HOPE THIS HELPS. IF SO MARK AS BRAINLIEST

Answer 2

The correct coefficients are $2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O$

Explanation:

According to law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of reactants must be equal to the mass of products.

In order to get the same mass on both sides, the number of atoms of each element on product side must be same as the number of atoms of each element on reactant side.Thus the equations are balanced.

$2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O$
