The total quantity of heat evolved in converting the steam to ice is determined as -12,928.68 J.
<h3>
Heat evolved in converting the steam to ice</h3>
The total heat evolved is calculated as follows;
Q(tot) = Q1(steam to boiling point) + Q2(boiling point to ice) +Q3(freezing to -42 ⁰C)
where;
Q = = mcΔθ
where;
- m is mass, (mass of water = 18 g/mol)
- c is specific heat capacity,
- Δθ is change in temperature
Q(tot) = 2(18)(2.01)(100 - 135) + 2(18)(2.01)(0 - 100) + 2(18)(2.09)(-42 - 0)
Q(tot) = -12,928.68 J
Thus, the total quantity of heat evolved in converting the steam to ice is determined as -12,928.68 J.

Answer:
Oxidation: a type of chemical reaction where one or more electrons are lost.
Oxidation State / Number: a number assigned to an atom describing its degree of oxidation, meaning how many electrons it has gained or lost.
Reduction: a type of chemical reaction where one or more electrons are gained.
Oxidation-Reduction Reaction: a chemical reaction where oxidation and reduction occurs simultaneously
Explanation:
Reduction always occurs at cathode
Oxidation always occurs in anode
These two process occurs in same way independent of nature of cell whether voltaic or electrolytic.
Answer:
= 913.84 mL
Explanation:
Using the combined gas laws
P1V1/T1 = P2V2/T2
At standard temperature and pressure. the pressure is 10 kPa, while the temperature is 273 K.
V1 = 80.0 mL
P1 = 109 kPa
T1 = -12.5 + 273 = 260.5 K
P2 = 10 kPa
V2 = ?
T2 = 273 K
Therefore;
V2 = P1V1T2/P2T1
= (109 kPa × 80 mL × 273 K)/(10 kPa× 260.5 K)
<u>= 913.84 mL</u>
Answer:
Yes
Explanation:
The virtue that tungsten is metal it means that it does conduct electricity. Tungsten does conduct electricity currents quite well, such as when compared to iron and nickel. It is, however, not a good conductor as compared to other metals though it does get the job done.
