Draw its lewis structure, with the lone pair electrons, with the formal charges minimized? NO4 3-
The flask was then shaken until the solution was uniform. A 30.0-\rm mL sample of this glucose solution was diluted to 0.500 \rm L. How many grams of glucose are in 100. \rm mL of the final solution
400 M formic acid (HCOOH) solution freezes at -0.758 degrees C. Calculate the Ka of the acid at that temperature. (hint: assume that molarity is equal to molality. Carry out your calculations to three sig figs and round off to two for Ka).
We did a lab on equilibrium and le chatelier's principle. On one portion, there was a copper complex, and we had to add different components to a solution and write down the changes that took place
There are 3 different possible structures (known as isomers) for a dibromoethene molecule, C2H2Br2. One of them has no net dipole moment, but the other two do. Draw a structure for each isomer. Include H atoms.
Determine the molar concentration of the original acid solution and find pH and a % ionization of the acid in the original solution.
Calculate the pH of the following solutions with the given [H+] or [OH-] and indicate whether the solution is acidic or basic
Chlorine gas can be made in the laboratory by the reaction of hydrochloric acid and manganese (IV) oxide.
