Aleksandr-060686 [28]3 years ago
5 0

Answer: “We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering.”

― Carl Saga

The combustion of 1 mol ch4 releases 803 kj of energy. how much energy is produced from the combustion of 5.00 mol ch4.
Annette [7]

Answer : The energy produced from the combustion of 5 mole CH_4 is 4015KJ

Solution : Given,

Released energy = 803 KJ

The balanced combustion reaction is,

CH_4+2O_2\rightarrow CO_2+2H_2O

As per the question,

1 mole of CH_4 releases energy = 803 KJ

5 mole of CH_4 produced energy = \frac{5mole}{1mole}\times 803KJ=4015KJ

Therefore, the energy produced from the combustion of 5 mole CH_4 is 4015KJ

What kind of chemical bonds are represented by the product in the following diagram?
katovenus [111]
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
