An electric field should exist inside a conductor that carries a current. Explain how is that possible in view of the fact that in electrostatics we concluded that the electric field must be zero inside a conductor?
For each of the subsequent reactions, indicate which substance is oxidized as well as which reduced. Explain which substance is the oxidizing agent and which is the reducing agent
What was the temperature of the sample after heating. Please show work I've asked this question before and I'm getting mixed answers.
A solution was prepared by dissolving 28.0g of KCl in 225g of water. Calculate the mass percent of KCl in the solution.
A system consists of 6.00 moles of benzene. It is initially at a temperature of 76.0°C, a pressure of 0.878 bar, and a volume of 534.7 cm3. Calculate the volume of the system at the end of this process.
Is it true that the effect of a catalyst on a chemical reaction is to react with product, effectively removing it and shifting the equilibrium to the right
Synthesized a new compound one which has never beenprepared. How would you determine its mp? What precautions could take to insure that it is as accurate as possible?
Using terms in the Hartree-Fock energy expression, explain why the lowest-energy triplet state of the He atom is higher in energy than the singlet state.
How many grams of urea (NH2)2CO must be added to 351 grams of water to give a solution with a vapor pressure of 2.73mmHg less than that of pure water 3 degrees celsius The vapor pressure of water at 30 degrees celsius is 31.8 mmHg
what has the lowest freezing point, pure water, aqueous .60m glucose, .60m sucrose, .20m iron iodide or .50m potassium chloride
A typical protein contains 16.2 wt% nitrogen (N). A 0.500 mL sample of protein solution was decomposed, and the liberated ammonia (NH3) was reacted with 10.00 mL of 0.02140 M HCl.
in the reaction below, 3.71 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) 2 HBr(g) Given that Kc = 84.1, calculate the equilibrium pressure of HBr.
