I thought it was 0.1 as 0.05+0.05=0.1 moles = total moles of reactants.
But I have figured this one out. it says the TOTAL heat capacity is 1100 joules so q=c*∆T = 1100*1.2=1320 Joules. So 1320 Joules for every 0.05 moles formed 1320*1/0.05=26400 Joules
Hi
I have a few questions that I have been working on but I don't get the right answer.
After drawing the Lewis dot structure of HOClO2, pick the incorrect statement of the following.
A. The oxygen bonded to the hydrogen has two lone pairs
B. the oxygens not bonded to hydrogen have three lone...
Homework Statement
The problem was to tell how many hydrogen bonds there are between cytosine and guanine. and I know there are three. http://study.com/cimages/multimages/16/Cytosine_Guanine_base_pair.png
But I think I might be misunderstanding the hydrogen bond concept.
I thought that hydrogen...

Let's say we have a 1.00 L solution containing 3 moles of NaCH3COO and 2 moles of NH4Cl.
These reaction will occur:
CH3COO-+H2O --> CH3COOH + OH- Kb=5.56e-10
NH4++H2O -->NH3+H3O+ Ka=5.56e-10
3 moles of CH3COO- will give 4.08e-5 moles OH-
2 moles of NH4+ will give...
I am trying to get a better understaning of the pH of a solution containing a salt of a weak base and a salt of a weak acid. I know it depends on which equlibrium constant is greater but I am thinking more of what it is that actually happens.
For example let say we have a solution containing...
I am trying to understand the v=f*lambda equation.
I understand that the speed of soundwave is the same throughout the medium.
But let's say I have some kind of source that emits sound waves. If i increase the frequency, will the wavelength automatically decrease as the product of frequency x...
When you draw a free body diagram be careful not draw both forces in a action-reaction pair. In a action-reaction pair the forces don't act on the same body. If you and I both pull the string with equal but opposite forces, I am the body which you apply force to and you are the body I apply...
Newton's thirld law. If you pull a string fixed at the other end it will have the same tension as the if the string is pulled by equal but opposite forces.
Cars A and B have the sama mass.
A and B are traveling at 60 mph toward each other. They have two options: hitting the other car head on, or swerving into a massive concrete wall, also head on. (assume the same amount of KE is lost by your car in both collisions.) Should the drivers hit the...
