Answer 1

I can’t see the equations for Questions 1–3 — please paste the reaction equations (or upload the images) and I’ll identify their types. Meanwhile, I can answer the rest:

Question 4
- Answer: b (Double displacement)
- Reason: two ionic compounds exchange ions (KI + MgS → MgI2 + K2S).

Question 5
- Blank 1: endothermic
- Blank 2: cold
- Reason: endothermic reactions absorb energy from the surroundings, so the surroundings feel colder.

Question 6
- Blank 1: exothermic
- Blank 2: hot
- Reason: exothermic reactions release energy to the surroundings, so the surroundings feel hotter.

If you post the reactions for Q1–Q3 I’ll classify those too.
