Answer:
START and STOP, ReAcTanTS means START, PrOducTS means STOP
Explanation:
1. We find words 'STOP' and 'START'.
2. Let's take a look at the word 'ReAcTanTS'. Enumerate the capital letters from 1 to 5 from left to right, that is,
'1': R,
'2': A,
'3': T,
'4': T,
'5': S.
Notice that if we take a combination of 54213, we obtain a word 'start'. This has, of course, a chemical application. Reactants are the ones we start with in a chemical reaction.
3. Let's take a look at the word 'PrOducTS'. Enumerate the capital letters from 1 to 4 from left to right, that is:
'1': P,
'2': O,
'3': T,
'4': S.
Notice that if we take a combination of 4321, we obtain a word 'stop'. Similarly to the previous word, it also has a direct relationship to the chemical context. Products are formed in a chemical reaction when reactants combine. This is the point where reaction comes to and end and eventually stops if it's a typical one-sided reaction.
