Answer:
Yes work was done because it takes many muscles to blink. I didn't put it in a paragraph bc I already answered this once.
Explanation:
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 - The substance that is produced from a chemical reaction....
REACTANTS
Answer:
V= 10.2L
Explanation:
NB , n= m/M= CV
Molar mass of NaOH= 40gmol-1
15.3/40= 0.0375×V
Simplify
V= 10.2L
PH = -log[H+] therefore lower pHs contain more H+ ions, so Jack's soup contains more free H+. Since pH is a logarithmic scale and Jack's soup has a pH of 2 less than Charlie's, it contains 10^2 = 100 times more H+ ions.
