Which reactions are double replacement? Why?

1) 3Fe(OH)2 + 2H3PO4 → Fe3(PO4)2 + 6HOH

2) Pb(NO3)2 + 2KI → PbI2 + 2KNO3

3) 2NH4OH(aq) + H2S(aq) → (NH4)2S(aq) + 2H2O(l)

4) 2 HCl + Zn → ZnCl2 + H2

Which reactions are neutralization of acid and base? How do you know? Neutralization reactions 1. are a type of double replacement reaction 2. reactants must be ACID and BASE What are the products?

answers: double replacement reactions: # 1,2,3 neutralization reactions: #1 and 3

Neutralization reactions 1. are a type of double replacement reaction 2. reactants must be ACID and BASE 3. the products are WATER and SALT. (an ionic compound)

NaOH + HCl H2O + NaCl base + acid water + salt

another example:

Ca(OH)2 + H2SO4 2H2O + CaSO4

Write the reactant formulas, then predict the products and balance

Zinc hydroxide and sulfuric acid →

potassium hydroxide + chlorous acid →

carbonic acid and strontium hydroxide è

Answers: Zn(OH)2 + H2SO4→ ZnSO4 + 2HOH(l)

KOH + HClO2 → KClO2(aq) + HOH(l)

H2CO3 + Sr(OH)2 + → SrCO3 + 2HOH(l)

more practice

iron(II) hydroxide + phosphoric acid →

ammonium hydroxide+ hydrosulfuric acid→

answers:

3Fe(OH)2 + 2H3PO4 → Fe3(PO4)2 + 6HOH(l)

2NH4OH + H2S →/(NH4)2S + 2HOH(l)
