c) Write the reaction of nitrite with water, where transfer of a proton takes place. Identify the Bronsted-Lowry acid-base pairs.

Expert Solution

Nitrite (NO₂^-) reacts with water, H₂O as below.

NO₂^- (aq) + H₂O (l) -------> HNO₂ (aq) + OH^- (aq)

A Bronsted-Lowry acid is defined as a proton donor while a Bronsted-Lowry base is a proton acceptor. A Bronsted-Lowry acid loses one or more protons to form a conjugate base (also a Bronsted base) while a Bronsted-Lowry base accepts one or more protons to form a conjugate acid (also a Bronsted acid).

H₂O donates a proton to NO₂^- to form HNO₂. Therefore, H₂O is a Bronsted-Lowry acid and the conjugate base of H₂O is OH^-. Similarly, NO₂^- is a Bronsted-Lowry base since it accepts a proton. Thus, NO₂^-and HNO₂ form a Bronsted-Lowry base/acid pair.

The liquid-phase reaction A---> B + C takes place in a series of two CSTRs with an overall conversion of 0.75. Two newly purchased CSTRs are added to the series. The volumetric flow rate is then increased in order to keep the overall conversion at 0.75. (a) List all your assumptions. (b) If the original flow rate was 150 L/min, determine the new flow rate (L/min).

The following reaction takes place when some drain cleaners are added to water. What mass of hydrogen gas will be produced from 4.76 g of aluminum and 3.23 g of NaOH? 2Al(s) + 2 NaOH (s) + 6 H2O (l) ----> 2NaAl(OH)4 (aq) + 3 H2 (g)

Consider a CSTR where a simple first-order reaction takes place. The rate constant depends on the reactor temperature and can be given the Arrhenius equation. The reactor contents are cooled by a coolant that flows through a jacket around the reactor. Derive the dynamic model of the CSTR. i.e. the change of concentration of component A and the temperature of the reactor, assuming the flow rate and the inlet conditions are constant. You can use linearization technique for this coupled...

What is the increase/decrease in overall company profits if this transfer takes place?

Sunland Company manufactures and sells high-priced motorcycles. The Engine Division produces and sells engines to other motorcycle companies and internally to the Production Division. It has been decided that the Engine Division will sell 12000 units to the Production Division at 1050 a unit. The Engine Division, currently operating at capacity, has a unit sales price of $1750 and unit variable costs and fixed costs of $1050 and $700, respectively. The Production Division is currently paying $1600 per unit to...

Project 7: Acids and Bases A neutralization reaction depends on the transfer of a proton, hydrogen, from one substance to another. The substance that donates the proton is an acid. That which accepts the proton is a base. pH is a measure of the molar concentration of hydrogen ion in a solution. The strength of an acid is determined by its ionization potential, or the relative amount of the hydrogen ion present in a compound that can be donated. If...

1. Suppose the following reaction takes place: 2A+B+C----->products. The following observations are made: Halving the ]A] halves the rate of reaction, trippling the [B] has no effect f the rate of reaction, and tripling [C] increases the rate of reaction nine-fold. What is the overall order of the reaction? Please explain in clear details, thank you!
