The equilibrium constant Kp for the reaction ; CCl4(g) C(s) + 2Cl2(g) at 700 celcius is 0.76 atm. Determine the initial pressure of carbon tetrachloride
Rank a series of molecules by expected solubility in water based on polarity and hydrogen bonding. Some slightly soluble compounds are included in this exercise.
What volume of a concentrated HCl solution, which is 36.0% HCl by mass and has a density of 1.179g/mL , should be used to make 4.95 L of an HCl solution with a ph of 1.5?
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP.
A solution has a volume of 2.0 L and contains 36.0 g of glucose. If the molar mass of glucose is 180 g/mol, what is the molarity of the solution
Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to UV radiation, producing chlorine a..
