you have a buffer system made up of equimolar amount of carbonic acid,H2CO3, and sodium bicarbonate,NaHCO3. Write equations to show how this buffer behaves when (a) HCL is added and (b) NaOH is added.
Determine the concentration of a solution prepared by diluting 25.0 milliliters of a 12 molar HCl solution with H2O until the final volume is 2.50 x 10² milliliters.
Find out the exact significant figures for each of the values - Indicate the number of significant figures
You are given trhat 0.01 m aqueous solutions of each of the given solution as, C6H12O6, K3PO4, CaCl2 , NaI you jutst need to place the given solutions in order of increasing change in the freezing point of the solution.
A solution is prepared from 0.95 grams of H3PO4 ,(Phosphoric acid) and 1.15 grams of HClO4 (perchloric acid) in 150 mili litres of solution then determine how many milliliters of 0.425 M sodium hydroxide( NaOH) is needed.
Determine the second order rate constant from the initial concentration and half life and what is the second order rate constant?
For each reaction, calculate the mass (in grams) of the product formed when 10.1g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant.
