How many moles of CF4 can be produced when 5.00 mol C react with 12.00 mol F2.
What is the pH of the solution after 50.0 mL of base has been added? What is the pH of the solution at the equivalence point
Calculate the molarity of Ag in a solution resulting from the mixing of 30 mL of a 0.0250 M AgNO3 solution and 11.51 mL of K2CrO4
How many moles of NaOH would be required to completely neutralize 37.22 mL of 0.25M HCl?
What mass of calcium can be produced by this process if a current of 6200 {\rm A} is applied for 35 {\rm h}? Assume that the electrolytic cell is 69 % efficient. also What is the minimum voltage needed to cause the electrolysis
A bag of potato chips contains 595 mL of air at 30.0 degrees celcius and a pressure of 770 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 438 mL and the temperature is 8.00 celcius?
The vessel will contain gases at pressures up to 210.0 MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force o..
Answer the questions below with the data provided: 15 mL of 5% NaOH (w/v) is used to deprotonate the unknown carboxylic acid. The TBME is washed with an additional 10 mL of the NaOH solution and then 20 mL of water which are all combined.
A red laser pointer emits light with a wavelength of 650 nm. What is the energy (in J) of a photon of light of this wavelength?
An existing power plant has been found to produce SO2 concentration of 20?g/m3 at a distance of 800m directly downwind from the stack when the wind is 4m/s from the north during a class C stability situation.
Explain why a buffer made of equal concentrations of CH3COOH and CH3COO- does not change in pH when a small amount of NaOH (a strong base) is added to the solution. Does the NaOH dissociate into ions when it is added to the solution?
Consider a solution of a weak acid at a pH equal to its pKa. By how much would the pH change, and in which direction, if we added to this solution enough base to neutralize 10% of the total acid?
