1. You are playing with a helium balloon on a typically nice fall day in Fullerton; CA. Suddenly the Celsius temperature doubles. How would the volume inside the balloon change?
2. Consider a gas at 1.00 atm in a 5.00 L container at 20OC. What pressure does the gas exert when transferred to a volume of 3.53 L at 43OC?
How many milliliters of O2 gas at 25 C and 1.00 atm pressure are obtained by the thermal decomposition of 0.470g of KMnO4? The balanced equation for the reaction is:
The atmospheric sulfur dioxide concentration over a certain region is 0.12 ppm by volume. Calculate the pH of the rainwater due to this pollutant. Assume the dissolution of SO2 does not affect its pressure.
45 mL of 0.016 M NaOH are added to 37 mL of 0.035 M HCL. The acid and base react to form NaCl and water. Assuming that the total volume of the mixed solution is 82 mL, compute the molarity of the final HCL solution.
when elemental sulfur is heated with a gas forms that contains only sulfur and fluorine. the following tests were
When you heat up popcorn, it loses water explosively and it pops. suppose a kernel of corn, weighing 0.125 grams weighs only 0.106 grams after popping.
At what Kelvin temperature will the reaction proceed 3.50 times faster than it did at 351 K?
On the basis of their positions in the periodic table, select the atom with the larger atomic radius in each of the following pairs.
Which of the following atoms has the smallest radius? At, Br, Ge, or Pb? Which of the following atoms has the smallest radius? At, Br, Ge, or Pb? The answer is Ge. Based on trends, wouldn't Br have a smaller atomic radius than Ge?
The difference between the transition state and the energy of the products. C. The difference between the energy of the products and the energy of the reactants. D. Undefined because it depends on whether the reaction is endothermic or exothermic.
chromatogram for the presence of compounds other than isopentyl acetate. Explain the presence of any additional compounds
A cylinder is separated into two sections Y and Z by an insulating frictionless piston and sealed at both ends. Each section has two moles of an ideal gas.
find the volume of aqueous acetic avid required to prepare an effective buffer solution when 8.2 grams of sodium acetate is used. Assume 500mL is required for the buffer solutions and also find the pH of the buffer.
