HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.077 M in NaClO?
What are the concentrations of the gases at equilibrium, if the initial concentration of carbon monoxide and water vapor are both equal to 0.325 M. Can you explain me what is the formula and how did you do it
Explain which of the following substance has the lowest melting point
Calculate the molar solubility of AgCl in a solution made by dissolving 10.0 g of CaCl2 in 1.50 L of solution.
Identical containers Ar, CO2, He, and Cl2 at the same temperature and pressure. Which has the lowest density?
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
A sample of the exit air is drawn in to a chamber containing a mirror and cooled slowly, keeping the gauge pressure at 10mm Hg. A mist is observed to form on the mirror at a temperature 40C. Calculate mass of water removed from ..
Suppose 50 mL of 0.020 M Hydhrochloric acid solution was mixed to 50 mL of 0.20 M acetic acid solution (Ka of acetic acid, CH3COOH, = 1.8 x 10-5). Determine the approximate pH of the mixture.
You will titrate a boric acid solution that has absorbed the ammonia from a soil sample. It is not necessary to know the exact volume or concentration of the boric acid. Explain why not
Based on the functional group(s) present in the two compounds, determine 3 physical properties for each of the two compounds. Using these physical properties determine how each of the two compounds uniquely function in the products in which they ar..
