A 4 liter sealed container contains water vapour at 4 atm and 90 C.
1- what is the vapour dew point?
2- what is the percentage of the vapour that will condense if the system called to 50 C?
Identify the compounds present in the mixture and determine the percent by mass of each in the original sample. 1 Identity and % (wt/wt)= 2 Identity and % (wt/wt)=
Using curved arrows to show the flow of electrons and being careful to balance mass and charge for each step, provide a mechanism for the reaction below that show how both products are formed
Consider a particle in a one-dimensional box, the longest transition wavelength for the particle is 200 nm. What is the transition wavelength if the mass of the particle is doubled
What is the internal energy of an ensemble of 1 mole of particles having two non-degenerate electronic energy levels separated by 1000cm^-1 at 1310K.
You have a 1.0 mL sample of unknown concentration that requires 8.0 mL of titrant to change the color of the solution. How many mg of ascorbic acid are in your unknown sample
It is then analyzed on the ICP. The ICP results show the liquid to be 64.8 PPM Na and 43.7 PPM P. What does this reveal about the original dry powder
what is the molarity of a solution made when you dilute 35 grams of sodium carbonate to a volume of 3400 ml?
Perform each of the following conversions,being sure to set up clearly the appropriate conversion factor in each case- i) 2.4 lb to kilograms
What mass of real van der waal behaving form of N2 gas is present in a 50l container at 400K under 20 atm of N2 pressure where a=1.37 litre^2 bar mole^-2 and b=0.0387 litre/mole
1. identify the element of lowest atomic number whose electron configuration contains four completely filled
state whether the equilibrium mixture contains mostly products or reaction and why. HNO2(aq) + HS(aq) ---->(double arrow) H2S(g) + NOs(aq) and Cl(aq)+ H2O(l) ---->(double arrow) OH(aq) + HCl(aq)
