A. methane contains tightly held electrons. B. Carbon Dioxide and H2O contain loosely held electrons. C. Bonds with loosely held electrons are converted to bonds with tightly held electrons. D. Polar covalent bonds are converted to non-polar. E. C=O and O-H bonds are converted to C-H bonds. Which one????
When natural gas methane is burned, it undergoes a chemical reaction with oxygen, producing carbon dioxide, water vapor, and heat energy. This exothermic reaction releases energy in the form of heat, which can be harnessed for various applications such as heating homes, generating electricity, or powering vehicles.

Why is methane used for burning in gas fires?
Methane is used for burning in gas fires because it is a highly flammable gas that burns cleanly with a blue flame. It produces a lot of heat energy when burned, making it an efficient fuel source for heating applications. Additionally, methane is readily available and cost-effective, making it a popular choice for gas fireplaces.
Why is the burning of methane is an exothermic reaction?
When methane is burned, it reacts with oxygen to form carbon dioxide and water. This process releases energy in the form of heat and light, making it an exothermic reaction. The formation of the stronger bonds in carbon dioxide and water releases more energy than is required to break the bonds in methane and oxygen.
Is the burning of methane gas in a cooker a physical or chemical change?
The burning of methane gas in a cooker is a chemical change. In this reaction, methane reacts with oxygen to produce carbon dioxide, water, and heat energy. This results in a new substance being formed with different chemical properties than the original methane gas.
How energy is obtained by burning natural gas?
Natural gas is a fossil fuel composed mainly of methane. When it is burned, it is mixed with oxygen to produce heat, water vapor, and carbon dioxide. This process releases energy that can be used for heating, electricity generation, or other industrial applications.
What is burning methane?
Burning methane is a chemical reaction where methane gas (CH4) is combined with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). This reaction releases energy in the form of heat and light, making it a common method for generating heat or electricity. However, burning methane also produces carbon dioxide emissions, contributing to climate change.
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.
Is burning ice a natural resource?
Yes, burning ice, also known as methane hydrate, is a natural resource. It consists of methane gas trapped in ice crystals and is found in marine sediments and permafrost regions. It has the potential to be a future energy source, but its extraction and use can have environmental implications.
How much energy is released by burning methane?
4450 kJ of energy would be released.

Additionally, methane is readily available and cost-effective, making it a popular choice for gas fireplaces.
Which human activities are warming earth's atmosphere?
Human activities that contribute to warming Earth's atmosphere include burning fossil fuels for energy, deforestation, agriculture practices such as methane emissions from livestock, and industrial processes that release greenhouse gases like carbon dioxide and methane into the atmosphere.
Burning which fossil fuel - coal oil and natural gas - contributes least to global warming?
Burning natural gas contributes least to global warming compared to coal and oil. Natural gas produces fewer greenhouse gas emissions, such as carbon dioxide and methane, per unit of energy generated.
Why is the burning of methane is an exothermic reaction?
When methane is burned, it reacts with oxygen to form carbon dioxide and water. This process releases energy in the form of heat and light, making it an exothermic reaction. The formation of the stronger bonds in carbon dioxide and water releases more energy than is required to break the bonds in methane and oxygen.
Does natural gas produce energy all of the time?
Natural gas (or methane) releases energy only when it is burnt.
Does natural gas store chemical energy?
Yes, methane is a fuel, a source of energy.
Is the burning of methane gas in a cooker a physical or chemical change?
The burning of methane gas in a cooker is a chemical change. In this reaction, methane reacts with oxygen to produce carbon dioxide, water, and heat energy. This results in a new substance being formed with different chemical properties than the original methane gas.
