Answer:
D
Explanation:
Both A and D are correct, because they will adapt from natural selection. Over time they will overcome the challenges of the new soil and be fine. however a few will die, but the best answer is D.
Sr is the limiting reactant.
Given the reaction equation;
2Sr + O2 (g) → 2SrO
2 moles of Sr reacts with 1 mole of O2
2 moles Sr will react with x mole of O2
x = 2 ×1/2
x = 1 mole of O2
Since we have more O2 than required, it is the reactant in excess, hence Sr is the limiting reactant.
