Answer: Combustion
Explanation:
Methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. Therefore there are four products, carbon dioxide, water, carbon, and carbon monoxide.
Answer:
The Answer is eight.
Explanation:
Sorry if it's too late and it doesn't help! But I hope you have a magnificent day! :3
Explanation:
It is given that the energy change is -162 kJ and work done is -194 kJ. As we know that formula for change in enthalpy is as follows.
dH = dE + W
where, dH = change in enthalpy
dE = change in energy
W = work done
Therefore, the change in enthalpy will be as follows.
dH = dE + W
= -162 kJ + (-194 kJ)
= -356 kJ
As the negative sign indicates heat is being released. Therefore, the reaction is exothermic in nature.
Thus, we can conclude that the change in energy of the gas mixture during the reaction is -356 kJ.
