Question

question 9. directions: drag and drop the correct answer choice to each answer blank. or, touch the answer choice followed by the answer blank. move the correct answer to each box. a student mixes two unknown solutions together and writes down observations. the student thinks a chemical change is occurring because when the two solutions mix, the student observes an unexpected change in color. therefore, the student claims that a new substance blank formed. (answer choices: was not, was, volume, color, (clear answer))

Explanation:

To determine the correct answers, we analyze the context:

1. For the first blank (about the change in what was observed), a color change is an indicator of a chemical change, while a volume change is a physical change. So the first blank should be "color".
2. For the second blank (whether a new substance was formed), a chemical change implies a new substance is formed, so the second blank should be "was".

Answer:

First blank: color
Second blank: was
