Question
Write the correct balanced equation for each of the following reactions. Include the proper subscripts to identify the state of matter all reactants products. Write the type of reaction on the blank line. solid aluminum reacts with oxygen gas to form solid aluminum oxide type of reaction: aqueous solutions of calcium chloride and sodium phosphate react to form solid calcium phosphate and aqueous sodium chloride type of reaction: solid magnesium carbonate decomposes into solid magnesium oxide and carbon dioxide gas type of reaction: solid iron and aqueous copper (II) bromide react to form solid copper and aqueous iron(II) bromide type of reaction:Explanation / Answer
2(a)
Strong heating is required to make aluminium powder burn in oxygen. Much heat is given out during the reaction and a white powder is formed.
aluminium + oxygen----->luminium oxide
4Al(s) + 3O2(g) -----> 2Al2O3(s)
Type of reaction: Endothermic reaction (Addition reaction)
(b)3CaCl2(aq)+2Na3PO4(aq)-------->Ca3(PO4)2(s)+6NaCl
Type of reaction: Precipitation reaction
(c)MgCO3(s)-------> MgO(s) + CO2(g)
Type of reaction: Decomposition
(d)
Fe(s)+CuBr2(aq)--------> Cu(s)+FeBr2(aq)
Type of reaction: Displacement reaction(Redox reaction)
