Yes. Perfect. The only problem that happens in multiple choice questions is that students might forget to mention that the triple bond also contributes a sigma bond.
Let's use this equation and say that this is the starting point.
Now, you have doubled the incident photon's energy, which is one term on the right side. However, the second term, the work function, is still the same. This is the crux of the problem.
K.E. of photoelectron 1 = (KE of incident...
See, this is a VERY formulae based approach. We don't start with formula and apply it to situations, we draw/define situations, find what we need and THEN find out situations. I guess you started with v = u + at and then digressed into finding v/t.
THIS is why i suggested that you take a look...
Minimum implies there is a range on the values.
What is the condition when the minimum happens. What if you are crossing the road with less than the minimum speed?
Imagine physical scenarios :-D
So you have found the molecular masses of the oxide. Good.
Now use the fact that molecular mass of Oxygen atom is 16. What possibilities does it leave for the molecular mass of the other element?
Show some approximate calculations, and we'll proceed further!
Three unknowns, two equations.
Which means that you won't be able to solve this exactly. There won't be one unique solution to the percentages of the elements. It can stand for a variety of molecules, each with a different molar mass and HENCE the question asks you to go for the molecule...
I am assuming that the isotopic formula of the element asks you for that notation where you display both the atomic mass (protons + neutrons) and atomic number (protons).
Something like 1H1
Then, let's start from the beginning.
34 moles of electrons in X2 = 17 electrons in one atom...
Thank you! What an excellent reply!
I shall go over this and come back in some time. Thanks for the suggestions in Math Modelling.
As far as the not so obviousness of the posts go - well, I am not really inclined to be practicing bioprocess engineering (which IS akin to chemical engineering)...
So, its a long post and I feel I've been pushing this thing further and further without considering it properly.
Here's the background: I am doing a 5 year B. Tech. + M. Tech. Integrated course in Biotechnology and Bioprocess Engineering. There's one major issue though. My curriculum doesn't...
I am discussing this question with a friend.
Initial Thoughts:
* The force is applied to the bar, the plank will experience the same force till a certain point.
* This point is actually when F = at becomes equal to the maximum static friction between the two masses.
* So, initially, till the...
A plank of mass m1 with a bar of mass m2 placed on it lies on a smooth horizontal plane. A horizontal force growing with time t as F — at (a is constant) is applied to the bar. Find how the acceler-ations of the plank w1 and of the bar w2 depend on t, if the coefficient of friction between the...
