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.

Answer:
The sentence that is correctly punctuated is the following one: "Let's get going," Ginnie shouted, "it's getting dark!"
Explanation:
The sentence above is a direct quotation. Quotation marks are for when you want to include someone else's words in your own writing. What is more, direct quotations contain a quote in which you report the exact words used.
In this case, the quote has been split. When you split a quote to introduce a parenthetical, you shouldn't capitalize the second part of the quote example: (it's getting dark!"). Also, the exclamation mark goes inside the quote because it applies to the quoted material, not to the whole sentence. For these reasons, the sentence chosen is the one that is correctly punctuated.
