A 53 g sample of impure KClO3 (solubility = 7.1 g per 100 g H2O at 20 degrees C) is contaminated with 13 percent of KCl (solubility = 25.5 g per 100 g of H2O at 20 degrees C).
(a) Calculate the minimum quantity of 20 degrees C water needed to dissolve all the KCl from the sample in grams.
(b) How much KClO3 will be left after this treatment? (Assuming that the solubilities are unaffected by the presence of the other compounds)
Calculate the pH of the solution that results from adding 28.0ml of 0.100M NaOH to 50.00 mL of a 0.0500 M solution of hydrochloric acid
calculate the wavelength of the emitted radiation if an electron in a hydrogen atom went from n = 4 to n = 1. in what region of the electromagnetic spectrum(e,g.X-ray, visible, infrared) would this radiation lie?
How much NaOH in grams is needed to prepare 546 mL of solution with a pH of 10.00? The molecular weight of NaOH is 40.0 g/mol. Hint: Since NaOH is a strong base it ionizes (disassociates) completely. The OH- concentration equals the initial concen..

Under what conditions would all three hydrogens be removed from H3PO4. I think it would need a strong base and high molarity.
What is the maximum height, neglecting all forms of friction, to which a car of mass 1000 kg can be driven on 1.00 gallon of fuel given that the engine cylinder temperature is 2000 C and the exit temperature is 800 C?
Complete and balance an equation describing each of the above reactions. (Use the lowest possible coefficients. Omit states-of-matter in your answer.)
Which is the best description of hydrogen bonding? The temporary attraction between hydrogen atoms on different molecules resulting from shifts in electron density The association between a hydrogen atom which is somewhat positive because it is bo..
