At 50 degrees C, the value of pKw (the dissociation constant for water) is 13.262. Calculate the pH of water at this temperature.
1.0 mol of CaCN2 and 1.0 mole of water are mixed together: CaCN2 + 3 H2O → CaCO3 + 2 NH3 How much NH3 could be produced?
What is the pH of a solution made by adding 6.21 grams of sodium fluroide, NaF, to 391 mL of 0.317 M hydrofluoric acid, HF? (Assume no change in volume takes place.)
The partial pressures of gas A and gas B, respectively, are 0.379 atm and 0.675 atm. If 0.190 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
A gas at 89 degrees celcius occupies a volume of 0.67 L. At what kelvin temperature will the volume increase to 1.12 L. ?
The heat capactiy of the calorimeter is 1630 J/degrees celsius, and the inital temperature was 24.58 degrees celsius. What was the final temperature in degrees celsius?
How many kilograms of methane (CH4) are in perfectly insulated piston with the following properties: Volume = 2 cubic meters.
After the Ketone react with sodium borohydride in ethanol. HCl be added dropwise, and then remove the ethanol by distillation, then add DCM and ice water.
A 51 kg person drinks 400. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 15% of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake?
