a) Consider a carbon atom in its ground state. Would such an atom offer a satisfactory model for the carbon of methane? If not, why not? (Hint: Consider whether a ground state carbon atom could be tetravalent, and consider the bond angles that would result if it were to combine with hydrogen atoms.)
b) Consider a carbon atom in the excited state. Would such an atom offer a satisfactory model for the carbon of methane? If not, why not?
Suppose that the calorimeter shown here was used to determine the energy change for an acid-base reaction. An acid/base reaction solution was made by combining 150 mL of 0.5 M HCl of 50 mL of 1.00 M NaOH, to make 200.0g of solution
What is the volume occupied by 25.6 g of argon gas at a pressure of 1.41 atm and a temperature of 411 K?
A quantity of ice at 0.0 degrees C was added to 33.6 of water at 21.0 degree C to give water at 0.0 degrees C. How much ice was added?
what elutes from the column when etc. Why do you think you use extraction techniques instead of chromatography?
Once the system has reached equilibrium, 5.00g of NO2 is injected into the vessel, and the system is allowed to equilibrate once again. Calculate the mass of N2O4 in the final equilibrium mixture.
A laboratory technician needs to make 500.0mL of a 0.25 M NaOH solution. What mass of sodium hydroxide does the technician need to use?
Distilled water is mixed in one test tube with 1) a soap made of NaOH and canola oil and 2) a separate test tube with just laundry detergent
Copper dissolves in nitric acid, producing copper (ll) nitrate. After reaction with sodium hydroxide and heating, copper nitrate changes to copper (ll) oxide. Calculate the percent yield of this process if 1.075 g of copper produced 1.075 g of cop..
