Solving this question in a certain way

AI Thread Summary
The discussion outlines a systematic approach to solving chemical equilibrium problems using the reaction H2 + I2 = 2HI as an example. It details the initial amounts of reactants and the equilibrium constant, leading to the calculation of the concentration of HI at equilibrium. The method involves setting up an ICE table (Initial, Change, Equilibrium) to track the changes in concentrations. A second example is presented, involving the reaction 2A = B + 3C, where the equilibrium concentrations are used to find the equilibrium constant K. The thread emphasizes the importance of this structured approach for solving similar questions effectively.

this is the general way i solve every question:
example of a solved question in this way

we put 0.8 mole of H2 1.3 mole of I2 in one litter cantainer

the balance constant is 10.7
calculate how much 2HI will be in the container when the reaction balances

H2 +I2 = 2HI
start 0.8 1.3 0
moves -x -x +2x
end 0.8-x 1.3-x 2x

there are two solutions but only one is possiblr
x=0.0604
[HI]=0.12how to solve this question in the same way
we mix 0.5 moles of A
1 mole of B
2 moles of C
in a one litter container

after it balances we find 0.6 moles of A
find K for
=(is a sign where two arrows go in different directions)
2A =B+3c

Very nice! Glad to be of assistance.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
