Question

Which of these scenarios is most likely a chemical reaction?
A. A gas turns into a liquid as it releases energy.
B. A liquid becomes a gas as it absorbs energy.
C. Two white solids are added to a colorless liquid, and a colorless liquid remains.
D. Two colorless liquids are added together, and a colorless liquid and a green solid remain.

Answer 1

Answer:

D. Two, colorless liquids are added together, and a colorless liquid and a green solid remain.

Explanation:

Answer 2

Two, colourless liquids are added together, and a colourless liquid and a green solid remain. Hence, option D is correct.

What is a chemical reaction?

A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products.

In the scenarios mentioned in the question, all are considered under chemical reactions.

● In the first reaction when gas is turned into a liquid and energy is released few molecules get transformed into other compounds and hence chemical change takes place.

● In the second case when two white solids are mixed in a colourless liquid the two white solids get dissolved in the colourless liquid forming a new solution which is a chemical change.

● In the third case two colourless liquids are added together and a colourless liquid and a green solid are the products of IT in this case also a chemical reaction takes place resulting in the formation of a green colour Residue.

Two, colourless liquids are added together, and a colourless liquid and a green solid remain. Hence, option D is correct.
