If you mean: "genetic isolation" (not: "reproductive isolation"????);
then, this is an example of: "ecological isolation"; or, "geographic isolation" .

Rubidium is a chemical element with symbol Rb and atomic number 37. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with a standard atomic weight of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidationin air. On Earth, natural rubidium comprises two isotopes: 72% is the stable isotope, 85Rb; 28% is the slightly radioactive 87Rb, with a half-life of 49 billion years—more than three times longer than the estimated age of the universe.
aluminum element is more reactive than rubidium (Rb)
Answer:
Both are right
Explanation:
A constant heat must be supplied for several minutes to soldering gun to overcome the melting point of solder. A butane torch is a type of soldering device powered (energised) by the burning of butane gas to melt and solder common metals
If it is Mg2N2, and the limiting element is Mg, then the mass of Mg2N2 that can be produced is 50g/2 = 25 grams.
if it is Mg3N2, then the mass is 50/3 = 16.67grams.
Answer: 295.46g
Explanation: please see attached file for explanation.
