Review I Constants I Periodic Table The U.S. Environmental Protection Agency (U.S. EPA) monitors air quality in the United States. Lead is among the pollutants regularly monitored and regulated. Lead is released into the atmosphere primarily by the processing of metals ores containing lead and by lead-based battery manufacturing. The effects of too much exposure to lead include neurological damage and cardiovascular disease. Because of the Clean Air Act and its amendments, the amounts of lead in air have been decreasing for many years. The chart below shows the lead concentration in air in the United States from 2000 to 2014 (Figure 1) Previous Answers Submit Correct A decrease in -83% is a substantial improvement in air quality from 2000 to 2014 Part D How many lead atoms were in one cubic centimeter of air in 2006? Express the number of lead atoms numerically. View Available Hint(s) Figure 1 of 1 Lead Concentration in Air in U.S Vη ΑΣφ ? 3.5 108 0.35 Pb atoms 0.3 0.25 Previous…

I need help with these two questions

Use the information below to answer questions 1- 3. PCI,(g) 2 PCI;(g) + Cl2(8) PCI,(g) decomposes into PCI,(g) and Cl,(8) according to the equation above. A pure sample of PCI,(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCI5(g) is 1.00 atm. The temperature is held constant until the PCI,(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. PCI5 Potal = 1.00 atm PCI5, PCI3, and CI, Prstal = 1.40 atm Figure 1: Initial Figure 2: Equilibrium As the reaction progresses toward equilibrium, the rate of the forward reaction (A) increases until it becomes the same as the reverse reaction rate at equilibrium (B) stays constant before and after equilibrium is reached (C) decreases to become a constant nonzero rate at equilibrium (D) decreases to become zero at equilibrium If the decomposition reaction were to go to completion, the total pressure in the container would be (A) 1.4…
