Le This may be helpful throughout the exam. For the Brønsted-Lowry acid base reactions shown below. list the stronger acid, stronger base, weaker acid and weaker base in the answer blanks provided: NH4+ H2PO4 NH3 + H2PO4 Stronger acid: Stronger base: Weaker acid: Weaker base:
In a Bronsted acid-base reaction, the stronger acid reacts with the stronger base to produce a weaker acid and a weaker base. Thus, whether a reaction “goes” or “does not go” can be used to determine the relative strength of the Bronsted acids and bases in the reaction. From the data below, determine the order of the strengths of the three Bronsted acids. Reaction 1: CH3CO2H + H2AsO3- → H3AsO3 + CH3CO2- goes Reaction 2: H2AsO4- + H2AsO3- → H3AsO3...

A form of the nicotinamide ring of NAD^+ is shown below. Modify the molecule on the right to show NADH. Show all hydrogen atoms and nonbonding electrons.
In the presence of water one of the products is shown below: R-Mg-Br + H-OH → RH + HO + Mg2+ + Br Grignard Water Alkane Hydroxide ion Reagent Stronger acid (weaker acid) (weaker base) (stronger pka= 15.7 pka 40-50 base) Q1. If R= Phenyl, what is one of the major products with moist ether? Q2. If R= t-butyl, what is one of the major products with moist ether? At a higher concentration of bromobenzene one of the products is...
Do you expect taurine to be a stronger or weaker acid than H2SO4 and/or H2SO3? please include a drawing of the structure
4. Two phosphoric acid molecules can combine to make pyrophosphoric acid and another molecule, as shown here The pyrophosphoric acid molecule is a phosphoster and is a structural element in the ADP/ATP metabolic energy system. What molecule is represented by the question mark in the structural reaction equation below? LIL HOP -OH + HO—B—-OH — HO - - O- P- OH + ? OH OH OH
Consider the figure shown below. What is the pK_a of hydrogen cyanide, HCN? what is the value of TOTCN for the solution depicted in the figure? Is hypoiodous acid, H0I (pK_a = 10.70), a stronger or weaker acid than HCN? Type stronger or weaker, then briefly explain. Which is the stronger base, cyanide (CN^-) or hypoiodite (OI^-)? Type cyanide or hypoiodite, then briefly explain.
