Answer:bro u already have an answer why are you asking?
Explanation:
Answer: E=∆H*n= -40.6kj
Explanation:
V(CO) =15L=0.015M³
P=11200Pa
T=85C=358.15K
PV=nRT
n=(112000×0.015)/(8.314×358.15)
n(Co)= 0.564mol
V(Co)= 18.5L = 0.0185m³
P=744torr=98191.84Pa
T= 75C = 388.15k
PV=nRT
n= (99191.84×0.0185)/(8.314×348.15)
n(H2) = 0.634mol
n(CH30H) =1/2n(H2)=1/2×0.634mol
=0.317mol
∆H =∆Hf{CH3OH}-∆Hf(Co)
∆H=-238.6-(-110.5)
∆H = 128.1kj
E=∆H×n=-40.6kj.
1) D. An element
2) D. Suspension
3) A. Iodine
4) A. Atoms of the same element
Are there choices we should be choosing from? Or do you just want an explanation?
It is true that methane, which is a greenhouse gas and contributes to global warming.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
Global warming is rise in the average temperature of the Earth's climate system.
Most often greenhouse gases are carbon dioxide (CO2) and methane (molecular formula CH4). These gases come from burning multiple substances: coal, petroleum, plastic and natural gas.
Balanced chemical reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂O
Greenhouse gases are so difficult to measure, because carbone dioxide, methane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.
