The freezing point of a certain alcohol is -114 celcius. The freezing point of a certain acid is -42 celcius. What is the difference between the freezing point of alcohol and acid?

Answer

-72

Step-by-step explanation:

The difference between each can be achieved by subtracting -42 (the freezing point of the acid) to -114 (the freezing point of the alcohol).

From there, we get the equation -114 - -42, which then leads to equal -72.

A way I check this is that I go back and add our answer to the lowest term, which becomes -42 + -72, which does, in fact, equal -114.

So your answer is -72.
