HI

What type of reaction is the reaction between P₄O₁₀+C P₄+CO?

I said it will be both a :

(1) Redox Reaction and a (2) Thermal Decomposition reaction.

Am I right ?

Hi

I'm having trouble with a few questions about classifying the following reaction types.

1. Reaction: BaCl₂(aq) + Na₂(aq)  BaSO₄(s) + NaCl(aq)
My answer: It's a Precipitation reaction as well as a redox reaction.

2. Reaction: Zn(s) + 2HCl(aq)  ZnCl₂(aq) + H₂(g)
My answer: Single Replacement reaction and Redox reaction

3. Reaction: Na₂CO₃(aq) + 2HCl(aq)  2NaCl(aq) + H₂O(l) + CO₂(g)
My Answer: Double Displacement Reaction and Decomposition Reaction

Reaction 4: CuSO₄(aq) + 2NaOH(aq)  Na₂SO₄(aq) + Cu(OH)₂(s)
My Answer: Double Displacement reaction and Precipitation Reaction

Reaction 5: Cu(OH)₂(s) + H₂SO₄  2H₂O(l) + CuSO₄(aq)
My Answer: Acid-Base neutralisation reaction and double displacement reaction

Reaction 6: Zn(s) + CuSO₄(aq)  :rarrow:ZnSO₄(aq) + Cu(s)
My Answer: Precipitation Reaction, Single replacement reaction and redox reaction

I'm very unsure whether I am right or wrong, can someone please verify.
