Question

10 mmol of strong base acid 20 mmol of strong base two an F test, you find that FFe This result indicates the two A) standard deviations; not significantly different B) standard deviations; significantly different C) data sets; not significantly different D) data sets; significantly different 3. As the activity coefficient approaches 1, which of the following statements will be A) activitys activity coefficient B) activity coefficients concentration C) activity concentration D) all of the above 4. Which one of the following conditions is met at the equivalence point of the titration of a monoprotic weak acid with a strong base? A) The volume of base added from the buret must equal the volume of acid titrated B) The moles of base added from the buret equals the initial moles of acid. C) The molarity of the base equals the initial molarity of the weak acid. D) The pH of the solution is equal to or less than 7.00. As its state has electrons whose spins are 5. A molecule in the electrons relax back to the singlet ground state, the molecule will A) singlet, opposed, fluoresce B) singlet, parallel, phosphoresce C) triplet, parallel, fluoresce D) triplet, opposed, phosphoresce Page 2 of 14 CHEM 210, Spring 2016-Final Exam DOF =

Explanation / Answer

Q5 is visible and Clear and I am going to answer this question for you.

Singlet has electrons with opposite spins and triplet gas electrons with same spin.

When molecule decay from excited singlet state to the ground singlet state, it is called fluorescence.

So, for the Q5, the correct answer is option "A", which you can deduce from the explanation given above.

Even you can rule out the different option from the explanation given above. Check the different options and compare with the explanation given above, you will find that option A is only correct.

Thank You
