Chemical reaction can be classified into various forms like decomposition reaction, replacement reaction, oxidation reaction, combustion reaction , synthesis reaction etc.
The best model that fits this scenario of substituting a player on the pitch is the replacement reaction.
A replacement reaction occurs when element switched ion in a compound. A replacement reaction occurs when element displace another element in it compound. The very reactive non metal element will displace another less reactive non metal element in it compound while a more reactive metal element will replace a less reactive metal element from it compound. An example is when fluorine replace Bromine in it compound or when Na replace hydrogen in it compound.
Karen Horney , <em>who was one of the earliest psychologists to champion women's issues, suggested that personality develops in the context of social relationships and depends particularly on the relationship between parents and child and how well the child's needs are met.</em>
