3. the rate law for the reaction nh4+(aq) + no2–(aq) → n2(g) + 2h2o(l) is given by rate = k[nh4+][no2–]. at 25ºc, the rate constant is 3.0 × 10–4/ m · s. calculate the rate of the reaction at this temperature if [nh4+] = 0.26 m and [no2–] = 0.080 m. (5 points)

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.

Energy defines the different "states" of matter. in no more than 3 sentences, describe the amount of kinetic energy that each of the 3 states of matter possesses and relate that to the atom/molecular motion of each "state".

Why is it possible for different microorganisms to extract energy not only from carbohydrates and other biological molecules but from a large variety of substances?
