A student in Chem 108 reacted a 0.367 g piece of Mg with excess silver nitrate according the equation below. The student isolated and weighed the silver metal produced, collecting 2.74 g of silver.
Mg (s) + 2 AgNO3(aq) → Mg(NO3)2(aq) + 2 Ag (s)
A) Determine the actual yield of silver formed.
B) Determine the theoretical yield.
C) Determine the percent yield,
Calculate the pressure of the gas if its volume is changed to 891 mL while its temperature is held constant. a) The pressure is 0.00253 atm. b) The pressure is 0.00428 atm. c) The pressure is 0.635 atm. d) The pressure is 1.57 atm. e) The pressure..
The gas remaining in the first container shows a pressure of 1.710 atm. Calculate the volume of the spherical container.
The subsequent names are all incorrect or incomplete, however they represent real structures. Depict each structure and name it correctly.
Consider the experiment where Cu is added to a solution acidic nitrate ion (look for a half reaction with nitrate). In the balanced equation, what is the coefficient in front of Cu
This precipitate is filtered off and a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed.
