Oh, my teacher did not say that the forces were all equal to zero, just that the applied force was equal to zero.
I don't know if this helps, but this is a lab and we were increasing the angle of a ramp until our mass (a piece of wood with a few weights attached) moved down the ramp. Yeah...
Yes, Ffs was meant to represent static friction. I was unaware that static friction meant that all forces equaled zero.
Fnet=0 so Fll-Ffs
0=1.144-Ffa
-1.144=-Ffa
Ffa=1.14N
Homework Statement
Draw an Fn picture and find Ffs.
mass=.26kg
θ=26.1
Fa= 0
Homework Equations
Fll= mgsinθ
Fnet= sum of all forces parallel to ramp
Fnet= ma
The Attempt at a Solution
I have the picture drawn but I don't know how to find friction.
In the first part of your problem you say that you are looking for Z2H5, but then in your work you are using O. I am not quite sure where you are getting that from.
My chem teacher briefly showed me how to do it and did not have time to check my answer. I am 99% positive that I got the...
I was looking at a problem like this in another thread. I am only in my first quarter of AP Chem and we have not worked with problems like this yet. Here is the thread https://www.physicsforums.com/showthread.php?t=261923". These problems have me fired up now! I'm going to class early today...
You don't need to use N2 or O2 because they are together in the compound (this rule only applies when they are used as separate elements), so you should only use N and O.
Before you can find the molecular formula, you need to find the empirical formula. In order to do this, you must find the...
You're welcome!
To answer your second question- the moles of H2O could be affected, but it would depend on what the question is asking you to do. If you post the entire question, I might be of more assistance.
