An aqueous solution of 500 mg/L Hg(NO3)2 has leaked from a ruptured 208 L (55 gal) drum. Visual inspection of the area around the drums suggests that the compound is confined to an area approximately 4 m in diameter and 0.2 m deep. Estimate the concentration (mg/kg) of mercury in the soil. Assume soil bulk density = 1,800 kg/m³. %3D

The density of potassium, which has the BCC structure, is 0.855 g/m3 .The atomic weight of potassium is 39.09 g/mol. Calculate (a) the lattice parameter; and (b) the atomic radius of potassium.

01) sample of crude oil (density = 55 ib\f3). It contains dissolved gas (Gas Solubility = 200 m3\m3, the apparent molecular weight = 25.4) at temperature 120 F and pressure 2000 psi. Name the viscosity at that pressure (and why) and calculate it.

To make a 413.1 ppm solution, what volume (L) of solvent (1.23 g/mL) would be needed for a solution that contains 3.17 grams of solute (86.32 g/mol)? Report your answer to the hundredhs place and do not include units.

A Carnot cycle is a cycle of special interest because: When it is carefully constructed in a laboratory, it provides an upper limit on cycle efficiency. It provides the maximum efficiency for any cycle It operates between two constant-temperature thermal reservoirs It establishes a lower limit on cycle efficiency.

ons Problem 8 Find out the real gas formation volume factor in bbl/scf when there is no presence of inorganic impurities. The specific gravity of gas is 0.6; the temperature is 104 °F; and the pressure is 2,794 psi. Problem 9 Calculate the gas viscosity of the gas with the gas properties from Question 8. (Hint: Look at the bullet list immediately after Equation 3.76 for calculating the gas density in gm/cc).

The “Quick Fill” bicycle tire filling system consists of a small (2 cm diameter, 6.5 cm long) cylinder filled with nitrogen to a pressure of 140 bar. Estimate the explosion equivalent of the gas contained in the cylinder in grams of TNT

Q.1) In the experiment, you wrap a piece of copper wire around your magnesium strip to suspend the magnesium inside the eudiometer. Why is copper wire a good choice for this task? Group of answer choices It conducts electricity very well It reacts strongly with the acid It does not react with the acid It is much heavier than Mg   Part B) A 45 mL sample of a dry gas is collected at 380 torr and 25 °C. Calculate the volume of the gas sample (in mL) at STP.   Part C)Using the data provided in Table 3 in the handout (also provided below), calculate the vapor pressure of water at 21.0 °C.
