Explanation:
Given a food with a relative humidity of 81%, what is the water activity of that food?
The water activity of a food can be determined by using the formula:
water activity=relative humidity of food / 100
Answer:
Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.
Arrow and line diagrams show the spin of electrons and show every orbital.
Written configurations require minimal space and show the distribution of electrons between subshells.
Explanation:
Answer:
Therefore, the partial pressure of oxygen at high altitudes is less than at sea level.
Explanation:
The deep ocean thus has higher oxygen because rates of oxygen consumption are low compared with the supply of cold, oxygen-rich deep waters from polar regions. In the surface layers, oxygen is supplied by exchange with the atmosphere.
