The radius of a copper (cu) atom is roughly 1.3 x 10^-10 m. how many times can you divide evenly a 10-cm-long piece of copper wire until it is reduced to two separate copper atoms? (assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. round off your answer to an integer.)

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.
