Magnesium metal is used as a sacrificial anode to reduce the corrosion of underground storage tanks (made of iron, more accurately steel). As a result the sacrifical metal corrodes instead of iron. Explain
If 1.87 of acetic acid() reacts with 2.31 of isopentyl alcohol() to give 2.96 of isopentyl acetate(), what is the percent yield of the reaction?
Determine q for the acid-base reaction, assuming that the liquids have densities of 1.00 g/mL and the same heat capacities as pure water.
The three main components of dry air and the percentage of each are Nitrogen(78.08%), oxygen (20.95%), and argon (0.93) A) calculate the partial pressure of each gas in a sample of dry air at 760mmHg
Suppose that 0.680 mol IBr in a 2.50-L flask is allowed to reach equilibrium at 150.°C. What are the equilibrium concentrations of IBr, I2, and Br2? [Br2] ?? M [I2] ?? M [IBr] ?? M

Calculate the molar mass of the compound if given that normal freezing point of C6H6 = 5.5 oC , the freezing point depression constant for C 6 H 6 = -5.12 o C/m .
If the water in a well has 1000.0 mg/L of CaCO3 dissolved in it, How many grams of Na2C2O4 could you mix with 100.0 mL of that water before a precipitate would form
A solid sample weighing 0.2736 g of ethylammonium chloride appreciably contaminated with ammonium chloride (but no other contaminants) required 34.20 mL of 0.08177 M NaOH for complete titration. Find the weight percent of each component in the mix..
What is the change in the measurement of the potential if a solution of 1.00x10-3 M NaF is exchanged for another solution of 1.00x10-4 M NaF?
Blending of two wines with different concentrations of acid, Two wines are available for blending: One tank of 1000 L has a Titratable Acidity of 9.0 g/L and another tank containing 2000 L has a Titratable Acidity of 0.6 g/L.
Calculate the pressure of the gas mixture and the partial pressure of each constituent gas if the mixture is in a 11.0 L vessel at 27 degree celsius
