It is really self explanitory
Answer:
= - 303.975 Joules
Explanation:
Given that:
The volume of the cylinder = 0.003 m^3
Now, to liters:
The volume = 0.003 *1000 L
= 3 L
For an open cylinder, we mean the atmospheric pressure is at standard condition.
Thus, the workdone = -PΔV
= - 1 atm (3 L)
= - 3 L atm
1 L atm to Joules
= 101.325 Joules
Therefore;
=- 3* 101.325 Joules
= - 303.975 Joules
The balanced reaction that describes the reaction between butane and oxygen to produce carbon dioxide and water is expressed <span>2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g). For 7.36 g of butane, 11. 4 grams of water is produced. When 72.7 grams of CO2 is produced, 23.9 grams of butane is needed.</span>
