2. lithium hydroxide sodium chromate

3. zinc acetate cesium hydroxide

4. potassium sulfide is reacted with nitric acid

5. strontium hydroxide ammonium sulfide

6. sodium nitrate is reacted with hydrochloric acid

7. carbon dioxide gas is reacted with solid potassium oxide

8. solid magnesium oxide is reacted with hydrochloric acid

9. ammonium carbonate potassium bromide

10. oxalic acid (.1 M) reacts with an equal volume of cesium hydroxide (.1 M)

11. silver nitrate sodium chromate

Answer 1

MgO + SO3 >> MgSO4

2 LiOH + Na2CrO4 >> 2 NaOH + Li2CrO4

Zn(CH3COO)2 + 2 CsOH >> Zn(OH)2 + 2 CH3COOCs

K2S + 2 HNO3 >> 2 KNO3 + H2S

Sr(OH)2 + (NH4)2S >> SrS + 2 NH4OH

NaNO3 + HCl >> HNO3 + NaCl

CO2 + K2O>> K2CO3

MgO + 2 HCl >> MgCl2 + H2O

(NH4)2CO3 + 2 KBr >> K2CO3 + 2NH4Br

H2C2O4 + CsOH >> HCsC2O4 + H2O

2 AgNO3 + Na2CrO4 >> Ag2CrO4 + 2 NaNO3
