Drinking mineral water but I do not like too many dissolved ions in the water. Therefore, I bought a water carbonation machine. This machine works by providing CO2 at 5 atm. Estimate the concentration of the soda water it produces. Use a Henry's law constant of 1.25 x 106 K/Torr and assume the water is at 25 0C.
The student found that 8.67mL of NaOH solution was needed to titrate a 0.0544g sample of the acid to the equivalence point. Calculate the mass of unknown required for a 30.0mL titration.
What will be the volume of HCl 0.2750M, measured by burette, needed to consume all of the Calcium Carbonate that is contained in a block of that material that has dimensions of 2.5 x 1.0 x 0.5 inches
Problem- What is the pH of an aqueous solution prepared to initially contain 0.100 M NaHSO4 and 0.100 M BaCl2? Ka=1.2x10^-2 for HSO4- and Ksp = 1.1x10^-10 for BaSO4
Draw the energy profile diagram to show the possible intermediate and the transition states.
when 3.299 of iodine reacts with fluorine, 5.768g of IFx is formed. What is the value of x in product formula (IFx)?"
a calorimeter consists of metal parts with a heat capacity of 850.0 j k-1 and 1100 g of oil with a specific heat of
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 18.9 L of oxygen gas at 25.0oC and 1.25 atm, and 7.58 L of helium gas at 25.0oC and 1.13 atm were pumped into a tank with a volume of ..
How is hydrogen bond differnt from an ionic or covalent bond?
Given: Volume of He sample = 72.5mL Temperature = 30 C Atmospheric pressure = 785 mmHg Equilibrium vapor pressure of water at 30 C = 31.88 mmHg What is the ratio of average molecular velocity between He(g) and H2O(g)
Gold, like iron and copper, can have more than one monatomic cation. Knowing this, a mining company wanted to find the formula of a gold - chlorine compound that it has come across during its mining operation.
The experimental conditions are a modified perkins reaction (benzaldehyde + sodium acetate + acetic anhydride).
Calculate the delta G for each of the following reactions. State whether each reaction is spontaneous or non-spontaneous at standard conditions, and explain your reasoning.
