Extracting copper from sulfide ores can be performed by roasting the ore in oxygen, with a subsequent reaction of copper(I) oxide with carbon. Simplified chemical equations for these steps are shown. Mathematically combine the two reactions to create an overall balanced equation that contains Cu(s) as the only form of copper as a product. Eliminate like terms from your final equation and use the lowest whole-number coefficients possible. Which of the following statements is true about the final equation? 2Cu2S+3O2---->2Cu2O+2SO2 CuO+C---->2Cu+CO One mole of CO gas is produced in the overall balanced equation. Cu2O is both a reactant and product in the final balanced equation. There are three reactants and three products in the overall balanced equation. The balanced reaction requires six moles of oxygen gas. Two moles of copper result when two moles of carbon react.

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates). 

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
