How many moles of co2 are priloduced when 3.5 moles of c2h2 reacts?

7mol of CO2

Explanation:

The balanced equation for the combustion of acetylene is

Using the equation coefficients, we can find out the number of moles of CO2 produced as follows.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
