Whether Na + or F − is larger has to be determined. Also, the representation of the shape of the highest energy occupied orbital has to be drawn. Concept Introduction: Atomic size is half of the distance between the adjacent atoms in the molecule. Since the electron cloud has no fixed boundary so the size of the atom is measured with high difficulty.

Question

Using the conditions of spontaneity to deduce the signs of AH and AS Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions A This reaction is always spontaneous, but proceeds slower at temperatures above 120. °C. ΔΗ is (pick one) AS is (pick one) ΔΗ is (pick one) B This reaction is spontaneous except above 117. °C. AS is (pick one) ΔΗ is (pick one) This reaction is slower below 20. °C than C above.

Answer 1

Question

Chapter 8, Problem 8.54QE

Interpretation Introduction

Interpretation:

Whether Na+ or F− is larger has to be determined. Also, the representation of the shape of the highest energy occupied orbital has to be drawn.

Concept Introduction:

Atomic size is half of the distance between the adjacent atoms in the molecule. Since the electron cloud has no fixed boundary so the size of the atom is measured with high difficulty.

Calculating the pH at equivalence of a titration Try Again Your answer is incorrect. 0/5 a A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of hydrocyanic acid is 9.21. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. pH = 11.43] G 00. 18 Ar B•
