (PbCO3): Lead(II) carbonate is also insoluble. Carbonates, except those of Group 1 metals and ammonium, are typically insoluble as well.

2. Three examples of strong acids, with only one from Group 17 (the halogens), are:

- Hydrochloric acid (HCl): Hydrochloric acid is a strong acid and belongs to Group 17 (chlorine).
- Sulfuric acid (H2SO4): Sulfuric acid is another strong acid. It is not from Group 17 but contains sulfur.
- Nitric acid (HNO3): Nitric acid is also a strong acid, and it is not from Group 17 but contains nitrogen.

3. Three examples of strong bases from different groups are:

- Sodium hydroxide (NaOH): Sodium hydroxide is a strong base and belongs to Group 1 (alkali metals).
- Calcium hydroxide (Ca(OH)2): Calcium hydroxide is another strong base and is not from Group 1. It contains calcium, which is an alkaline earth metal (Group 2).
- Aluminum hydroxide (Al(OH)3): Aluminum hydroxide is also a strong base but is not from either Group 1 or Group 2. It contains aluminum, which belongs to Group 13.

Remember, strong acids and bases are substances that dissociate completely in water, producing a high concentration of hydrogen ions (H+) or hydroxide ions (OH-), respectively.
