Enter your answer in the provided box. Mercury (Hg) is present in trace amounts in coal, ranging from 50 to 200 ppb. A typical power plant burns 2.0 million tons of coal per year. Calculate tons of mercury in the coal based on the lower (50 ppb) and higher (200 ppb) concentrations. Mercury at 50 ppb = tons Hg Mercury ay 200 ppb = tons Hg

Enter your answer in the provided box. Remember to enter your answer to the correct number of significant figures. For the reaction: A(g) + B(g) → AB(g) the rate is 0.24 mol/L·s, when [A]0 = [B]0 = 1.0 mol/L. If the reaction is first order in B and second order in A, what is the rate when [A]0 = 2.6 mol/L and [B]0 = 2.7 mol/L?
Enter your answer in the provided box. Remember to enter your answer to the correct number of significant figures. For the following reaction, the rate is 0.27 mol/(L·s) when [A]0 = [B]0 = 1.0 mol/L: A(g) + B(g)→ AB(g) If the reaction is first order in B and second order in A, what is the rate when [A]0 = 2.0 mol/L and [B]0 = 3.3 mol/L?
