Which compounds are Lewis acids? Select all that apply. □ N=C¯ AICI (CH,CH2)2HC+ NaHCO3

For each conjugate acid-base pair, identify the first species as an acid or a base and the second species as its conjugate acid or base. In addition, draw Lewis structures for each species, showing all valence electrons and any formal charge. (a) NH4+ NH3

Consider the following data on some weak acids and weak bases: acid base Ka name formula name formula HCH3CO2 1.8 × 10 C,H;NH, 4.3 × 10 5 10 acetic acid aniline hydrofluoric acid HF 6.8 x 10 ethylamine C2H;NH2| 6.4 x 10 Use this data to rank the following solutions in order of increasing pH. In other words, select a 'l' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. solution pH 0.1 М KF choose one 0.1 M C2H5NH3CI choose one 0.1 M NaCl choose one 0.1 M NaCH3CO2 choose one

Propylamine, C3 H7NH2, is a weak base. A 0.87 M aqueous solution of propylamine has a pH of 12.20. What is K, for propylamine? Calculate the pH of a 0.59 M aqueous solution of propylamine. K = pH Submit Answer Retry Entire Group 7 more group attempts remaining

Which is the stronger base, (CH3)3N or H2BO3− and why?

a Draw a structure for the product of the acid-base reaction below. :o: BF3 + • Include all valence lone pairs in your answer. • If the reaction is a Lewis acid-base reaction, draw the products in a single sketcher, with a single bond connecting the Lewis base and Lewis acid. • If the reaction is a Brønsted acid-base reaction, draw the products in separate sketchers. • Include all nonzero formal charges.

Which will be the stronger acid: propene (CH2=CHCH3) or propane (C3H8)? Explain by using resonance Lewis structures.

For conjugate acid-base pair, identify the first species as an acid or a base and the second species as its conjugate base or conjugate acid. In addition, draw Lewis structures for each species, showing all valence electrons and any formal charges. Q) CH3OH, CH3OH2+
