I would say B because c and d would decrease competition and a would do the same, or just kill the ecosystem.
Hope this helps and don't forget to hit that heart :)

Answer:
0.0178
Explanation:
because you can work out the amount of moles in KOH using moles = mass/mr.
The mr of the KOH is 39.1+16+1=56.1 so you do
which equals to 0.053475 so u 3SF which is 0.0535moles
than u uses the molar ratio which is 3 to 1
so 0.0535÷3=0.0178 which is the moles of FeCl3.
hope this make sense:)
The law of inertia. Basically, every object stays in the same spot unless they are moved by an external force, .
Answer: the balanced equation for the reaction between Mg and O₂ is as follows
2Mg + O₂ --> 2MgO
stoichiometry between Mg and O₂ is 2:1
number of Mg reacted - 4.00 mol
if 2 mol of Mg reacts with 1 mol of O₂
then 4.00 mol of Mg requires - 1/2 x 4.00 = 2.00 mol of O₂
then the mass of O₂ required - 2.00 mol x 32.0 g/mol = 64.0 g
64.0 g of O₂ is required for the reaction
