Volume = 250 mL in liters : 250 / 1000 => 0.25 L
Molarity = 0.85 M
Number of moles:
n = M x V
n = 0.85 x 0.25
n = 0.21 moles
Choice B
Answer is: there are 216 moles od water.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
n(H₂) = 226 mol.
n(O₂) = 108 mol; limiting reactant.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(O₂).
n(H₂O) = 2 · 108 mol.
n(H₂O) = 216 mol.
n - amount of substance.
Answer: As sea levels rise, coastal communities will lose land and possibly see damages in infrastructure if the levels rise high enough
Answer:
The most common reason for alloying is to increase the strength of a metal. This requires that barriers to slip be distributed uniformly throughout the crystalline grains. On the finest scale, this is done by dissolving alloying agents in the metal matrix (a procedure known as solid solution hardening
