For each of the following molecules, provide a Lewis structure, including resonance and formal charge. Predict the electron-domain geometry, the molecular geometry, and the hybridization of the central atom. For each non ionic species, state whether it will be polar or nonpolar. a) SeO2 b) XeF4 c) PCL5 d) BrF2-
Why is the structure of FMN and Coenzyme Q important for the function of the electron transport chain
at 80 degrees celsius the vapor pressures of pure liquids X,Y and Z are 385, 190,and 66 mm Hg, respectively. What pressure must be exerted on the surface of a solution containing one mole of X, three mole of Y, and two moles of Z for boiling to be..
A canister is filled with 310 g of ice and 100 g. of liquid water, both at 0 C . The canister is placed in an oven until all the has boiled off and the canister is empty.
A current of 5.64 A is pass through a Ni(NO3)2 solution. How long (in hours) would this current have to be applied to plate out 8.80 g of nickel
What percentage error would be introduced in a 35.0 mL sample of liquid if the air bubble comes out of the tip of the buret while the liquid sample is being transferred?
You performed this fractional distillation using an air condenser as the "fractionating" column. Explain why the distillate may have been obtained in higher purity if you would have used a fractionating column packed with glass beads.
A certain toilet cleaner uses NaHSO4 as its active ingredient. In an analysis, 0.500 g of the cleaner was dissolved in 30.0 mL of distilled water and required 57.4 mL of 0.00535 M NaOH for complete neutralization in a titration.
