A volume of 89 mL of H2O is initially at room temperature (22.00 oC). A chilled steel rod at 2.00oC is placed in the water. If the final temperature of the system is 20.39oC, what is the mass of the steel bar?
Use the following values: specific heat of water = 4.18 J/(goC); specific heat of steel = 0.452 J/(goC)
A solution contains some or all of the ions Cu^{2+}, Al^{3+}, K^+, Ca^{2+}, Ba^{2+}, Pb^{2+}, and {NH_4}^+. The following tests were performed, in order, on the solution
A 10.0-mL solution of .510 M NH3 is titrated with a .170 M HCl solution. Calculate the pH after the following additions of the HCl solution.
Explain what is the fraction of association (α) for the subsequent potassium propionate solutions? Ignore activities. The Ka of propanoic acid is 1.34 × 10-5.
The purification unit can remove three-fourths of the DMF from the combined feed to the unit. Calculate the mol fraction of DMF entering the purification unit and the recycle ratio (recycle ratio = moles in recycle/moles in feed).
Calculates the atom economy and reaction efficiency of your synthesis of isopentyl acetate. b) Tell how the procedure of isopentyl acetate might be modified to increase the reaction efficiency. c) Describe some green features of your syntheisi, an..
Bleach is a dilute solution of NaOCl in water. The density of bleach is 1.05g/ml. If the percent by mass of NaOCl is 6% what is the [NaOCl]
Boron shows anomalous behaviour in its groups because of its small size and non-availability of d orbitals. It resembles silicon, the second member of the next higher group.
A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 200°C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar a..
Given the equilibrium constant,Kc=49.5, at the experimental temperature, calculate the equilibrium concentrations of H2(g),I2(g), and HI(g).
