If possible just a brief explanation how you got the answer?
1) Depict the product of 3,3-dimethylhexanamide 2) Depict the prduct of gamma -caprolactam 3) Depict the product of gamma-methylcaproic acid
Calculate the mass of sodium hydroxide that must be added to 1.00 L of 1.00 M HC2H3O2 to double the pH of the solution (assume that the added NaOH does not change the volume of the solution)
At 521 K the value of Kp for the equilibrium represented by the balanced equation is 1.07 x 100. Calculate the value of Kc at the same temperature. Express answer in scientific notation.
If one mole of CO2 is produced in the subsequent reaction, explain how many moles of H20 are also produced.C3H8(g) +5O2(g) -----> 3CO2 (g) + 4 H20 (g)
Calculate the concentration in ppm of a pollutant that has been measured at 450 mg per 150 kg of sample.
Using the information given, write an expression which would give the solubility, S, as a function of the chloride ion concentration, [Cl-]. This means include all the equilibria.
What is the maximum concentration of fe3+ can a buffer solution that is .10M CH3COOH and .10M CH3COONa hold without forming any precipitate
Eather at room temperature is placed in a flask connected by rubber tubing to a vacum pump, and the pump is turned on, and the ether begins boiling. Explain.
If 2.00 mol of argon is mixed with 3.00 mol of xenon and the total pressure of the system is 860 torr, what are the individual pressures. what would be the volume of this mixture at 18.0 psi and 18.5 C.
When steam condenses to liquid water, 2.26 kJ of heat is released per gram. The heat from 168 g of steam is used to heat a room containing 6.44*104 g of air (20ft*12ft*8ft). The specific heat of the at normal pressure is 1.015 J/(g°C).
two determinations of the dissolved oxygen content of a 200 ml sample of water made five days apart gave 5.3 ppm and
