17. acetylene gas (c2h2) burns in the oxyacetylene torch for welding. balance the chemical reaction by placing the proper coefficients in front of each reactant and each product. a. what is the coefficient on line (a)? b. what is the coefficient on line (b)? c. what is the coefficient on line (c)? d. what is the coefficient on line (c)?

Explanation:

Acetylene is an organic compound consisting of only carbon and hydrogen atoms, also known as a pure hydrocarbon.

Every hydrocarbon might undergo either an incomplete or a complete combustion. In an incomplete combustion, carbon monoxide is produced along with water, while in a complete combustion, there's enough oxygen to oxidize the resultant carbon monoxide to carbon dioxide.

In a complete combustion of acetylene, it reacts with oxygen to produce carbon dioxide and water:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
