For N2(g)+3h2(g) ←→ 2nh3(g) The equilibrium system described by this equation has= 3 reactant molecule(s) and= 2 product gas molecule(s).
Answer:
∴ Q = -7.52kCal
Explanation:
Using the formula for specific heat capacity:
Q = mcΔT
where ΔT = change in temperature (final - initial) = (0 - 100)°C = -100°C
m = mass (g) = 75g
c = specific heat capacity = 4.2 J/g°C in water
⇒ Q = 75 × 4.2 × -100
= -31,500J
But 1J - 0.000239kCal
<u>∴ Q = -7.52kCal</u>

Answer:
A. ocean winds can carry moisture with them and can bring rain and fog over inland areas
Explanation:
It's "A. ocean winds can carry moisture with them and can bring rain and fog over inland areas' for K12 (OHVA to be exact)
Ionic molecules have higher boiling point than covalent molecules.
So that leaves Na2SO4 and NaCl.
The ionic molecule with higher charge will have higher boiling point.
Na2SO4 have ions with charge +-2.
NaCl have ions with charge +-1.
So the answer is C.
