Suppose that on another planet the atmosphere consists of 17% Kr, 38% CH4, and 45% O2. What is the average molar mass at the surface? What is the average molar mass at an altitude at which all the O2 is photodissociated?
Carbon sequestration technologies are being actively explored by researchers as methods to remove CO2 from the atmosphere, thereby diminishing the greenhouse effect.
The half life of potassium-40 is 1.26X10^9 yrs, if the natural abundance of k-40 is .010% and 3500 disinigrations of k-40 occur every 10 sec in a human body weighing 100kg then what is the concentration of potassium (include all isotopes) in that ..
what is the difference between using blue dye and red dye when determining the rate law for the oxidation by sodium hypochlorite?
Describe the reactant and products of the chemical reaction. Was the reactant (potato chip) completely consumed? What evidence supports your answer?
Two students reported a plus/minus 6.0% error. What was the highest alcohol density reported and what was the lowest alcohol density reported by the two students?
A 0.204-g sample of a CO3^2- antacid is dissolved with 25.0 mL of 0.0981 M HCl. The hydrochloric acid that is not neutralized by the antacid is titrated to a bromophenol blue endpoint with 5.83 mL of 0.104 M NaOH.
what is the balanced chemical reactions when carbon dioxide reacts with water? how can carbon dioxide change the ph of
The initial volume of the balloon is 5.00 , and the pressure is 760. The balloon ascends to an altitude of 20, where the pressure is 76.0 and the temperature is 50. What is the new volume, of the balloon in liters, assuming it doesn't break or leak
Lead(II) phosphate, Pb3(PO4)2 (s), is allowed to come to equilibrium with its ions in otherwise pure water. Ksp = 3.0 x 10^44. Calculate the equilibrium concentration of each ion.
A voltaic cell is constructed from an Ni2+(aq)--Ni(s) half-cell and an Ag+(aq)--Ag(s) half-cell. The initial concentration of Ni2+(aq) in the Ni2+--Ni half-cell is [Ni2+]= 1.20X10^-2M . The initial cell voltage is +1.12V.
should steam distillation be considered as a method of isolation and purification of an organic liquid that has a vapor pressure
In a separate experiment with the same initial conditions, a pressure of 2.50 atm was applied to the gas, decreasing its volume from 4.40 to 1.76L in one step. If the final temperature was the same for both processes, what is the difference betwee..
