<div class="IPBDescription">chem test =\</div> You guys want to help me my chem?
i supposeably havee the worst chem teacher at my college, (UNR, nevada) and i fall asleep everyday in it, i dont have a book, and have a test tomorrow =\ (its chem 121)(i know, i know, it is the easy stuff, but thats for u)...Also i got a 91 on the first test, and figured that this one would be as simple
Here are the essay questions
this is last years test, i jsut need to know how to basically do it
write a balanced molecular equation , complete ionic , net inonic equation for the metatheses reaction that occurs when aqueous solutions of calcium iodide and lead nitrate are mixed. identify spectator ions.
calculate the volume of .500 M Ca(OH)2(sub script/aq) needed to completely with 28 mL .725 M HCl(aq)
a piece of silver of mass 75 g at 80 degree C was placed in a calorimeter that contained 50 g of water at 23.2 degrees C. If the temp of the water rose to 27.6 degree C what is the specific heat capacity of silver? The specific heat capacity of water is 4.184 J x (degrees C) ^-1 x g^-1
write out the electronic structure of BI using condenseed spdf notation.
calc the wavelength of a phonton emitted by a hydrogen atom when an electron makes a transition fromt the sixth to the first principal energy level (n=6 to n=1)
