Question

1 Balance each equation. Paragraph Styles Voice Sensity 2) Indicate the type of reaction by classifying each reaction as single replacement (SR), double replacement (DR), decomposition (), synthesis (S), or combustion (C). 3) Give one sentence explaining how you classified each. 1. Al2(SO4)3 + Ca3(PO4)2 -> AIPO4 + CaSO4 Type of reaction: Why: T 2. NaCIO3 → NaCl + O2

​

Answer 1

1. Double replacement (DR)

2. Decomposition (D)

Further explanation

1. Al2(SO4)3 + Ca3(PO4)2 -> 2AIPO4 + 3CaSO4

Double replacement (DR) : there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

General form :

AB + CD -> AD + CB

2. 2NaCIO3 → 2NaCl + 3O2

Decomposition (D) : Reactant breakdown into simpler ones(reverse of combination)

General form :

AB ---> A + B
