The density of pure copper is 8.96 at 20°c. if 5.00 g of pure copper pellets is added to a graduated cylinder containing 14.6 ml of water, to what volume level will the water in the cylinder rise?

15.2 mL

Explanation:

First we calculate the volume of the copper

when this volume of copper is added to the water, the water level will rise by the level of the volume of copper. So the final volume is:

14.6 mL + 0.5580 mL = 15.158 mL

Since the measuring cylinder is graduated to one decimal place , we can round this up to 15.2 mL

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.

The orbital diagram of an orbit containing 16 electrons will be as follows:

    1s²2s²2p⁶3s²3p⁴

The maximum number of electrons in each sublevel of the orbitals are:                  2 electrons for s-sublevel with one orbital                  6 electrons for p-sublevel with three orbital                  10 electrons for d-sublevel with five orbital                  14 electrons for f-sublevel with seven orbital
