Hydrogen sulfide H2S is produced during decomposition of organic matter. when .5000 mol H2S burns to produce SO2 and H2O. -281.0 kJ of heat is released. what is this heat in kilocalories.
Can you help me start this please
There are 4.184 Joules in 1 calorie.
There are 1000 calories in a kcal and 1000 J in a kJ.
-281.0 kJ ( 1 Joules/ 1000 kJ)(1 calorie/ 4.184 Joules)(1 k cal/ 1000 calories)
is this the correct set up
There are 1000 J in a kJ, NOT 1000 kJ in 1 J as you have it.
Sure, I'd be happy to help! To convert the heat from kilojoules to kilocalories, we can use the conversion factor that there are 4.184 kilojoules in 1 kilocalorie.
So, first, we need to calculate the heat in kilocalories.
Given that -281.0 kJ of heat is released, we can set up the following equation:
-281.0 kJ * (1 kcal / 4.184 kJ) = ? kcal
By multiplying the heat in kilojoules by the conversion factor, we can calculate the equivalent heat in kilocalories.
Plugging the numbers into the equation, we have:
-281.0 kJ * (1 kcal / 4.184 kJ) ≈ -67.18 kcal
Therefore, the heat released during the combustion of 0.5000 mol of H2S is approximately -67.18 kilocalories.

Yes, I can help you with that. To convert the heat released from kJ to kilocalories, we need to use the conversion factor:
1 kilocalorie (kcal) = 4.184 kilojoules (kJ)
Therefore, we can set up a ratio to convert the given heat in kilojoules to kilocalories:
1 kilocalorie / 4.184 kilojoules
Now we can calculate the heat in kilocalories:
Heat in kilocalories = (Heat in kilojoules) * (1 kilocalorie / 4.184 kilojoules)
Do you have the heat in kilojoules?
