Answer:
D) Water splashing
Explanation:
Displacement is about moving something from its original place. In A, B, and C nothing is being moved. This makes D the only answer!
Answer:
ΔG = - 31.7kJ/mol
Explanation:
It is possible to find ΔG of a reaction at certain temperature knowing Kc following the equation:
ΔG = ΔG° + RT ln Q
ΔG° = -RT lnKc
ΔG = -RT lnKc + RT ln Q (1)
<em>Where R is gas constant (8.314J/molK), T absolute temperature (350°C + 273.15 = 623.15K) and Q reaction quotient</em>
<em />
For the reaction,
3H₂(g) + N₂(g) ⇄ 2NH₃(g)
Q = [NH₃]² / [H₂]³[N₂]
Where the concentrations of each chemical are:
[NH₃] = 1.0mol / 2.5L = 0.4M
[H₂] = 5.0mol / 2.5L = 2M
[N₂] = 2.5mol / 2.5L = 1M}
Q = [0.4M]² / [2M]³[1M]
Q = 0.02
And replacing in (1):
ΔG = -RT lnKc + RT ln Q
ΔG = -8.314J/molK*623.15K ln 9 + 8.314J/molK*623.15K ln 0.02
ΔG = - 31651J/mol
<h3>ΔG = - 31.7kJ/mol</h3>
Answer:
56.82 Kg
Explanation:
Given data:
1 Kg = 2.20 lbs
Number of kilogram in 125 lbs = ?
Solution:
lbs is used for pound. lb is abbreviation of libra. It is Latin word meaning balance.
Both kilogram and pounds are units of mass. Pound is smaller unit than kilogram.
one Kg = 2.20 lbs
Number of kg in 125 lbs:
125 lbs × 1 Kg/2.20 lbs
125 lbs.Kg/2.20 lbs
56.82 Kg
Answer:
A
Explanation:
They are the first to colonize or previously biodiverse steady state ecosystems that have been disrupted ex: Fire
Answer:
<h2>Letter B</h2>
Explanation:
because density is an INTENSIVE PROPERTY not an EXTENSIVE.
