Using the inverse square law of radiation, what Geiger counter reading would you get for a radioactive material when you are 3 feet from the source (assume an initial reading of 6300 R at a distance of 1 foot from the source)?
Consider: C7H16 (l) + 11 O2 (g) → 7 CO2 (g) + 8 H2O (l) ΔH°reaction=- 4130 kJ. How much energy is released when 4.000 moles of C7H16, is combusted?
C2H4 + 3O2 = 2CO2 + 2H2O if you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be produced.
Starting with 2-methyl-1,3-cyclohexanedione and other appropriate reagents, provide a mechanism for a Robinson annulation reaction.
Calculate the energy necessary to boil 100.0 g carbon disulfide, CS2, at its normal boiling point.
If you have a 0.1M solution of weak acid X (pKa 3.5) and another 0.1M solution of weak acid Y (pKa 4.3), which solution would have the lower pH?
A weather balloon is inflated to a volume of 26.5L at a pressure of 735mmHg and a temperature of 24.5 degreed C. The balloon rises in the atmosphere to an altitude, where the pressure is 390.mmHg and the temperature is -13.9 degrees C.
