HCl, HBr, and HI are strong acids, yet HF is a weak acid. What does that mean in terms of the extent to which these substances are ionized in solution?
if the partial pressure of cyclopropane in the misture is 330 mm Hg and the partial pressure of the ocygen is 1.0 atm, what is the total pressure of the misture in torr?
Nitrogen Oxide is a pollutant in the lower atmosphere that irritates the eyes and lungs and leads to the formation of acid rain. Nitrogen oxide forms naturally in the atmosphere according to the following endothermic reaction
If the initial pressure of the ether is 135 torr, what is its partial pressure after 1420 s? (Note, since the volume and temperature don't change, the pressure is directly related to number of moles and so the pressure can be treated similar to co..
What is the value of rate constant k? b.) What is the half life of the reaction? c.) What concentration will remain after 25 minutes?

The change in the Gibbs energy of a certain constant-pressure process as a function of temperature was found to fit the expression ?G (J K-1)=-73.1 J +42.8T. Calculate the value of S for the process.
Write down a lewis structure for SbCl5 and also explain Does the the octet rule is obeyed by this molecule Explain how many grams would 3.01 * x10 23 atoms of tellurium have?
a sample of beach sand contains sand particles of different colors small pebbles and also shells. each component
Calculate the mass of methane that must be burned to provide enough heat to convert 151.0 g of water at 43.0°C
The overall hydrogen burning reaction in stars can be represented as the conversion of four protons to one alpha particle. Use the data for the mass of H-1 and He-4 to calculate the energy released by this process.
