Illustrate with a net ionic equation for each of the following how the pH would increase, decrease, or stay the same with the indicated changes: (b) Adding ammonium nitrate to a solution of ammonium hydroxide
A 9.70-g piece of solid CO2 (dry ice) is allowed to sublime in a balloon. The final volume of the balloon is 1.00 L at 298 K. What is the pressure of the gas?
Standardization of Na2S2O3, Added 0.12 g KIO3 and dissolved in 75 mL of distilled water. Added .20 g of KI to solution, then added 10 mL of 1M HCl and immediately titrated with thiosulfate solution (made by weighed 25 g of Na2S2O3-5H20
Experimental procedure, part A. whats is the procedure for preparing 250 mL of 0.0210 M Na2S2O3 for this experiment from a 100 mL volume of standard 0.106 M Na2S2O3?
If carbon dioxide gas is collected over water at 25C and 775 torr, what is the partial pressure of the CO2? The vapor pressure of water is 23.8 torr at 25C.
Which of the following would be expected to have a bent (angular) shape?
Methane burns in oxygen to produce carbon dioxide and water. Burning of 22.00 g of methane in oxygen will produce how many moles
Carbon oxide (carbon (II) oxide) can be purified of oxygen impurities by having it react with cobalt (II) oxide. If the impure carbon oxide contains a volume of 1.5% oxygen, and if it reacts with cobalt (II) oxide at 250 °C and 500 kPa.
A proton in a linear accelerator has a de Broglie wavelength of 127 pm. what is the speed of the proton?
what percent of the fuel consists of the lighter isotope? Assume that the masses of the two isotopes are exactly 235 and 238 amu.
1.664 g of a solid white acid are dissolved in water and completely neutralized by the addition of 45.37 mL of 0.580 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.
Drag the flask and drop it on the lower half of the burette to connect them. Open the Data window and click on the flask. Click the Pushpin icon in the blue bar of the Data window to lock its display to the flask's contents.
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
