How would you expect the H−X−H bond angle to vary in the series H2O, H2S, H2Se ? (Hint: The size of an electron pair domain depends in part on the electronegativity of the central atom.) Rank from largest to smallest angle. To rank items as equivalent, overlap them.

Provide a stepwise curved arrow mechanism that fully explains the outcome of the reaction shown below. oh нао* heat он

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
