A scuba diver at 80 m below the surface of a lake, where the temperature is 6 degrees C, releases an air bubble with a volume of 14 cm^3. The bubble rises to the surface, where the temperature is 22 degrees C. What is the volume of the bubble (in cubic centimeters) just before it reaches the surface? (The density of water is 1000 kg/m^3 and air pressure is 1E+05 N/m^2.)
Calculate the equilibrium constant, Ke, for the reaction assuming the concentrations for reactants and products are the following
What is the total volume of gases produced at 819K and 1atm pressure when 256 g of ammonium nitrate (NH4NO2) undergoes the following decomposition?
If 36.0 mL of 0.150 M HCl(aq) is needed to neutralize all the NH3(g) from a 2.25-g sample of organic material, calculate the mass percentage of nitrogen in the sample.
The sulfide content in a pulp plant effluent is determined with a sulfide ion-slective electrode using the method of standard additions for calibration.
what effect does conjugation (alternating single and double or alternating single and triple bonds) have on the location
Calculate the number of moles of hydrogen gas that can be produced by the reaction of excess water with 8.75 x 1021 atoms of barium.
Find the value of Pressure - How much more pressure will the gas exert if the temperature is raised to 44.1°C?
Elements in the first short period are limited by the octect rule whereas those in the higher period can expand their valence shells. Describe what this means, account for this phenomenon and give an example of each.
If the specific heat of the ball bearing is .474 J/g times degress C, calculate the final temperature of the water. Assume the calorimeter to have neglible heat capacity.
Why is the installation of an automatic sprinkling system recommended in machine shops that use lathes to fabricate titanium parts?
Sulfur dioxide gas is oxidized in 50 percent excess air with 70 percent conversion to sulfur trioxide. The gases enter the reactor at 350 oC and leave at 450 oC.
The mass ratio of sodium to fluorine in sodium fluoride is 1.21:1. A sample of sodium fluoride produced 36.5 {rm g} of sodium upon decomposition. How much fluorine (in grams) was formed?
