chemistry
we boiled water in a beaker and put a flask with a small amount of an unknown liquid into the flask then covered it with a lid with a pinhole in it, and we placed this flask in the boiling water bath until the liquid evaporated, then we let it cool and condense.

during an experiment, if not all of a liquid vaporizes, in a flask with a cap with a pinhole. will the reported molecular weight be too high or low? i was thinking too high because the liquid weighs more.

I gave my answer on the question about probability. What's wrong with it? The one about the distributive property, also. I thought that was what he/she meant by "expanding." My bad.

The probability that it's a queen would be 1/13, because there are 4 out of 52 cards in the deck that is a queen. 4/52 simplifies to 1/13. The probability that it's a spade would be 1/4, because there are 13 spades out of the 52 cards in the deck. 13/52 reduces to 1/4...

Okay, hete is how to solve this problem: Since the probability that Alysha will miss is 0.15, that means that it is 15%, right? So, the probability that Alysha will NOT miss is 100 - 15, which is 85%. So the answer is 0.85 Now for Carla. 0.07 = 7%. 100 - 7 = 93%. So the answer...
