How many joules of energy are needed to melt 27.0 of acetic acid? Heat of fusion (acetic acid)= 192J/g.
Draw the Lewis structure of formic acid, HCO2H. (Hint: C is the central atom. One of the H is bonded to an O.) How do we know which of the possible structures for HCO2H is more likely to be correct?
At 5 oC the equilibrium constant for the reaction: 2 HBr(g) H2(g) + Br2(g) is KP = 2.80e-16. If the initial pressure of HBr is 0.00991 atm, what are the equilibrium partial pressures of HBr, H2, and Br2? p(HBr) = . p(H2) = . p(Br2) =
The reaction is between furan and maleic anhydride. Using 0.19 g of furan and 0.24 g of maleic anhydride.
Write the expression for the equilibrium constant, Kc, for the following chemical reaction.
If the pressure increases to 800. torr, how many moles of gas were added to the container? Assume a constant-volume container.
consider the reaction in which 410g of Ca(NO3)2 react with just the right amount of magnesium metal in a single replacement reaction. how many grams of lithium are required?
How much of 2,4 hexadien-1-ol would you need to react with 98 mg of maleic anhydride in a Diels-Alder Reaction? (Assume a 1:1 molar ratio of maleic anhydride to 2,4 hexadien-1-ol)
A sample of chlorine gas in confinedin a 5.9L container at 220. torr and 27 degrees Celsius. How many moles of gas are present in the sample?
what is the pH of the resulting solution after the nuetralization reaction (that is after the required amount of NaOH is added to the lactic acid)? Use a Ka of .00014 for lactic acid and assume that the solid was dissolved in 15.0 mL of distilled ..
A 12 m 11 m 3.0 m basement had a high radon content. On the day the basement was sealed off from its surroundings so that no exchange of air could take place.
A bicycle tire is filled with air to a pressure of 611 kPa at a temperature of 19 degrees C. Riding the bike on a hot day increases the temperature of the tire to 58 degrees C.
