Calculate the hydrogen ion concentration in a solution containing 7.89 g of strontium hydroxide in 600 mL of solution.
Use Hess' Law to show how the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion.
The activation energy of a certain reaction is 44.5kJ/mol. At 21, the rate constant is0.0110 s^-1 . At what temperature in degrees Celsius would this reaction go twice as fast?
Draw expected results if powder samples of Al2O3 and SiO2 are studied using TG and DSC in the temperature range of 30 - 1500 oC.
A solution is prepared by dissolving 1.00 g of Compound B in enough water to create 250.0mL of solution. What is the molarity of Compound B in this solution?
As the bubble rises to the surface, the pressure decreases and the volume of the bubble therefore increases. The temperature of the water is constant. Find the final volume of the bubble if its initial volume is 11.7 cm^3.
