Research and discuss the Rutherford experiment. Please describe how it was performed and what was concluded from the results and why. Some ideas:
Go further and tell a classmate more information about Rutherford.
Discuss how this theory relates to the atomic theory.
you are asked to go into the lab and prepare an acetic acid-sodium acetate buffer solution with a ph of 4.40 plusmn
Use a table of standard thermodynamic values to predict the standard cell potential at 81 C: Cu(s)|CuSO4||AgNO3|Ag(s) Assume that the values of ?H and ?S are independent of temperature.
Consider the decomposition of calcium carbonate. Assume that ?H° = 177.8 kJ/mol and ?S° = 160.5 J/K·mol for the temperature range.
Assume a wind turbine with a hub 50 meters above the ground, a rotor diameter of 75 meters and a wind-conversion efficiency of 25 percent.
What are the 8 balanced molecular equations for all of the chemical reactions involved in the copper cycle experiment
you have dissolved 0.298 g of soda ash into 80 mL of deionized water. It took 19.8 mL of 0.0998 M HCl to titrate the solution to the second equivalence point. What is the percent Na2CO3 in the soda ash?
At 298, 1 atm, the heat produced by the reaction of 4.00mol of NO with molecular oxygen heats 1.07L liquid water from 298k to 348k. Calculate enthalpy for the reaction 2NO + O2 -> NO2, at 298k. Assume constant pressure and no heat lost.
A gas is compressed from 68.2 L to 8.0 L at 0.70 atmospheres? In addition a total of 3300 J of heat are gained from warmer surroundings. What is the change in internal energy in kJ
85.50 mL of 0.0815 M sodium hydroxide is reacted with 8.15 g oxalic acid as shown in the reaction below. What mass of the excess reactant remains after the reaction is complete
a tightly sealed 5.0 l flask contains argon at 71.6 deg. c and 781 mm hg. the flask is heated until the pressure is
Calculate the pre-equilibrium concentration of Fe3+(aq) in a solution made by mixing 2.8 mL of 2.010?3 M Fe(NO3)3 and 7.2 mL of 2.010?3 M NaSCN. Assume the final volume is 10.0 mL.
Show that the balanced equation obeys the law of conservation of mass.
