Answer:
Magnesium (Mg) is able to bond with one oxygen (O) atom. The formula of the compound is MgO. You can see in the dot structure that the two atoms share four different electrons. When a bond is made with four electrons, it is called a double bond.
Explanation:
Answer: So basically we have to know does the material's characteristics/compositions affect its density?
Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.
The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
