Let's assume that to "make America great again" and support coal-powered electricity generation, the Trump Administration relaxes US emissions standards for SO2 and NOx from fossil fuel use, permitting a rise to a new emission target of 40 MT(S)/y and 40 MT(N)/y within the US. If 1⁄2 of all the emitted S and all of the emitted N oxidize to H2SO4 and HNO3, respectively, and fall as acid precipitation within the contiguous 48 states, what would the 48- state-average pH of precipitation be under these new emission levels?
A 100.0ml of sample of drinking water was buffered at PH 10.0 and after the addition of Calmagite indicator, required 35.41ml of 4.652X10^-3 m EDTA to reach the end point for the titration. Calculate the total hardness of the water in ppm of CaCO3
For 1 mol of an ideal gas, pext = p = 101 kPa (pressure remains constant). The temperature is changed from 100 degrees C to 25.0 degrees C. Calculate q, w, ΔU and ΔH. Assume CV,m = 3/2 R.
When 24 mL of a 175 mL stock solution containing 1.6 M BaF2 is diluted to 70 mL, what is the concentration of Ba2+ in the new solution?
When a space shuttle re-enters the atmosphere, its temperature rises and it can heat the surrounding air to 1260 degrees celcius. At that temerature some endothermic reactions take place that atlower temperatures are not spontaneous under standard..

The delta H for the neutralization of NaOH with H2SO4 is -144kj/mol H2SO4. What is the maximum measured temperature in the styrofoam cup
Applying energy to dry ice causes the molecules to phase change straight from a solid to a gas, sublimation. When gas particles hit the walls of a container, they exert pressure. As we apply energy to dry ice, the gas molecules move faster which..
