When coach kwan notices that a player is getting tired, she takes out the tired player and substitutes a fresh player. which type of chemical reaction does this best model? replacement decomposition synthesis oxidation

replacement

Explanation:

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.

Na + HCl → NaCl    

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
