How many grams of butane must be burned to provide the heat needed to melt a 85.0-g piece of ice (at its melting point) and bring the resulting water to a boil (with no vapourization)? Assume a constant pressure of 1 bar and use the following data
Write a nuclear reaction for the neutron-induced fission of U-235 to produce Te-137 and Zr-87? How many neutrons are produced
predict a shape of small organic molecules that could bind tightly with G4. Be sure to explain your reasoning in terms of the measured distances and discuss the likely intermolecular forces involved in the interaction.
what is the molarity of a solution containing 7.0 moles of solute in 4300 mL of solution?
however, it takes more CaCl2 to form a White solid in one of the solutions than the other. Using the data from your experiment to help, explain what is happening when CaCl2 is reacted with the NaHCO3 (aq) or Na2CO3 (aq) solutions.
Sulfur dioxide (SO2) is an unwelcome result of burning soft coal in power plants. Some of the SO2 ends up as sulfuric acid in acid precipitation.
Find the activity(not the activity coefficient) of the (C3H7)4N+ (tetrapropylammonium) ion in a solution containing 0.005 M (C3H7)4N+Br- plus 0.005 M (CH3)4N+Cl-. The ionic strength will be affected by mixing
