Explain, in chemical terms, why metal sulfide compounds can only form after the hydrothermal fluids escape into the open seawater.
A 2 mL solution containing 1.40 uCi/mL is injected into the blood stream of a patient. After dilution, a 1 mL sample is withdrawn and found to have an activity of 2.9 * 10-4uCi. Calculate the blood volume,
heat of solution of lithium carbonate is -3.06 kJ/mol solute in 200 moles H2O. What effect would you expect increased temperature to have on the concentration of Li2CO3? Explain
solid NaI is slowly added to a solution that is 0.010 M in Cu+ and 0.010 M in Ag+. which compound will begin to precipitate first?
A sample containing 3.00 mol of an ideal gas at 25C is expanded isothermally and reversibly from an initial volume if 6.0L to a final volume of 24.0L. Calculate deltaG and deltaA for this process.
The density of the hydrogen peroxide solution is 1.01 g/mL and the solution contains 3.40% H202 by mass. The vapor pressure of water at 24C is 22 mmHg. Based on this data and information calculate the molar volume at STP.
What is the difference between electron geometry and molecular geometry? How can knowing both assist in determining whether a molecule is polar or nonpolar?
Write the rate law for the clock reaction (equation 1) using variable for exponents.
A 0.0100 molal aqueous solution of a weak acid freezes at -0.0219 oC. Calculate the percent ionization of the weak acid, HA.
An evacuated (empty) 276 mL glass bulb weighs 129.6375 g. Filled with an unknown gas, the bulb weighs 130.0318 g. Calculate the gas density in g/L.
