<span>Consider the balanced equation below.
2H2S + 3O2 ---> 2SO2 + 2H2O
Which option gives the correct mole ratios?
H2S:SO2 = 2:2 and O2:H2O = 3:2
H2S:SO2 = 2:3 and O2:H2O = 3:2
H2S:SO2 = 4:4 and O2:H2O = 5:4
H2S:SO2 = 4:6 and O2:H2O = 4:4</span>
is the aswer H2S:SO2=2:2 and O2:H2O=3:2
Whichever one has a negative enthalpy value.
The best answer is A) <span>It shows how the temperature of the substance falls as heat is removed.
The cooling curve shows how the temperature of a substances changes with time, as it is allowed to cool. The substance is first heated until completely liquefied, and then allowed to cool. The flat parts of the curve, where temperature is constant with time, show the periods in which the state of matter of the substance changes. One the substance completely changes it state of matter, namely changes from liquid to solid, its temperature continues to drop.
