Answer:
A. Bubbles formed
Explanation:
When a student added a piece of limestone to a solution of hydrochloric acid, bubbles are formed.
The bubbles are as a result of the CO2 gas that is formed.
Below is the reaction:
CaCO3+2HCl → CO2+H2O + Ca++ + 2Cl-
From the left hand side, we can see that the reaction is with limestone and hydrochloric acid. Their reaction forms carbon dioxide gas (CO2), water (H2O), dissolved calcium (Ca++) and dissolved chlorine (Cl-) on the right hand side.
With due observation, bubbles will be seen evolving from the reaction. These bubbles formed is the carbon dioxide gas which reveals that a reaction is taking place.

Option E. One quality of a good research question is that it provides specific details of the context.
<u>Explanation:</u>
It is very important that the person who is required to answer the question understands it well otherwise the answer will not help the researcher. For example, if the researcher is researching ‘teenagers’, the question needs to specify what aspect is being referred to. Is it their behaviour with peers, with teachers or with parents or is it their attitude towards particular things?
For instance, a research question can be framed as :
What is the attitude of teenagers towards their peers in school? Unless the question is detailed well, the answer will not meet the expectations of the researcher.
