What are some factors to help you determine the relative strength of a base? For example, how would you know that NH2- is a very strong base? Or that OH- is a weaker base than NH2-? And that CN- is a relatively weak base?
dependent Schrodinger equations of a particle with mass m confined in the one-dimensional potential (1/2)kx^2 , where k is some constant.
Write chemical equations showing how each of the following weak bases ionizes water to form OH-. With NH3
Calcium supplements commonly contain calcium ions in the form of calium carbonate (CaCO3). If one calcium supplement weights 600. mg, how many moles of calcium are contained in each pill
If 31.82 g of a metal oxide reacted with excess carbon and 4.08 L of CO2 formed at 100 C and 1.5 atm what is the identity of the metal
Does this verify that only a single detergent compound is in the extract. What specifically can you do to gain more information about the composition of the shampoo extract
1) Many household cleaning products contain oxalic acid H2C2O4, , a diprotic acid with the following dissociation constants: Ka1=5.9E-2 and Ka2=6.4E-5 Calculate the equilibrium concentration of C2O4^2- in a 0.20 M solution of oxalic acid
What is the value of the equilibrium constant for Haber process at 298K if the equilibrium concentration are as follows:
Why does this calculation only provide an estimate of the NaOH concentration. In other words, why do we have to standardize the HaOH in this experiment to find its exact concentration
Consider a saturated solution of calcium fluoride in 0.039 M potassium nitrate. Complete the following tasks, and then answer the question.
Rates of reactions: Rate = k [A]^m [B]^n where the reaction time = 1 / Rate. Two chemical experiments were performed to determine the exponent "n". (We will assume that "m" is known).
Calculate the molar concentration of OH- ions in a 0.560 M solution of hypobromite ion (BrO-; Kb = 4.0 x 10^-6). What is the OH- and PH
A 0.4000 g sample that contained 96.4% Na2SO4 (142.04 g/mol) required 41.25 mL of barium chloride solution to reach the endpoint in a precipitation titration. What is the molarity of the BaCl2 solution
