If the pressure exerted by a gas at 100°C in a volume of 8.04 L is 3.81 atm, how many moles of gas are present?

Explain in your own words and develop the reaction mechanism.

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

( 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).

Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If H,O, is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 7 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 미

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) >
