Question:

Write a balanced chemical equation for each of the following:

  • Solid copper reacts with solid sulfur to form solid copper(I) sulfide
  • Liquid octane reacts with oxygen gas to form carbon dioxide gas and water vapor

Balanced Chemical Equation of Chemical Reactions:

Substances reacting to form a new products is called a chemical reaction. This process, which may occur naturally or man-made, is the basis of all interaction between substances in the atomic and molecular level. A chemical equation is used to represent a chemical reaction. It is composed of chemical formulas of reactants found on the left side and products on the right side of the chemical equation, with an arrow drawn in between to signify a reaction taking place. Chemical equations must be completely balanced to show the exact amount of reactants that form the products. Balancing is performed by inserting coefficients on the elements or compounds. The phase of the substance is represented as a subscript written after the element symbol or compound formula.
