Ethanol (C2H5OH) is synthesized for industrial use by the following reaction, carried out at very high pressure.
C2H4(g) + H2O(g) ? C2H5OH(l)
What is the maximum amount, in kg, of ethanol that can be produced when 2.62 kg of ethylene (C2H4) and 0.0684 kg of steam are placed into the reaction vessel?
Determining System Equilibrium, A one-litre cylinder at 458'C is found to contain 0.36 moles of HI (g), 0.15 moles of I 2(g), and 0.18 moles of H2(g). Is this system at equilibrium?
In a second experiment, I(electric current) broke down a sample of H 2 O into 1.45 grams of hydrogen and 11.51 grams oxygen. Are these results reliable with the law of exact extent?
At equilibrium, it was found that [CH3COOH] = 0.8537 M, [CH3COOO-] = 0.0040 M and [H3O+] = 0.0040 M. Calculate the acidity constant of CH3COOH and the pH value of the solution.
A solution is 40% acetic acid by mass. The density of this solution is 1.049 g/mL. Calcu late the mass of pure acetic acid in 480 mL of this solution at 20 C
An unknown consisting of a single sugar gives a negative fermentation test. Which one of the following tests would allow you to decide which of the five sugars used in this experiment you had?
Given the following half-cell reactions, write the overall reaction and calculate the standard reduction potential for the cell. Mn3O4 (s) + 4H2O (l) + 2e- ? 3Mn(OH)2 (s) + 2OH- (aq)Eo = 0.002 V
What will be the likely effect of clearing forests and converting them to grasslands and crops on (a) the earth's reflectivity (albedo) and (b) the earth's average surface temperature?
The membrane has pores equivalent in size to a spherical molecule with a molecular weight (Mm) of 120,000 daltons. The protein solution consists of albumin (40 g/L at Mm = 69,000 daltons), globulins (70 g/L at MW = 150,000 daltons), and fibrinogen..
a flask that can withstand an internal pressure of 2500 torr, but no more, is filled with a gas at 21.O C and 780 torr and heated. At what temperature will it burst?
how does the technique error affect the report percent water in the hydrated salt? Explain lab 5 percent water in a hydrated salt.
Nitric oxide, oxygen, and nitrogen react by the following equation. 2 NO(g) N2(g) + O2(g)Kc = 2.3 10^30 at 298 K
The Environmental Protection Agency has estimated that 119 tons of mercury are currently emitted to Earth's atmosphere annually due to human activities
