The volume of a block of iron is 9 cc and its mass is 70.83
g. what would be the volume of a block of aluminum that has the same mass as the block of iron? (the density of aluminum is 2.70 g/cc)

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
