To keep it really simple, Ar has 18 electrons. Then adding the 2 electrons of the 4s orbital , we get 20 which is the atomic number of Calcium whose symbol is Ca.  Similarly, Kr has 36 electrons. Then adding the 2 electrons of 5s, 10 electrons of 4d and 4 electrons of 5p orbitals,...

Was not sure if you meant -1/(2x)+ 1/(6y) = 2/3 or (-1/2)x + (1/6)y = 2/3 The solution for -1/(2x)+ 1/(6y) = 2/3 is as follows: -1/(2x) + 1/(6y) = 2/3 could be rewritten as follows by adding 1/(2x) to both sides of the equation. -1/(2x) + 1/(2x) + 1/(6y) =...

Although for this question, you will have to determine the Van't Hoff factor using the formula, there is a neat of verifying your answer.  Let us denote the Van't Hoff factor by i. The i value for a molecule like say glucose (does not dissociate when dissolved in a solvent like water)is...

4x - 2z = b-2.  In order to solve for x, shift all the other terms to the R.H.S (Right Hand Side of the equation). 4x = b-2 +2z Now divide both sides by 4.  x = b/4  -2/4 + 2z/4  (Now we have to simplify or reduce the fractions)    =  b/4...

She was struggling with the course but had to complete the course with a decent grade for a degree in Graphics Design. She was completely clueless about the basic concepts and could not solve any of the Physics problems assigned as homework... read more
