Which of the five types of equations will occur for each of these reactants, and what will the products be?

Question

The reactants are:

1) An aquaeous solution of two ionic compounds
2) A single compound
3) Two elements
4) Oxygen and a compound of carbon and hydrogen

Help is greatly appreciated.

Answer 1

1. Double Replacement - product will be cation of one compound and anion of other compound and vice versa
2. Decomposition - product - compound will break down into its elements
3. Synthesis - the two elements will combine together to make 1 compound
4. Combustion - H2O and CO2

Answer 2

1) Double Replacement/Displacement
2) Decompostition
3) Composition/Synthesis/Combination
4) Combustion

Answer 3

1) An example of an aqueous solution of two ionic compounds
K2CrO4(aq) + Ba(NO3)2 (aq) ---> BaCrO4 (s) + 2 KNO3 (aq)
A single compound
Decomposition of H2O to H2 + O
3) Two elements Na + +Cl- ---> NaCl
4)CO2or CO ( carbon monoxyde ) are examples of reaction of oxygen and carbon
