Explain where the carbon stored in fossil fuels comes from. <br><br>Thanks!&lt;3
DochEvi [55]

Since organic and inorganic forms contain carbon, it's safe to say that the carbon stored in fossil fuels are from the decomposed plants and animals that made the fossil fuels.

Explanation:

Fossil fuels are made from decomposing plants and animal matters. These fuels are found in the Earth's crust and contain carbon and hydrogen (hydrocarbon).

Carbon is stored in the lithosphere in both inorganic and organic forms. Inorganic deposits of carbon in the lithosphere include fossil fuels.

Examine the equation.
nlexa [21]

The chemical equation after it is balanced  as C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O.

Thus, the correct option is A.

<h3>What is balanced equation?</h3>

Balanced equation is defined as a chemical equation where the left and right sides have the same mass of each element.

The chemical formula of a material included in the reaction equation contains a number known as the reaction coefficient. For balancing reagents and products, the reaction coefficient is helpful.

Variables can be used to balance chemical reactions. How to equalize the reaction equation in steps:

1. assigns a coefficient to each substance in the reaction's equation, such as a, b, or c.

2. Create an equation based on the number of atoms' similarity, where the number of atoms equals the coefficient plus the index of the reactant and the product.

3. Decide on the material whose chemical formula is the most complicated and set its coefficient to 1.

When hydrocarbons and oxygen react to form gas, CO2 and H2O are the byproducts (water vapor). steps are possible

balancing the final O atoms, C, and H

Reaction :

C₃H₈ + O₂ ⇒ CO₂ + H₂O

1. Gives a coefficient

  • C₃H₈ + aO₂ ⇒ bCO₂ + cH₂O.
  • C ⇒ left = 3 and right = b ⇒b = 3
  • H ⇒ left = 8, right = 2c ⇒2c=8 ⇒ c = 4
  • O ⇒ left = 2a, right = 2b+c ⇒ 2a=2b+c⇒2a=2.3+4⇒2a=10⇒a=5

The final chemical equation :

C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O
