Problem- A backpacker collects snow at 0 C, and places it in a cooking pot on a camp stove. It takes 643 kj of heat energy to melt the snow and bring the water to boiling. Assuming no heat loss, and neglecting the specific heat capacity of the pot, calculate the mass of snow that the backpacker collected.
(Data: specific heat capacityof liquid water, c = 4.18 J/ g.K; and: H20(s) -> H20(l), /\H= Hfusion = 6.02 kJ/mol
A) 1.92 kg B) 1.90 kg C) 1.52 kg D) 855g E) <800g
Illustrate structures to prove your interpretation.
if you burn 10.00g of octane. if the temperature is 500K, and you have an expansion of 1.00 atm, how much work in joule can be done by the system if the octane is completely converted to CO2 and water vapor. what will be the enthalpy change
what is the depth below the surface at which the concentration is 1016 atoms/cm3 if the surface concentration is maintained at 1018 atoms/cm3? Use D = 2 x 10-12 cm2/s for aluminum diffusing in silicon at 1100?C.
In the reaction 2 C8H18 + 25 O2 ? 16 CO2 + 18 H2O, if the rate of change in the concentration of CO2, ?[CO2]/?t, equals 0.51M/s, what is the value of ?[O2]/?t, the rate of change in the concentration of O2

At 25°C, you take 100 mg of Na2CO3 as well as 100 mg of CaCl2; place them into a 1 L volumetric flask as well as add water at a pH=9.0. Will CaCO3 precipitate. Presume closed system with a constant pH
Please provide a multistep synthesis for the following product (hexane) from the provided starting material (butanol) and any reagents or compounds with 2 carbons or less (Hint: you should be able to do this in 3 steps).
Capital V will stand for Vbarr(molar volume) (P+(a/V^2))(V-b)=RT is the van der Waals equation and when it is solved for V you obtain cubic equation V^3-(b+(RT/P))V^2+(a/P)V-ab/P=0
