Question

Are the top answers correct? if so, what do I write for the bottom part?

Fall 2109 CHE 151-01 Exam 2 Chapter 4-6 Question 7 (10 Points) Identify the type of reaction below 1. Pb + Feso. → PbSO. + Fe 2. CaCO > CaO + CO2 3. P. + 302 → 2 P.0, 4. 2 RbNO, + BeF: → Be(NO3)2 + 2 RbF 5. 2 AgNO3 + Cu → Cu(NO.) + 2 Ag 6. C3H6O + 4 O2 + 3 CO2 + 3 H2O 7. 2 CsHs + Fe → Fe(CsHs) 8. 2 Mglz + Mn(SO3)2 → 2 MgSO; + Mnla 9. Os + O2 10.2 NO2 → 2 O2 + N2 Reaction Type Sinale displacement Reaction Type decomposition Reaction Type Sunthesis Reaction Type double chaplacement Reaction Type Single displacement Reaction Type combustion Reaction Type Synthesis Reaction Type double displacement Reaction Type decomposition Reaction Type decomposition Question 8 (10 Points) For the even numbered reactions above, explain why you chose the reaction type you did? 10) RAFW/CHE/151-01/Exam_1_Chapters_4 and 5

Answer 1

All the top answers are correct!

2) In this 1 compound which is CaCo3 is split into 2 parts, which means it is decomposed. Thus the reaction decomposition.

4) In this 2 compounds are involved and are paired in some way after reaction both cations exchanged their anions. Thus called double displacement reaction.

6) When any compound is burnt in oxygen or set to react with only oxygen then it is called combustion or oxidation reaction.

8) Same explanation as 4.
