Ответ:
Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.
Explanation:
Ответ:
Iron has two ionic states of +2 and + 3. The formula for iron oxide with the Fe + 2 is FeO. The formula for iron oxide with The Fe+3 is Fe2O3. Using the atomic mass of Fe as 55.845 gr/mole and O as 15.999 gr/mole the percent Fe of FeO is 77.73% and of Fe2O3 is 69.94%.
