Atomic energy is the energy in the nucleus of an atom of electrons and their shells in chemical bonds of elements and compounds

How many moles is 14.5 cm^3 of platinum? the density of platinum is 21.45 g/cm^3.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

When microscope slides are stained to show blood cells, the small red blood cells that appear on the slides are much numerous than the large white blood cells. this supports the concept that
