Two cups of the same size are filled to the brim with clear liquids. cup a holds water. cup b contains alcohol. your teacher challenges you to figure out which cup holds water. because of your great scientific knowledge, you know that all substances have their own special properties. first, you waft (carefully smell) the two liquids. what property are you checking when you waft?
a) color
b) odor
c) taste
d) texture

Hello there! The correct answer is B) odor.

When you are wafting something, you're checking its smell in a careful way so you don't get harmed by  potentially harmful chemicals. The odor of something is how it smells, or what smell it gives off, making this the correct choice. You can also eliminate A and D since the beginning of the question states that they are two clear liquids, so the color and texture won't differentiate one from the other. As well as this, it would not be C since it isn't  smart to taste test chemicals in a lab, unless your teacher says it's okay.

I hope this helps and have a great day! :)

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
