Answer:
a. W = 2.17 x 10 ⁴ J
b. ΔU = - 5.03 x 10⁴ J
c. Q = 2.86 x 10 ⁻³ J
Explanation:
a.
The student work does 2.17 x 10⁴ J
So W = 2.17 x 10 ⁴ J
b.
The internal energy decreases 5.03 x 10⁴ J
ΔU = U₁ - U₂
ΔU = 0 - 5.03 x 10⁴ J = - 5.03 x 10⁴ J
c.
The formula heat can use:
Q = W + ΔU
Q = 2.17 x 10⁴ J + ( - 5.03 x 10⁴ J )
Q = 2.86 x 10 ⁻³ J
Answer:
<h2>1320 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 600 × 2.2
We have the final answer as
<h3>1320 J</h3>
Hope this helps you
Answer:
Explanation:
The equilibrium mechanism for the reversible acid is catalyzed by the isomerization of non conjugated β, γ- unsaturated ketones, like 3-cyclohexanone to their conjugated α, I²- unsaturated isomers.
Oxygen of the Carbonyl group in the ketone is protonated by the acid and this is followed by the abstraction of an α- hydrogen from the protonated 3-cyclo hexanone to yield ethanol
2-cyclo hexanone can be obtained by acid catalyzation of 3-cyclohexanone isomers through the formation of it's "enol".
