What type of reaction is the generic equation a + bc → ac + b

(a) single displacement
(b) decomposition
(c) double-displacement
(d) synthesis/combination
(e) none of the above

A

Explanation:

The reaction represented below

A + BC → AC + B

is a single displacement reaction. This type of reaction involves a free element reacting with a compound and replacing another element in the compound due to the fact that its more reactive than the element present in the compound.

In the reaction above A displaces element B from compound BC.

double displacement reaction involves the switch of ions in two compounds that react together. Option A is correct.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
