When 21.3 moles of c3h8 burn in excess oxygen how many moles of co2 will be formed?

63.9moles

Explanation:

Given parameters:

Number of moles of C₃H₈ = 21.3moles

Unknown parameter:

Number of moles of CO₂ produced = ?

Solution

In order to find the number of moles of carbon dioxide produced we must first write the balanced reaction equation.

This reaction is a combustion of hydrocarbon reaction. It usually occurs in the presence of excess oxygen gas and the product is water and carbon dioxide.

The reaction equation is shown below:

        C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

From the equation:

         1 mole of C₃H₈ produced 3 moles of CO₂

Therefore, 21.3 moles of  C₃H₈ will produce (21.3 x 3)moles of CO₂

The number of mole of carbon dioxide produced is 63.9moles

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
