Calculating the reaction rate of one reactant from that of another Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. alo Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 514. liters per second of dioxygen are consumed when the reaction is run at 213. °c and the dioxygen is supplied at 0.64 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits. Ar kg x10 S ||

A 10-mm cube of copper metal is placed in 250 mL of 12 M nitric acid at 25°C and the reaction below occurs: Cu(s) + 4H+(aq) + 2NO3(aq) → Cu2+(aq) +2NO2(g) + 2H20(I) At a particular instant in time, nitrogen dioxide is being produced at the rate of 2.3 × 10^-4 M/min. AT this same instant, what is the rate at which hydrogen ions are being consumed in M/min? Report you answer with 5 places past the decimal
Can someone please help? The question is:
( the reaction 2 HgO(s)--> 2 Hg(1) + O2(g) we measure the evolution of gas to determine the rate of reaction. At the beginning of the reaction (at 0 minutes), 0.020 L of O2 is present. After 15 minutes the volume of O2 is 0.35 L. What is the rate of reaction in L/min? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

PLEASE,ASAP!!!!! Each step of a four-step reaction has a percent yield of 95%. What is the percent yield of the overall reaction?
In the laboratory, hydrogen gas of good purity can most easily be obtained by the reaction of a strong acid, like sulfuric acid, on a reactive metal, such as zinc: Zn(s)+H,SO,(aq) ZnSO,(aq)+H, (g) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 160.9 g of solid zinc and 83. mL of 5.0 M sulfuric acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. alo Ar initial rate of vessel volume temperature reaction A 1.0 L 14.0 °C В 4.0 L 14.0 °C ? 2.0 L 14.0 °C 8.0 L 14.0 °C v ? 1 (highest) 2 4 (lowest) >
