AI Thread Summary

To solve the expression ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2, first square the second term, resulting in (6.84 x 10^-7) x (6.84 x 10^-7) = 4.67 x 10^-13. Next, multiply this result by the first term: (3.42 x 10^-7) x (4.67 x 10^-13). When multiplying, combine the coefficients (3.42 x 4.67) and add the exponents (-7 + -13), leading to a final answer of 1.6 x 10^-19. Understanding the multiplication of coefficients and the addition of exponents is crucial for these calculations. Mastering these steps will enhance proficiency in solving similar chemistry-related math problems.

In the expression:

ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2
= 1.6 x 10^-19

I don't understand how the final answer is found. Can someone show me a step by step? I'm attempting to understand how to do these types of questions! Any help is greatly appreciated!

You're having trouble multiplying the exponents? I have a feeling you didn't ask the entire question.

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
