A student prepared a solution of sodium carbonate by 2.111g of the solid to a 250.0ml volumentric flask and adding H2O to the mark.
Some of this solution was transferred to a burett - What volume of solution should the student transfer into a flask
An aqueous solution contains 545 g of ThCl3. If the solution is electrolyzed using inert electrodes, calculate the current needed to remove all of the thorium from the solution in 5.00 hours.
In the electron transport chain, electrons from FADH2 are eventually used to reduce O2 into H2O. Experimentally, the proton motive force created by this process will generate 2 ATP molecules from ADP and Pi, using ATP synthase. From the informatio..
