You would multiply Al and C12 together.
Answer:
2.94g/L
Explanation:
First, let us derive an expression for the density, using the ideal gas equation:
PV = nRT (1)
V = nRT/ P (2)
Recall:
Number of mole(n) = mass(m)/Molar Mass (M)
n = m/M
Substituting the value of n into equation 2:
V = nRT/ P
V = mRT/ MP
Now Divide both side by m
V/m = RT/ MP
Inverting the above equation, we have:
m/V = MP/RT
But Density = m/V
Density = MP/RT
From the question given, we obtained the following data:
P = 2.3atm
T = 305K
Molar Mass of O2 = 16x2 = 32g/mol
R = 0.082atm.L/K /mol
Density = (32x2.3)/(0.082x305)
Density = 2.94g/L
Answer: D.) non-spontaneous.
Explanation:
A conjugate acid is given by the acid-base theory of Bronsted–Lowry. The conjugate acid of a weak base, trimethylamine is ((CH₃)₃NH⁺) trimethylammonium ion.
<h3>What is a conjugate acid?</h3>
A conjugate acid is a compound that has been formed when a base accepts the hydrogen or the proton ion from an acid. It can also be said that a hydrogen ion is added to a base.
The conjugate acid differs from the base by the addition of one proton ion to it. The reaction of a weak base, trimethylamine can be shown as,
(CH₃)₃N(aq) + H₃O⁺(aq) ⇌ (CH₃)₃NH⁺(aq) + H₂O(l)
Here, the trimethylamine compound has accepted a proton from hydronium to produce a conjugate acid, trimethylammonium cation, (CH₃)₃NH⁺.
Therefore, trimethylammonium (CH₃)₃NH⁺ is the conjugate acid of trimethylamine.
