What volume and mass of steam at 100 degrees C and 1.00 atm would, during condensation, release the same amount of heat as 100.cm^3 of liquid water during freezing? What do you note, qualitatively, about the relative volumes and masses of steam and liquid water required to release the same amount of heat?
Suppose y was measured five times and average of these five measurements was 3.75. What is the uncertainty in x based on these five measurements?
Why is the Hydrogen atom of the -OH group on a carboxylic acid the most acidic hydrogen (the only H that can be removed by a base) in this type of molecule>
a sample of gas with a mass of 1.80 g occupies a volume of 921 ml at a pressure of 733 torr and a temperature of 24 c.
What is the strongest base that may exist in water. What happens to stronger bases
The procedure (paragraphs 2 and 3) states that the additions of bromobenzene, methyl benzoate and hydrochloric acid must be done slowly. What might happen if any of these were done too rapidly
What combination of a molecular base and a salt of the conjugate acid of the chosen molecular base should you select to prepare a buffer solution that would maintain a pH of 10.00?
At 700 K the equilibrium constant for the reaction is Kp = 0.76. CCl4(g)-> C(s) + 2 Cl2(g) A flask is charged with 2.00 atm of CCl4, which then reaches equilibrium at 700 K. (a) What fraction of the CCl4 is converted into C and Cl2?
After the reaction has reached equilibrium, the absorbance of the product C is measured and its concentration is determined to be 0.00745 M. Calculate the equilibrium constant for this reaction.
Consider the titration of 100.0 mL of 0.100 M H2NNH2 (Kb = 3.0 10-6) by 0.200 M HNO3. Calculate the pH of the resulting solution after 100.0 mL of HNO3 have been added
if 1.500 g of solute that has a molar mass of 125.0 g were dissolved in 35.00 g of camphor what would be the resulting
Gaseous NOCl is placed in a closed container at 193 oC, where it partially decomposes to NO and Cl2: 2 NOCl(g) 2 NO(g) + 1 Cl2(g) At equilibrium it is found that p(NOCl) = 0.008460 atm, p(NO) = 0.007950 atm, and p(Cl2) = 0.004590 atm. What is the ..
