Answer:
a. 2257.7 kW b. 6.057kw/K
Explanation:
Steam existing at 100KPa with t = 20C, we can obtain values of enthalpy and entropy from table
h1 = hf = 417.4 kJ/kg
s1 = 1.302 KJ/kg.K
h2 = hg = 2675.1 kJ/kg
s2 = 7.359 kJ/K
a. Electrical Power consumption of system is given by Wel = mass x Change in Enthalpy
Wel = 1 x (h2 - h1) = 1 x (2675.1 - 417.4) = 2257.7 kw
b . Entropy Generation is given by Change in Entropy = Entropy generation - heat dissipated/temperature, since we have a well insulated system with no losses, q =0, hence
ΔS = Sgen + 0/T = Sgen
m(S2 - S1) = Sgen
Sgen = 1 x (7.359 - 1.302) = 6.057 kW/K
Draw the electron-dot (Lewis) structure of O2. You will see that there is a double bond, thus making the chemical bond a covalent bond since they have to share a pair of electrons in order to complete their octet.

When he shot a beam of alpha particles at a sheet of </span>gold foil<span>, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.</span>
Answer:
<u>2</u>H₂S + <u>1</u>O₂ → <u>2</u>H₂O + <u>2</u>S
Explanation:
<u>SOLUTION :-</u>
Balance it by using 'hit & trial' method , and you'll get the answer :-
<u>2</u>H₂S + <u>1</u>O₂ → <u>2</u>H₂O + <u>2</u>S
<u></u>
<u>VERIFICATION :-</u>
<em>In reactant side of equation :-</em>
- Number of atoms in H = 2×2 = 4
- Number of atoms in S = 2×1 = 2
- Number of atoms in O = 1×2 = 2
<em>In product side of equation :-</em>
- Number of atoms in H = 2×2 = 4
- Number of atoms in O = 2×1 = 2
- Number of atoms in S = 2×1 = 2
Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
