A septic tank leaks into the soil. The organic matter decomposes to produce carbon dioxide. Gas flow is restricted in the soil so that there is no air exchange to the atmosphere above. The carbon dioxide develops a pressure of 350 Pa. Calculate the pH of the soil water assuming no buffering ability.
Identify the potential donor atoms in each of the following Lewis bases and classify the donor atom(s) as hard soft or borderline bases
Consider the temperature change, together with the volume and concentration of the acid and base, noted in the HAZMAT team's response regulation information
newman projection along c3-c4 bond to show thw most stable and least stable confirmations of 3-ethyl-2,4,4,-trimethylheptane?
Consider an area-source box model for air pollution above a peninsula of land. the length of the box is 15 km, its width is 80 km, and a radiation inversion restricts mixing to 15 m.
If 25.00 mL of 0.687 M Fe(NO3)2 are added to a flask containing 0.289 g of aluminum metal, what compounds will be present in the flask once the reaction is complete? (Ignore water, etc.)
When ammonium chloride, NH4Cl, dissolves in water, the temperature of the solution is found to be less than that of the original water sample.
If you wanted to prepare a solution of CO in water at 25 degrees Celsius in which the CO concentration was 2.5 mM, what pressure of CO would you need to use?
Calculate the atomic mass of neon (Ne) which is composed of three naturally occurring isotopes with the following natural abundances and masses
At a certain temperature and pressure 2.1 L of H2 reacts with 2.1 L of I2. If all the H2 and I2 are consumed, what volume of HI, at the same temperature and pressure, will be produced?
In this experiment a hot metal block at 100oC is added to cold water in a calorimeter. The heat lost by the metal block equals the heat gained by the water and the two end up at the same temperature.
Determine the molar concentration of chloride ions after adding 225 ml of 0.625 MKCL with 615 ml of 0.385M MgCl2 if final volume of the solution is 840ml.
Write the chemical equation(s), including state symbols, for what happens when each soluble ionic compound that you identified above is placed in water. Are these substances reacting with water when they are added to water?
