Adding ammonia to a solution containing copper ions... Answer can be multiple removes the copper from the solution by forming a precipitate. increases the copper concentration by shifting the reaction toward the reactants. causes formation of a complex ion with the copper. reduces the copper to copper metal.
Calculate the spring constant of this silicone band including units. I know Hooke's law is F=-KX, where F is force, -K is the consent of the spring which I need to find and X is the displacement from relaxed position, but i'm giving the oscillatio..
Calculate the pH during the titration of 20.00 mL of 0.1000 M CH3CH2COOH(aq) with 0.1000 M NaOH(aq) after 20.39 mL of the base have been added. Ka of propanoic acid = 1.3 x 10-5.
Predict the fraction of octahedral holes and tetrahedral holes that are filled by the various cations. octahedral holes filled with aluminum ions and tetrahedral holes filled with magnesium ions.
When making an alcoholic beverage, such as beer and wine, Brix is a measurement used to assess the amount of sugar present in the fermentation matrix or grape juice.
What is the possible chemical explanation for this? I understand that a reaction using a thiamine catalyst at room temperature for 48 hours may lead to lower yield due to catalyst decomposition, but I'd like to know a more technical explanation.
What molarity of aqueous calcium chloride solution can be expected to show the same conductivity as 0.0050 M aluminum sulfate at 12,500 units.
From the first and second laws of thermodynamics, derive the equation for the criterion of spontaneity of a process, Gibbs free energy,
