Based on what you have learned about intermolecular forces, would you say that matter is fundamentally attracted or repulsed by other matter?
if 625g of fe3o4 is produced in the reaction, how many molecules of hydrogen are produced at the same time?
The pH at one-half of the equivalence point in a weak acid-strong base titration
Now you find yourself on an airplane headed for Israel to visit the Dead Sea, which is below sea level. You have always wanted to visit there and now is your chance. What has happened to the atmospheric pressure?
An equilibrium mixture contains 0.750 mol of each of the products (carbon dioxide and hydrogen gas) and 0.200 mol of each of the reactants (carbon monoxide and water vapor) in a 1.00-L container.
Determine the molar mass of the acid and given that the pH at the half way point to the equivalence is 3.86. Calculate the Ka of the unknown acid.
which indicator is more accurate phenopthalein or methyl orange? why
starting with ethyne and any alkyl halide with four or fewer carbons, any needed inorganic reagents, show how you would synthesize the following compounds
Calculate the pH at each of the following points in the titration of 50 mL of 0.2000M acetic acid using 0.222M NaOH. Ka= 1.8 x 10^-5 (show work)
A 2.154 g sample of HgO produces 125 mL of oxygen gas. The gas is collected over water at 24 C and an atmospheric pressure of 763 torr.
A reaction vessel contains these compounds at equilibrium. What will happen if the volume of the container is reduced by 50% at constant temperature?
Describe the two methods for determing the volume of the vapor In a Molar Mass of a Volatile Liquid experiment? Which method is likely to give more precise results? Why?
