We ban all bots.To use Hess' Law, you need to do algebra on the given eqns to get the desired eqns.
Unless the given eqns are correct, it is doomed. Pls check carefully.
I don't know whether you are just typing them here incorrectly (easy enough), or you aren't sure yourself. Acellus AP Chemistry is taught by Dr. James Chapman and Greg Spiegel. They come to understand the importance of a lab notebook. The lab for this unit is on thin layer chromatography.
volume calorimetry, and enthalpy. They study exothermic and endothermic reactions, constant pressure calorimetry, and Hess's law. Further, they .
9) Use Hess’s Law and your answers from questions 7 and 8 (and research questions ) to calculate the heat of reaction for the burning of magnesium in oxygen. 10) Look up the heat of formation of magnesium oxide in your textbook.
Hess’s Law Labs By Austin Lee, Alayna Baron, Lily Zmachinski Introduction - In order to calculate the enthalpy change for the combustion of magnesium oxide (Mg (s) +1/2O 2(g) > MgO (s)), we used a coffee cup calorimeter to calculate the enthalpies of of two separate reactions.
Watch video · AP Chemistry free response 7. other reaction seems to be made up of similar things, your brain should immediately say, hey, maybe this is a Hess's Law problem. Hess's Law. And all Hess's Law says is that if a reaction is the sum of two or more other reactions, then the change in enthalpy of this reaction is going to be the sum of the.
Mar 03, · I did a bunch of calculations and I got that q of water is a negative number. I'm then supposed to use this negative number in the calculation for the heat capacity of the calorimeter: Specific heat capacity of the calorimeter = q of water/(T of mix - T of initial) I got a negative number.
does it make any show more I did a bunch of Status: Resolved.
