Question
The following to be done for the reactants given: a. Write the chemical equations for the reaction (both reactants and products). b. Balance the equations. c. Identify the types of reactions: synthesis, decomposition, single displacement, double displacement or combustion. d. If the equation is a single or double displacement reaction, determine what is oxidized and reduced. 1. barium iodide and sodium nitrate 2. hydrochloric acid and calcium hydroxide 3. aluminum bromide and magnesium 4. calcium and oxygen gas 5. copper (II) sulfate and lithium
Explanation / Answer
1) BaI2 + 2NaNO3 --------------> 2 NaI + Ba(NO3)2
double decomposition
No change in oxidation states , no oxidation/reduction
2) 2HCl + Ca(OH)2 ---------------> CaCl2 + 2H2O
double decomposition (acid-base neutralization)
No oxidation/reduction took place
3 ) 2AlBr3 + 3Mg --------------> 3 MgBr2 + 2Al
single displacement reaction
Mg is oxidised and AL is reduced
4) 2Ca + O2 -------------> 2 CaO
Synthesis reaction
Ca is oxidised and O is reduced
5) CuSO4 +2 Li --------------> Li2SO4 + Cu
single displacement reaction
Cu is reduced and Li is oxidised
