A solution is made by dissolving 3.35 grams of an unknown salt in 150 mL of water at 22.5 deg C, and the temperature of the water rose to 23.81 deg C. Addition of silver nitrate solution results in a precipitate. Assuming that the heat capacity of the solution is the same as pure water, use enthalpies of solution and solubility rules to identify the salt.
Calculate delta S0 for the following processes: a.) Heating 1 mol of benzene(liquid) from 298K to 353 K at 1 bar pressure, neglecting any T- dependence of Cp.
A chemical reaction releases 58,500 J of heat into 150 g of water. Assuming no heat is lost to the surroundings
If we have a solution that contains 0.022 M Calcium and 0.014 Magnesium and we have to use potassium hydroxide to selectively precipitate one of the ions, while leaving the other ion in the solution.
You mix 50 ml of a weak monoprotic acid with 50 ml of NaOH solution in a coffee cup calorimeter. Both solutions and the calorimeter were initially at 22 C.
Draw the Lewis structure for C1F 2 + (small s at bottom and small + at top) What are its electron-pair and molecular geometries? decribe the bonding in the molecule in terms of hybrid orbitals.
Write the structures of all the alkenes that can be formed by dehydrohalogenation of each of the following alkyl halides.
How many L of H2 gas (at STP) is produced from 470 mL of 0.36 M HCl and excess Zn? The reaction is: Zn + 2HCl = ZnCl2 + H2
A 1.00 L sample of chlorine gas at 1.00 atm and 298 K reacts completely with 1.00 L of nitrogen gas and 2.00 L of oxygen gas at the same temperature and pressure.
A chemical reaction in which the atoms of the reactants undergo a change in the oxidation state is called a redox reaction. Such involve both oxidation (increase in oxidation state) and reduction
Two vessels are labeled A and B. Vessel A contains NH3 gas at 73 degrees C and vessel B contains Ne gas at the same temperature. If the average kinetic energy of NH3 is 7.1 10-21 J/molecule at 70 degrees C.
It takes 54.0 J to raise the temperature of an 11.7 g piece of unknown metal from 13.0C to 25.0C}. What is the specific heat for the metal?
what hybrid orbitals are used about the central atom of each of the angles.
