Investigation 7 Test Would the following reactions happen? K+HClarrow square Cu+Fe(C_(2)H_(3)O_(2))_(2)arrow square Zn+FeCO_(3)arrow square Cu+Zn(NO_(3))_(2)arrow square

Let's analyze each reaction step by step to determine if they will happen:1. **Reaction: ** - Potassium (K) is a highly reactive metal and will readily react with hydrochloric acid (HCl). - The products of this reaction are potassium chloride (KCl) and hydrogen gas (H₂). - **Reaction:** 2. **Reaction: ** - Copper (Cu) is less reactive than iron (Fe), so it will not displace iron from iron(II) acetate ( ). - No reaction will occur because copper is below iron in the reactivity series. - **Reaction:** No reaction3. **Reaction: ** - Zinc (Zn) is more reactive than iron (Fe), so it can displace iron from iron(II) carbonate ( ). - The products of this reaction are zinc carbonate ( ) and iron (Fe). - **Reaction:** 4. **Reaction: ** - Copper (Cu) is less reactive than zinc (Zn), so it will not displace zinc from zinc nitrate ( ). - No reaction will occur because copper is below zinc in the reactivity series. - **Reaction:** No reactionIn summary:1. 2.
