Hello Vickson,
So it would change the scenario if the events were independent. Then if events A, B, C and D could occur without the other(s) happening the 2nd post would be correct?
I think I will get back to this after I familiarize myself with set algebra.
Thanks for your inspection of...
Hello Vickson,
Thank you for your reminder; Using P(AnB)= P(A)*P(B) I believe that they can be solved as below? (some expressions were substituted backwards)
1. P(AnB)= P(A)P(B) [solved]
2. P((AUB)nC) = [P(A)+P(B)-P(AnB)]*P(C)
= [P(A) + P(B) - P(A)P(B)]*P(C)
= P(A)P(C) + P(B)P(C) -...
Homework Statement
Given P(AUBUCUD), expand
The Attempt at a Solution
I approached the solution by procedurally drawing Vann Diagrams, building from AUB to AUBUCUD (Not included); Please do check if my line of reasoning is sound.
(let "n" be the intersection, AND)
1) P(AUB): P(A) +...
Excellent, I think this would be very helpful. Thank you very much.
@SteamKing: HNO3 could very well be the said acid but I gather that it isn't of much interest at the moment?
Homework Statement
Balance the following Chemistry equation, you are allowed to add H{+} and H2O where needed
Given
C6H5OCl + NO3- --> N2 + Cl- + CO2
2. The attempt at a solution
Balance the carbon first:
C6H5OCl + NO3- --> N2 + Cl- + 6CO2

I have stumbled upon the following equation on wikipedia

To clarify, I am not sure how to simplify the equation of the form
x^2/(1-x) = 1/(x^2 - x^-2)
as demonstrated in the second line of...
Hello ehild,
I feel awful for forgetting to thank you for all the contribution you've made towards this question, thank you. You've made me realize the alternative solution of not factoring out environmental effects on a system and I think that would be very valuable to me in the future.
As...
I've worked it out prior to this and I believe from (PV/T)i=(PV/T)f
Tf= c2Ti, when Pf= cPi and Vf= cVi
Does that imply that dT must increase in intervals of c2 in relation to dTi?

If I am understanding the statement correctly, the setup with a spring (of initial length when PV=0)...
The answers would be T= 12.18K and T= 109.62K respectively.
... However, I apologize for not seeing the relevance from here on out, as I am at a loss for another way such that ΔT directly dictates the ratio of P:V=1:1.
I am thinking that for any value of T for PV=nRT, P:V is not necessarily...
Hello ehild! Thanks for the welcome and reviewing the items above.
In addition to volume and pressure, temperature T is in proportion to PV as shown by PV=NkT. T could be proportional to either one or both of the factors depending on whether the other is a constant or no.
Assuming then the...
