Question

a scientist had two substances. one was a yellow liquid. the other was a colorless liquid. the scientist added a few drops of the yellow liquid to the colorless liquid. a red solid formed.
what most likely happened when the scientist mixed the two liquids?
a. a new substance with properties identical to the yellow liquid was formed.
b. the two substances stayed the same and no new substances were formed.
c. a new substance with properties identical to the colorless liquid was formed.
d. a new substance with properties different from either of the liquids was formed.

Explanation:

Step1: Analyze chemical reaction result

When two substances react and a new - colored solid (red solid) forms from a yellow liquid and a colorless liquid, it indicates a chemical change.

Step2: Evaluate each option

A new substance with properties different from the reactants is formed in a chemical reaction. Option A is wrong as the new substance is a red solid, not a yellow - like substance. Option B is incorrect because a red solid is formed, meaning new substances are formed. Option C is wrong since the new substance is a red solid, not colorless - like. Option D is correct as the red solid has different properties from the yellow and colorless liquids.

Answer:

D. A new substance with properties different from either of the liquids was formed.
