Need chem with apex learning. what direction do you predict the addition of a base to the solution containing bromophenol blue will drive the equilibrium? explain your prediction in terms of le châtelier's principle.

How many grams of n2h4 will be consumed by 23 g of n2o4

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?

Achemist reacted 57.50 grams of sodium metal with an excess amount of chlorine gas. the chemical reaction that occurred is shown. na + cl2 → nacl if the percentage yield of the reaction is 86%, what is the actual yield? show your work, including the use of stoichiometric calculations and conversion factors.
