C₂H8 is Dimethocain-M. In C₂H₈ two atoms of carbon are present. Combustion of 6.40 mole C₂H₈ produced 12.8 moles of CO₂.
Combustion reaction refers to burning of compound in presence of oxygen. The reaction is accompanied by heat and light. One mole of burned carbon produced one mole of CO₂ gas.
Combustion is a chemical reaction between substances ,usually including oxygen and usually accomplished by the generation of heat and light.
Here we see that in C₂H₈ there are there are two carbons present then 2 moles of CO₂ gas is produced i.e. 2 × 6.40 = 12.8 moles.
Hence, 12.8 moles of CO₂ produced in combustion of 6.40 mole C₂H₈.

The mass of an atom comes from the protons and neutrons that are found in the nucleus. The number of protons is the atomic number of an element. To find the number of neutrons, subtract the atomic number from the mass of an atom. The atomic number is 8 and the atomic mass is 16.

For number one, the reaction is the neutralization of a strong acid and a strong base to yield a salt and water. The strong acid is the HCl and the strong base is NaOH. The salt is NaCl.
For number two, the equation is balanced. Na in the reactant side has one atom and also in the product side. O has only one atom in the product and in the reactant. There are 2H’s in the reactant and in the product side (present in H2O, the 2 in H stands for 2 atoms of H). One atom of Cl is present in the reactant and product side.
For number three, the reactants are NaOH-sodium hydroxide and HCl-hydrogen chloride(hydrochloric acid). The products are NaCl-sodium chloride and H2O-water.
