How many grams of solid nickel will be deposited when an aqueous nickel(II) sulfate solution is electrolyzed for 10.5 min with a constant current of 3.2A?
Determine How many mg of a 298 mg sample remains unreacted after twenty three days if 32P decompose by a first-order mechanism, half-life = 14.3 days.
Calculate how many grams of Copper II carbonate are obtained when 5.2ml of an 3.0M aques solution of sodium carbonate is mixed with 10.0ml of a 5.0M aques solution of Copper II Nitrate.
A silver electrode of the first kind was used to measure the Ag+ ion concentration in solution. When the [Ag+] is 1.44 x 10-3 the Ecell is determined to be 0.626. Calculate the temperature (oC) using the Nernst equation.
When a solution containing 0.01 M sodium azide (NaN3) and 0.01 M iodomethane in methanol at 0° C is monitored kinetically, the results reveal that iodide ion is produced at a rate of 3.0 X 10-3 M L-1 s-1. Provide the product of this reaction and c..
A closed end manometer was constructed from a u-shaped glass tube which was 80.0 centimeters high. It was loaded with mercury so that the closed side was filled all the way to the top (80.0 cm above the neck)
consider a nonmetal atom which we will give the symbol x. the element x is a gas at room temperature and can easily
Compute the amount of solid NH4Cl to add to 60ml of .1M ammonia to form a mixture that has the desire pH (9).
A buffer solution was prepared by adding 4.95 g of sodium acetate (NaCH3CO2) to 0.250 L of 0.150 M acetic acid (Ka = 1.75 x 10-5). What is the pH of the buffer
Define the phase diagram for acetic acid given the following information triple point at 289.7K as well as 1.29kPa critical temperature = 590.7K critical pressure = 5.78MPa freezing point is 289.8K at 0.1MPa.
A sample containing 4.80 g of gas has a volume of 15.0 L. Pressure and temperature remain constant. What is the new voume if 0.500 mole gas is added?
What is the maximum strength of acetic acid waste ( as TOC in mg/L) that can be discharged without violating either permit requirement. ( recall that TOC in mg/L , measures the number of miligrams of carbon per liter)
Dry air near sea level has the subsequent composition by volume N2, 78.08 percent; O2, 20.94 percent; Ar, 0.93 percent; CO2, 0.05 percent. The atmospheric pressure is 1.00 atm. Since volume is proportional to the number of moles present mole fract..
