When 0.500 g of an unknown compound was dissolved in 15.0 g benzene, the freezing point depression was determined to be 0320C . The molar mass of the unknown compound is ? g/mol. (The freezing point depression constant for benzene is 512C kgmol .
? g of glucose C6H12O6 must be dissolved in 400 g of water to give a solution that is 0.258 m.
A solution is made by mixing 25.0 mL of toluene C6H5CH3 d=0867gmL with 135.0 mL of benzene C6H6 d=0874gmL . Assuming that the volumes add upon mixing, the molarity (M) and molality (m) of the toluene are how would i start this problem?
Is the solvation of borax in water an exothermic or endothermic process? i am thinking the it is endothermic...is that right?
i need to know if there are any technologies that were developed from the knowledge of static electricity. I also need to know what kinds of jobs people have that use these technologies. thanks
Two charges 10uC (point A) and -10uC (point B) are placed 10cm from each other. Find the electric field at a point P perpendicular bisector of AB at a distance 12cm from the middle. Can someone get me started on this one? I'd appreciate any help. Thanks
You could put:Women have been a great contributor to American culture.
I will go with Ms. Sue's answer. It could still be either way around.
Two charges (+4C and -3C)are separated by .00002m. What is the electrostatic force and its direction? Using Coulomb's law, I arrived at 2.696 x 10^20 J. Would the direction be said to be "towards the positive charge"? Is this correct? Thanks
I have a question about my math. A cat falls in a hole at 12:00.The hole is 6ft deep. He climbs out at two feet per-minute,falling back one foot.What Time will the cat get out of the hole?
I need a version I can understand of The Prioress' Portrait from the General Prologue to the Canterbury Tales.
does anyone know a version of Twa Corbies that I can actually understand?
Was Chaucer the first author to use a frame story?
Would Canterbury be considered in the Southeast part of England?
What does "almost everything in this isle enjoys immunity to poison" - Bede mean? Does it have something to do with Ireland?
Since the imagination of evil encourages us to do real evil, how should we react to accounts from the media or elsewhere about monstrous evil in our neighborhood or elsewhere in the world?
What ethic of interpretation is imposed on us by the fact that monstrous ritual is fantasy?
Jackies kitten is stuck on the window sill of her neighbors house. The window is 2.8m above the ground. The base of the ladder must be 0.7m away from the house and the ladder must extend 1m above the window sill. Will she be able to rescue the kitten, explain how..
If I have info. that fits into distinct catergories and want to compare totals what kind of graph should I use? A bar graph?
40(t+1.5)=60x t 2/3(t+1.5)= T

So what does this have to do with helping astronomers understand the development of the solar system? When the Earth rotates on its axis, is this part of angular momentum being conserved? Does angular momentum show the astronomers how the earth and other planets rotate?

help me predict the product sodium iodide-> You have only one reactant. Of course we could write sodium iodide ==> sodium iodide.
