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 organizational pattern being used is A. definition.
Explanation:
This question is confusing to many people - you will actually find several claiming the answer is letter C, classification, which it is NOT. As a matter of fact, we just need to take a look at the beginning of the excerpt to identify the pattern.
The author says, "Gravity is the source of a black hole’s super pull." What is she doing here? She is defining gravity, explaining what it is, its meaning. The rest of the excerpt is a continuation of that pattern. She is offering further details to make the definition more complete. A definition pattern is easily identifiable because it often uses terms such as: <u>is, means, refers to, is called, is defined as, entails, is characterized by.</u>
