Hi, but how do you make an quantitative experiment to test that? Also, how about the polar and non-polar stuff? it seems harder to test whether a covalent compound is polar or not.

So...how do you carry out an experiment to test if these unknowns are covalent (polar or non-polar) or ionic? Unknowns: C6H12O6 --NaCl --CH4N20 --C6H8O7

Is it calculus-based? Do you apply Calculus in IB Physics?

What are the textbooks that you use for IB Physics? IBH Physics? Or if you're not doing IB/H Physics you can still recommend textbooks for AP Physics B or AP Physics C. Or even better, you can recommend general introductory physics textbooks (but I'd prefer first and second year university physics textbooks). The purpose is that I'm doing extensive research on general physics in preparation for the IB Physics. Thanks for any recommendation.

Thanks a lot. This is the kind of answer I've been expecting to see.

So why is heat a path function ? Is it because when you use different method of changing temperature, the heat will be different? The same concept applies for work? Now comes the ultimate question again: How is it possible that two path functions (heat and work, for example) add up to a state function (change in internal energy)? The formula is: (delta)E = q + w. I've looked at it for several times but couldn't understand how it is possible for two path functions to become one state function.

I'm going through this stuff in Thermochemistry.

No, it's not. It's more of a thermochemistry question.

How is it possible that two path functions (heat and work, for example) add up to a state function (change in internal energy)? Why is energy a state function? Why is heat a path function? Why is work a path function? Many thanks.

Good question. Maybe it just compresses your heart and prevents it from beating normally and slows down the pace of beating and then the heart gets weaker and weaker and then it dies out?

So it is used for punishment--and perhaps also for suicide. What is the minimum lethal dose usage for it?

I knew that! I was quite surprised that urza said that it's used as bombs...I was like this

How can it be used to make bombs? What is the formula for creating explosives with KCl?

How many uses does the ionic compound Potassium Chloride (KCl) have?
