I know that for increasing melting points is C, A, B. So could you please explain how you can estimate the order of increasing melting points for the following compounds. Why is the estimate rather inaccurate
Estimate the vapor pressure of sea water at 20 degrees celsius given that the vapor pressure of pure water is 2.338 kPa at that temperature
A half-life of phosphorus-32 =14.0 days. starting with six grams of 32P, determine how many grams would remain after 112 days
What is the SUM of all of the coefficients in the reaction. 2 C8H18 + 25 O2= 16 CO2 + 18 H2O
A urine sample was found to have a pH of 5.83. What would be the ratio of the unprotonated form, A, to the protonated form, HA, for uric acid in this urine sample?
A pH of 3.74 is reached when 18.50 mL of sodium hydroxide has been added to the acid solution. What is the molar mass of formic acid given this data?
Exactly 5.02 grams of an unknown gas was sealed in a 3.0 L flask at 37.0oC and a pressure of 1.25 atm.
In relation to the previous question, diazonium salts couple with phenols in slightly alkaline solution. What effect does the pH of the solution have on the reactivity of the phenol?
Consider the substitution reaction of H2S-BH3 with NH3, which generates two product molecules (ignore the states of matter), assuming that no species exceeds the octet rule. Given the following information:
prepared by dissolving 33.2 g of the compound in sufficient water to form 250 mL of solution. The solution has an osmotic pressure of 1.2 atm at 25 °C. What is the molar mass (g/mole) of the compound?
would be decomposed by a complete reaction with one drop of water? Assume that 1 drop ~ 0.05 mL. If you started with 0.4 g of trityl fluoborate, how much of it would have been left?
In spectroscopy, the ratio of the intensity of radiation that passes through (I) the sample and the intensity of the radiation (Io) that is directed at the sample being analysed is called
If 18.4 mL of 0.800 M HCl solution are needed to neutralize 5.00 rm mL of a household ammonia solution, what is the molar concentration of the ammonia?
