If its sodium it would have 11 electrons
Answer:
The mole fraction of benzene if 0.43
Explanation:
Let's apply the colligative property of vapor pressure lowering.
P° - Ps = P° . Xm
Where P° is vapor pressure of pure solvent
Ps is vapor pressure of solution
Xm is mole fraction of solute
Determine the solute and the solvent:
Solute: Toluene
Solvent: Benzene (Vapor pressure of pure bencene at 20°C, is 74.7Torr)
74.7 Torr - 32 Torr = 74.7 Torr . Xm
42.7 Torr / 74.7 Torr = 0.57 → Xm
Sum of mole fraction = 1
Mole fraction of bencene + Mole fraction of toluene = 1
Mole fraction of bencene + 0.57 = 1 ⇒ 1 - 0.57 = 0.43
Answer:
There is no air resistance so B
Explanation:
The correct answer is by working in tandem in a symbiotic manner.
Agouti, a tiny rodent, and the Brazil nut tree are interdependent in the Amazon rainforest. The Brazil nut tree drops its ripe pods to the ground, but if it weren't for the agouti's razor-sharp teeth, the pods wouldn't be broken open. The only animal in the forest that has the propensity to separate pods is the agouti. The agouti benefits from eating the Brazil nuts; in exchange, the agoutis bury and conceal the extra nuts; many of these nuts assume the shape of roots and replenish the Brazil nut trees' supplies. Brazil nut trees appear to only bear fruit in undisturbed forests and are vulnerable to deforestation. They rely on other plants in the rainforest, agoutis for seed dissemination, bees for pollination, and other animals to survive. The Brazil nut tree will also vanish if these other species do.
