Window cleaner is ammonia dissolved in water. This is an example of a _______.
The stoichiometry of the reaction is 5 mols of O2 produces 4 mols of CO2.
1 mol at STP is equivalent to 22.4 liters.
So, 5*22.4 liters of O2 produces 4*22.44 liters of CO2
Then 60 liters of O2 produces 60*4/5 = 48 liters of CO2
Answer:
179Kj/mol
Explanation:
The equation for the reaction is:
CaO + 3C ⇒ CaC₂ + CO
₂
The formula for calculating the heat absorbed is:
∆Hf (Products) - ∆Hf (Reactants)
Using the heat of formation (∆Hf) for each component in the reaction
∆Hf Cao = -635kj/mol
∆Hf C = 0kj/mol
∆Hf CaC2 = -63kj/mol
∆Hf CO2 = -393.5
The heat absorbed = ( -63 + -393.5) – (-635)
= - 456 + 635
= 179kj/mol
Answer:
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
