Single displacement reaction
A single-displacement reaction is where one element appears to move out of one compound and into another. This is usually written as
A + BX → AX + B
This will occur if A is more reactive than B.
A and B may not have the same change when ions are formed therefore some balancing of the equation may be necessary. For example the reaction between calcium Chloride (CaCl2) and Sodium (Na) forms Calcium (Ca) and sodium chloride (NaCl)
CaCl2 + 2Na → Ca + 2NaCl
