Oxidizing and reducing agents are always assigned with reference to the reactants side of a chemical equation, so now all we have to do is use our definitions of oxidizing and reducing agents to finish the problem. In a full sentence, you can also say C2H6 (ethane) reacts with O2 (oxygen) and produce H2O (water) and CO2 (carbon dioxide). To describe chemical reactions for which electrons are transferred (oxidation-reduction reactions). The reducing agent, or reductant, is a species that undergoes oxidiation loses or "donates" electrons (i.e. when a substance loses one or more electrons during a reaction, therefore attaining a higher, more positive oxidation number, ex: many metals reacting with oxygen to make an ionic metal oxide compound. There are 2 Carbons on the left and only 1 Carbon on the right side of the reaction. Step 3: Use the change in oxidation number to identify the oxidizing and reducing agents. ions do not change their charges; they do not follow the pattern of redox reactions. Making educational experiences better for everyone. Explanation: a combustion reaction is an exothermic reaction in which something reacts with oxygen. In cases that these rules do not discuss, the unknown oxidation number of an element can generally be found by assigning all known oxidation numbers in the compound and applying the sum rule to solve for it.

Monochromatic red light is incident on a double slit, and the interference pattern is viewed on a screen some distance away. Likewise, we can determine that O2 (g) is the oxidizing agent since O was reduced. Is the reaction below a redox reaction? To find the mass of O2 in excess, we can use the mol ratio of the balanced equation and dimensional analysis as follows: moles O2 used up: 2 mol C2H6 x 7 mol O2 / 2 mol O2 = 7 moles O2 used up, moles O2 left over = 8 moles initially present - 7 moles used up = 1 mol O2 left over, mass O2 left over = 1 mol O2 x 32 g/mol = 32 g O2 left over. A reducing agent decreases the oxidation state of the reduced substance by making it to gain electrons, while the reducing agent increases its oxidation state by losing the electron.
