what mass of natural gas (ch4) must you burn to emit 271 kj of heat?

What mass of natural gas CH4 must you burn to emit?

The mass of CH4 needed is 5.36 g.

What is produced when CH4 is burned?

When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water.

Does methane produce heat energy?

Methane is a very powerful greenhouse gas. One pound of methane traps 25 times more heat in the atmosphere than a pound of carbon dioxide. Methane is also the main ingredient in natural gas. … The methane is burned to produce heat or generate electricity.

Is methane a compound?

Methane

What is the mass of CH4?

16.04 g/mol

What will the products be when CH4 burns in oxygen gas?

Methane, CH4, burns in oxygen gas to form water and carbon dioxide.

What type of reaction is CH4 O2?

combustion
The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.

Does burning natural gas produce methane?

Methane, the primary component of natural gas, produces about half the emissions of coal when burned, but it’s a much more powerful greenhouse gas when leaked into the atmosphere. Scientists have long struggled to pinpoint just how much methane is being released into the atmosphere.

What is the formula of CH4?

CH₄

What is CH4 in chemistry?

Methane (CH4)

Methane is a colorless, odorless, flammable gas that is the simplest hydrocarbon and is the major constituent of natural gas. … Methane is present in the Earth’s atmosphere at low concentrations and acts as a greenhouse gas.

Which statement is correct about CH4?

Option 2 is correct. CH4 is the chemical formula for methane. It is a symmetrical molecule which shows tetrahedral geometry. It is also an overall non polar molecule.

What type of bonding is CH4?

covalent bonds
Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H).

Why is methane written as CH4?

Methane is a simplest of the saturated hydrocarbons with a chemical formula CH4. It consists of four hydrogen atoms and one carbon atom and is the simplest alkane.

What is the mass of HGO?

What happens when you mix CH4 and O2?

1 molecule of methane in an interaction with 2 molecules of oxygen forms 1 molecule of carbon dioxide and 2 molecules of water. Natural gas is the purest gas for burning, which has a simple composition and does not release harmful chemicals into the air. …

what mass of natural gas (ch4) must you burn to emit 271 kj of heat?

What is the product of burning oxygen?

Regardless of the type of hydrocarbon, combustion with oxygen produces 3 products: carbon dioxide, water and heat, as shown in the general reaction below.

When methane CH4 burns it reacts with oxygen gas to produce carbon dioxide and water the unbalanced equation for this reaction is CH4 g )+ O2 G → CO2 g )+ H2O G?

The unbalanced equation for this reaction is CH4(g)+O2(g) → CO2(g)+H2O(g) This type of reaction is referred to as a complete combustion reaction. Solution: The unbalanced equation for this reaction is CH4(g)+O2(g)→CO2(g)+H2O(g); The balanced equation is CH4(g)+2O2(g)→CO2(g)+2H2O(g);

What type of reaction is this CH4 O2 → CO2 H2O?

combustion reaction
The reaction is named a combustion reaction. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. Burning methane releases only carbon dioxide and water.

Is CH4 a reactant or product?

In this chemical reaction, the reactants are methane (CH4) and oxygen (O2), and the products are carbon dioxide (CO2) and water (H2O).

What proportion of natural gas is methane?

85 to 95 percent
As the natural gas delivered to your home is 85 to 95 percent methane, natural gas leaks are predominantly methane. While methane poses the greatest threat to the climate because of its greenhouse gas potency, natural gas contains other hydrocarbons that can degrade regional air quality and are bad for human health.

How much natural gas is methane?

Natural gas is composed of 70-90% methane, a potent greenhouse gas and major contributor to global warming. The American public perceives “natural gas” much more favorably (76% favorable) than other fossil fuels like oil (51% ) or coal (39%).

How much methane gas is in natural gas?

Commercial natural gas stripped of NGL and sold for heating purposes usually contains 85 to 90 percent methane, with the remainder mainly nitrogen and ethane.

What is the formula of ethene?
