Calculate the amount of heat needed to boil 183.g of ethanol ( CH3CH2OH ), beginning from a temperature of 33.9°C . Round your a

Shkiper50 [21]

Answer:

19,700 Joules

Explanation:

Quantity of heat (Q) = mc(T2-T1)

m (mass of ethanol) = 183g

c (specific heat capacity of ethanol) = 2.44J/g°C

T2 (boiling temperature of ethanol) = 78°C

T1 (initial temperature of ethanol) = 33.9°C

Q = 183×2.44(78 - 33.9) = 183×2.44×44.1 = 19691.532 = 19,700 Joules (to three significant digits)

How do properties move if in solid

Schach [20]

Answer:

In the solid phase, the forces of attraction have completely overcome molecular motion, and the movement of the particles has been reduced to vibrating in place. The particles cannot move past one another and are held in a tightly-packed pattern, so there is very little space between the particles.

What is the standard potential, e∘celle∘cell, for this galvanic cell? use the given standard reduction potentials in your calcul

Olin [163]

The standard potential for the given galvanic cell is 0.477 V

<h3>What is electrode potential?</h3>

The electrode potential is the electromotive force of a galvanic cell built using a standard reference electrode and another electrode whose potential is to be found.

There are two types of electrode potential

Oxidation potential - The potential associated with oxidation reaction is known as oxidation potential

Reduction potential - The potential associated with reduction reaction is known as reduction potential

At the anode, oxidation occurs

$Sn(s)\rightarrow Sn^{2+}(aq)+2e^-$

At the cathode, reduction occurs

$Cu^{2+}(aq)+2e^-\rightarrow Cu(s)$

$E^o_{cell} =E^o_{cathode} -E^o_{anode}$

= 0.337 - (-0.140)

= 0.477 V

Thus, The standard potential for the given galvanic cell is 0.477 V
