306 ml of a 0.208 M solution of silver nitrate will react with 146 ml of a 0.170 M solution of sodium phosphate to produce how many grams of silver phosphate precipitate. The balanced reaction is: 3AgNO3 + Na3PO4 ---- Ag3PO4 +3NaNO3
You take 1 ml of your sample and dialyze it in 1000 ml of buffer. At the end of dialysis what is the concentration of (NH4)2SO4 in your sample. How could you further lower the (NH4)SO4 concentration
Using the information from question 1, what are the stoichiometric coefficients for the reactant and products if you leave water as the last product
what is the mass in grams in 2.28 mol of each of the following: a) N2, b)SO3, c)C3H6O3, d)Mg(HCO3)2, e)SF6. Please use significant figures.
Recommend an explanation why the cyclic intermediate might have two important groups in a trans relationship that could factor the E-alkene.
D-maltose is a disaccharide and D means the OH on the second to last carbon to the bottom is on the Right and L means left how do we draw a structure of D-maltose or alpa-D-maltose
What is the molar mass of the acid? If the unknown acid had the formula H2X, could this experiment be used to determine its molar mass? Explain why or why not
An aqueous solution is 5.80% methanol (CH3OH) by mass with d= 0.988 g/ml. What is the molarity of CH3OH in this solution
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.13 mL of 0.08840 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.18 mL. Determine the percent WO3 in ..
A 0.2254 g sample of naphthalene (C8H10, 128.16 g/mol) was burned in a bomb calorimeter with a heat capacity of 2.18 kJ/K, and the temperature increased by 4.16°C. What is the molar enthalpy of combustion for this compound
Which one of the following is not a redox reaction?
Calculate the pH of a solution made by mixing 2.0 M HF and 2.0 M HCN. Also calculate the concentration of CN- ion at equilibrium.
You may use expanded, condensed, or line structures, provided they are neat and legible. If you could not identify one of your components, then pick an appropriate component from the list of unknowns.
