Why is the burning of methane is an exothermic reaction?
Exothermic is a release of heat, so when methane burns, it must release heat to be exothermic.
How is the element methane important to human life?
Methane is a chemical compound (CH4), not a chemical element; methane is important as fuel or as feedstock for the chemical industry.
Can people breathe methane?
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.
How much pollution does methane produce?
According to the US Environmental Protection Agency, over 60% of methane emissions come from human activities. The remaining 40% is emitted from other sources such as wetlands, where bacteria decomposes organic materials in anaerobic conditions (oxygen free). Other sources of methane release include termites, oceans, sediments, volcanoes, and wildfires. Carbon dioxide is the main contributor to greenhouse gases, and makes up about two thirds of greenhouse gases produced by human activities. However, weight for weight the contribution of methane to greenhouse gases is comparatively 21 times greater than carbon dioxide over a 100 year period. So although methane 'pollution' is relatively low it is amongst the worst of greenhouse gases.
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
What does the sun release in 1 second that is more than human have released in all history?
methane
Why is methane known as marsh gas?
Because marshes tend to release methane.
What are human emissions?
CO2 and methane from our bodies.
Why is the burning of methane is an exothermic reaction?
Exothermic is a release of heat, so when methane burns, it must release heat to be exothermic.
Is it true that most of the air's pollution is created by fossil fuels?
Yes, but it is also caused by the release of methane gas into the air by human actions such as farting
How is the element methane important to human life?
Methane is a chemical compound (CH4), not a chemical element; methane is important as fuel or as feedstock for the chemical industry.
What is a fart made up from?
A fart is only the release of gases produced during the digestion process.
Can people breathe methane?
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.

Does passing gas pollute the air?
Yes it does because the gasses in the passing of gas can pollute the air but not that much. Some people think that pollution just happens from machines but it can by natural causes too. Human methane production is not significant. Cows produce much more methane gas than humans do. This is a concern because methane is a much more potent greenhouse gas than CO2. Methane from cattle tends to come from belches (cows have multiple stomachs) than from cow flatulence (gas passing).
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
Why is the reaction between methane and oxygen exothermic?
Burning release heat, the molecular structure of methane is destroyed and the bonding energy is released.
