Question

Give one example each of displacement decomposition and combination reaction with explanation

Answer 1

Na2 + AgCl ------------ NaCl + Ag this a example of displacement reaction ................

Mg+ O2 ----------------2MgO .....this a example of combination reaction ......
CaCo3. heat. _________Ca + Co3 ...this a example of decomposition reaction...
EXPLANATION .

1} In above displacement reaction ....we can see that ..Ag( silver ) AND NaCl after reaction Ag where displace from Cl .......

2) In combinations reaction. ..we can see that .......Mg (magnesium) and O2(oxygen ) react reach other to form MgO2 (magnesium oxide) is form which mean's two elements react each other to form single compound ..

3) In decomposition reaction ...we can see that. first CaCO3( calcium carbonate) after heating we see calcium and carbonate are decompose .......It's mean's compound element get decompose


2)
