What does VSEPR stand for? How can it be used to predict the geometry of a molecule? Give the electron and molecular geometry for the Lewis structures drawn above?
Given the following data table, use the method of initial rates to determinet the rate law for the following reaction: A + B = C + D + E run: ro(M/s): [A]o: [B]o: [C]o: [D]o: [E]o:
When you calculated k in the rate equation for the reaction of KMnO4 solution and H2C2O4 solution you assumed k had the same value under the conditions of determinations 1,2, and 3.
A solution containing toluene had a gas chromatographic peak area of 412420. While 0.7130g of this solution was spiked with 0.0178g of pure toluene, the signal was 731508. Explain what is the concentration of toluene in the original solution. Mass..
The compound Pb3O4 (red lead) contains a mixture of lead(II) and lead(IV) oxidation states. What is the mole ratio of lead (II) to lead (IV) in red lead
not enough air is pumped into a raft to completely fill it out. the atmospheric pressure is 14.7 psi. what is the pressure of the air inside the raft?
If oxygen gas were collected over water at 20 degrees C as well as the total pressure of the wet gas were 670 mm Hg, explain what would be the partial pressure of the oxygen
In all parts: assume the the speed of sound in air is 339 m/s. Suppose a ship's foghorn is sounded toward an iceberg, and an echo is heard 4.33 s later. What is the distance from the ship to the iceberg. Suppose the lab floor is 3.12 m beneath the..
theoretically feasible in a solution that initially 0.250 M in each ion? c.) If separation is feasibe in eithee (a) or (b), what ranfe of anode potential (vs. SCE) should be used?
A solution of I- gives 301.0 mV in a cell with an iodide ion selective electrode. 10.0 mL of the solution is mixed with 3.00 mL of 1.00 x10^-6 M AgNO3, and the Ag is completely precipitated as AgI. The cell then gives 310.2 mV. Assume the electrod..
