Calculate the volume in liters of a 8.75x10^-5 M silver (II) oxide solution that contains 200.g of silver (II) oxide . Round your answer to 3 significant digits.
A cylinder of oxygen gas contains 26.4 g of O2. Another cylinder, twice the volume of the cylinder containing oxygen (and at the same conditions of pressure and temperature), contains CO2 gas.
The boiling points of HCl and CO2 are nearly the same (-85 degrees C and -78 degrees C). Explain why CO2 can be removed from an aqueous solution by boiling briefly while essentially no HCl is lost even after boiling for one hour or more
The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reach..
A 250.0 mL sample of chlorine gas is collected when the barometric pressure is 798 mmHg. What is the volume of the sample after the barometric pressure dropped to 745 mmHg?
Based on the sign of E°cell, classify these reactions as spontaneous or nonspontaneous as written. Assume standard conditions.
Give the reaction products of sodium borohydride (followed by acidification) with the following compounds. a) acetone
In a 1.00 L flask, 3.40 atm of CO reacts with 2.60 atm of O2. Assuming that the temperature remains constant, what is the final pressure in the flask.
Predict the direction of the reaction when chlorine gas is added to an equilibrium mixture of COCL2, CO, and CL2. The reaction is COCL2(g) CO(g) + Cl2 (g)
calculate the E cell when [Zn^+2] = 0.10M and [Cu^+2] = 2.0 x10^-4M. Is the reaction Spontaneous or Non- spontaneous?
Suppose that ammonia (a monoprotic base), applied to a field as a fertilizer, is washed into a farm pond containing 3.0 × 106 L of water. If the pH of this pond is found to be 9.81.
the red lice in the hydrogen spectrum is caused by the electron moving between which two energe levels? (the ionization energy of a hydroge atom is 2.18X10^-18J)
Aqueous solutions of each of the following salts {sodium acetate, sodium phosphate, sodium formate, and sodium carbonate} have a pH that is > 7. The reason for this is that the anion undergoes a so-called "hydrolysis reaction".
