Heating HI(g) at 425 degree C causes some of this compound to decompose, forming H2(g) and I2(g). Eventually, the amounts of the three species do not change further; the system has reached equilibrium. (at this point, approximately 22% of the HI has decomposed.) Describe what is happening in this system at the molecular level.
Assuming 100% dissociation, calculate the freezing point and boiling point of 2.72 m AgNO3(aq).
how much energy is needed to heat 24.8g water from 64 degrees to 123 degrees celsius?
Briefly discuss the importance of the principles of solubility and miscibility when choosing extraction solvents
25.2 mL of qater are placed in a graduated cylinder. A 22.6 g stone is dropped in, and the water level rises to 32.4 mL. Find the stone's density.
Draw the reaction energy diagram for this reaction mechanism. In your diagram, label for each step, Estimate the relative amount of each product that would result. Please show all of your math
Calculate DeltaG °rxn. c) In which direction is the reaction, as written, spontaneous at 25 °C and standard pressure?
On the obtained mass-spectra you got in the expected parent-ion mass region two adjacent lines with almost the same abundance (m/z=258 -100%, and m/z=260 -97%). Fragments do not show any adjacent abundant lines. What conclusion can you derive from..
Regarding the Human Genome Project (HGP) ~ Do you expect this sort of work to yield additional medical therapies as time goes on
A reaction mixture initally contains 0.56 atm CO2 and 0.32 atm CO. Determine the equilbrium pressure of CO if Kp for the reactions at this temperature is 2.25?
A student in lab has 2.00 g of pure N2 in 0.360 g pure H2. The reaction happens following this equation:
A rubber balloon was inflated with helium gas and floated in the air. The next day, the balloon was somewhat smaller and no longer floated.
In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) HO(g) Use the data below to calculate the value of Kc
