A lab bench has three one liter stoppered flasks. Flask A contains one gram of NH3 gas, flask B contains one gram of N2 gas, and flask C contains one gram of SO2 gas. All are at the same temperature. 1) Which flask has the greatest pressure? a,b,c, they're all the same or none 2) Which flask has the fewest molecules? a,b,c, they're all the same or non 3) Which flask has the molecules with the greatest average speed (velocity)? a,b,c, they're all the same or non 4) Which flask has molecules with the greatest average kinetic energy? a,b,c, they're all the same, or none 5) Which flask has gas with the greatest density? a,b,c, they're all the same or none
Consider the ionic strength of the solution to be 0.10 M and consider each ionic form of aniline to have an activity coefficient of 0.77.
RNA-based viruses such as poliovirus use RNA as their genetic storage material. An important anti-viral drug is ribavirin (see below). RNA polymerase can use ribavirin (the triphosphate version) as a substrate,
If the first order half life is 300. seconds at 35 degrees Celsius and the initial concentration of hydrogen peroxide in a commercial Winn-Dixie product is 0.050M, then after 30 minutes, calculate the concentration of the hydrogen peroxide expecte..
If a 220mg piece of gold (density =19.32 ) is hammered into a sheet measuring 2.11.0 , what is the average thickness of the sheet in meters.
Compare volumetric glassware (volumetric flasks, pipets, burets) with other routine glassware (Erlenmeyer flasks, graduate cylinders, beakers) by sorting the qualities or properties into the correct bins.
A mixture of 82.49 g of aluminum (MM = 26.98 g/mol) and 117.65 g of oxygen (MM = 32.00 g/mol) is allowed to react. Identify the limiting reactant and determine the mass of the excess reactant present in the vessel when the reaction is complete.
If 205 grams of water at 31C absorbs 281kJ of heat from a mountain climber's stove at an elevation where the boiling point of water is 89C, is this amount of energy sufficient to heat
If a divalent metal ion is inserted in the center of the porphine ring, its charge will exactly balance the two negative charges of the dianion. Write a balanced equation for the reaction of tetraphenylporphyrin (which you can abbreviate as TPP) w..
