Question- If the Ka of a monoprotic weak acid is 4.5 x 10^-6, What is the pH of a 0.14 M solution of this acid?
Explain what magnetic field strength must be applied for C-13 spin transitions to occur at 90 MHz? magnetogyric ratio for C-13 = 6.728x107 rad.T-1.s-1
Hydrocarbons are often reacted with steam to form H2, as shown for propane: C3H8(g) + 6 H2O(g) 3 CO2(g) + 10 H2(g) Calculate Kp for this reaction at a particular temperature
determine what percentage (by mass) of the detergent must be sodium carbonate in order to completely precipitate all of the calcium and magnesium ions in an average load of laundry water.
Calculate the change in internal energy for a system if a gas cools and releases 10.86 kJ of heat and expanded from 2.35 L to 22.86 L at 3.50 atm
The volume of Ba2+ required to reach the endpoint is 22.40 mL. What is the calculated molar mass of the sulfate present in bottle A
256 grams of sodium chloride reacts with an excess of calcium oxide. How many grams of sodium oxide are produced?
calculate the amount of heat in joules (q) required to affect this temperature change and the total change in internal energy, ?U. Note that some books use ?E as the symbol for internal energy instead of ?U.
Potable water (drinking water) should not have manganese concentrations in excess of 0.05 mg/mL. If the manganese concentration is greater than 0.1 mg/mL, it imparts a foul taste to the water and discolors laundry and porcelain surfaces.
Find the equation for work of a reversible isothermal compression of 1mol of a gas in a piston cylinder assembly if the molar volume of the gas is given by V = [(RT)/P] + b; where R and b are positive constants.
AgBr is the light-sensitive compound in most photographic films. Assume, when film is exposed, that the light energy absorbed dissociates the molecule into atoms.
75.0 mL of a 1.80 M solution is diluted to a volume of 258 mL. A 129-mL portion of that solution is diluted using 187 mL of water.
Problem- A vessel with a volume of 32.5 L contains 2.80 g of nitrogen gas, 0.403 g of hydrogen gas, and 79.9 g of argon gas. At 25°C, what is the pressure in the vessel?
