Answer:
It is an example of Exothermic reaction.
Explanation:
It leads to release of HEAT as can be seen water is given in gaseous form.
246800 tons of sulfur dioxide was emitted by the utility company who burned 6.17 million tons of coal.
6.17 million tons of coal contain 2.00% sulfur, hence the weight of sulfur is:
Weight of sulfur = 2% of 6.17 million tons = 0.02 * 6170000 = 123400 tons
123400 tons of sulfur is found in 6.17 million tons of coal
The weight of sulfur dioxide is twice that of sulfur, hence:
Amount of sulfur dioxide emitted = 2 * 123400 tons = 246800 tons
246800 tons of sulfur dioxide was emitted.

Answer:
Δ S = 26.2 J/K
Explanation:
The change in entropy can be calculated from the formula -
Δ S = m Cp ln ( T₂ / T₁ )
Where ,
Δ S = change in entropy
m = mass = 2.00 kg
Cp =specific heat of lead is 130 J / (kg ∙ K) .
T₂ = final temperature 10.0°C + 273 = 283 K
T₁ = initial temperature , 40.0°C + 273 = 313 K
Applying the above formula ,
The change in entropy is calculated as ,
ΔS = m Cp ln ( T₂ / T₁ ) = (2.00 )( 130 ) ln( 283 K / 313 K )
ΔS = 26.2 J/K
