Question

Write and balance the equation for the complete combustion of acetylene, C2H2. You do not need to include any phase symbols or energy changes.

Answer 1

The only products will be carbon dioxide and water.

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

Answer 2

The answer is:

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

Further Explanation

In chemistry, the equation of a reaction or chemical equation is that the symbolic writing of a reaction. The statement of the reagent is written to the left of the equation and so the statement of the merchandise is written to the proper. The coefficient written to the left of a statement could be a stoichiometric coefficient, which describes the quantity of that substance involved in an exceeding reaction relative to a different substance. The reaction equation was first made by the iatrochemist Jean Beguin in 1615. in an exceeding reaction equation, reagents and products are connected by different symbols. The symbol → is employed for one-way reactions, ⇆ for two-way reactions, and ⇌ equilibrium reactions.

The reaction might be an action that always produces interchange of chemical compounds. The initial compounds or compounds involved within the reaction are called reactants. Chemical reactions are usually characterized by chemical changes and can produce one or more products that typically have different characteristics from reactants. Classically, chemical reactions involve changes involving the movement of electrons within the formation and breaking of chemical bonds, although the final concept of chemical reactions can even be applied to the transformation of elementary particles like in nuclear reactions.

Chemical compounds are pure chemicals that encompass two or several elements that will be lessened into its constituent elements by chemical reactions. as an example, dihydrogen monoxide (water, H2O) could be a compound consisting of two hydrogen atoms for every oxygen atom. Generally, this comparison must be fixed thanks to its physical nature, not a comparison made by humans. Therefore, materials like brass, YBCO superconductors, "aluminum gallium arsenide" semiconductors, or chocolate are considered mixtures or alloys, not compounds. The characteristic of compounds is the presence of chemical formulas. The statement provides a ratio of atoms in an exceeding substance, and therefore the number of atoms in an exceedingly single-molecule (therefore the statement of ethene is C2H4 and not CH2. The statement doesn't specify whether the compound consists of molecules; as an example, binary compound (table salt, NaCl) could be a compound ionic.
