The answer is “the sustainability of the ecosystem” because if the ecosystem isn’t sustainable enough for many different organisms to live in it then the biological diversity of the ecosystem will decrease.
Answer:
20.1 g
Explanation:
The solubility indicates how much of the solute the solvent can dissolve. A solution is saturated when the solvent dissolved the maximum that it can do, so, if more solute is added, it will precipitate. The solubility varies with the temperature. Generally, it increases when the temperature increases.
So, if the solubility is 40.3 g/L, and the volume is 500 mL = 0.5 L, the mass of the solute is:
40.3 g/L = m/V
40.3 g/L = m/0.5L
m = 40.3 g/L * 0.5L
m = 20.1 g
A Lithium atom that has lost ONE Electron, is called a Lithium Ion (Li+).
answer a) the existence of isomers is a reason for the large number of carbon compounds
Answer:
1. Ar, Cl, Al, Mg, Na
2. O, S, Se, Te, Po
Explanation:
Just remember the trends. From left to right, atomic radius decreases because proton increases and pulls electrons closer. From top to bottom, atomic radius increases because there are more electron shells.
