for the experiment with eudiometer, you did not correct for the barometric pressure for the vapor pressure of water.
a 12.09-g sample of solid sodium bicarbonate completely decomposes into solid sodium hydroxide and carbon dioxide gas when heated.
After he cleaned up the mess, he looked around the baby's changing table for remedies for this horrible rash, but he could not find anything. As he was about to panic, he remembered some useful acid-base chemistry from a class years ago. He opened..
An aerosol can has a gas pressure of 133 kPa at 293 K. Calculate the pressure when the can is heated to 460 K.
Calculate the freezing point of a solution of 23.4 grams of benzoic acid (C6H5CO2H) dissolved in 613 grams
Chemical reactions are typically faster when a catalyst is added. This is because... 1. Molecules are moving faster when a catalyst is added
What pair of elements would you expect to exhibit the greatest similarity in physical and chemical properties? WHY?
At a certain temperature, Kp = 1.42 for the reaction PCl5 PCl3 + Cl2. Calculate the equilibrium partial pressures and the total pressure if the initial partial pressures are PpCl5= 2.88 atm , PpCl3 = 1.98 atm , and PCl2 = 1.42 atm.
At 22 °C an excess amount of a generic metal hydroxide M(OH)2, is mixed with pure water. The resulting equilibrium solution has a pH of 10.21. What is the Ksp of the salt at 22 °C?
change in enthalpy at 25 C and 1 atm for the reaction of 5.00 mol of elemental iron with excess oxygen gas?
An electric power station annually burns 3.6 107 kg of coal containing 1.8 percent sulfur by mass. Calculate the volume of SO2 emitted at STP.
Calculate the force of attraction between a cation with a valence of +2 and an anion with a valence of -2, the centers
When preparing 4-bromoaniline from 4-bromo-N-ethanoylbenzenamine, the hydrolysis mixture is rendered alkaline before the steam distillation. Why. It has something to do with acid/base reactions and volatilities of ionic compounds.
