I will give you two clues just incase:
-Change in temperature-usually when a reaction takes place heat will be absorbed or released which result in a temperature change.-eg: put a piece of sodium in water. you will feel or observe that the temperature is increased
-Change in colour-Some times we see a colour change in the media when a reaction takes
How important each one is depends on what you are learning about a chemical reaction. Hope I helped!

Answer:
(E)-3-hexene treated with bromine to form racemic mixture.
Explanation:
(E)-3-hexene treated with bromine to form (S)−3−bromohexane and (R)−3−bromohexane.
The chemical reaction is as follows.
Answer:
The correct option is: conjugate acid
Explanation:
Bases are the chemical substances that are proton acceptors and electron-pair donors. Therefore, when a base accepts a hydrogen proton from an acid it forms a conjugate acid.
Therefore, conjugate acids are formed when a base accepts a hydrogen proton from an acid. Also, if the base is a weak base then its conjugate acid is strong. Whereas, if the base is a strong base then the conjugate acid is weak.
Yes, when molten candle wax solidifies it is a chemical reaction
<u>Explanation:</u>
Basically Wax is crystalline so once the candle light melts it freezes taking back the solid state to the room temperature.
When the room temperature is below the freezing point, the liquid candle wax, turns into solid state again, therefore this process is called solidification. The process of freezing or solidification is a process when an object turns liquid and freezes back to solid state.
Indeed, Yes, when molten candle wax solidifies it is a chemical reaction
