HClO is a weak acid (Ka=4.0x10-8) as well as so the salt NaClO acts as a weak base. Explain what is the pH of a solution that is 0.028 M in NaClO?
Predict that it was dissolved in HCl then mixed into the diethyl ether because diethyl ether is a base and since the benzoate contains an amine group they would remain unreactive with one another.
It takes the films 7.4 seconds to traverse the 1.2 m between two calibration marks on the tube. What is the rate of generation of CO2 in the moles per minute
An 80.0-gram sample of a gas was heated from 25 °C to 225 °C. During this process, 346 J of work was done by the system and its internal energy increased by 6275 J. What is the specific heat of the gas
100.0g of Cl2O7 are mixed with excess of water obtaining 136.0g of periodic acid according to the following reaction. Determine the percent yield of HClO4.
The second order reaction for the breakdown of nitric oxide to its elements has the rate constants of 0.0796 L/mol-s at 737 C and 0.0815 L/mol-s at 947 C. What is the activation energy of this reaction?
pH will be greater than 7 at the equivalence point. C. titration will require more moles of base than acid to reach the equivalence point. D. pH will be equal to 7 at the equivalence point. E. titration will require more moles of acid than base to..
A solution of 53.6 g of glycerin in 133.7g of ethanol has a vapor pressure of 113 torr at 313K. Calculate the vapor pressure of pure ethanol assuming that glycerin is a non-volatile, non electrolyte solute in ethanol.
