Your cousin is preparing a classic volcano for her school's science project using baking soda and vinegar, but she is disappointed that her volcano is not as exciting as the one she saw online. Knowing that you're taking chemistry, she asks for your help. Based on what you learned in experiment 2, which of the following changes is likely to result in the most exciting volcano?A. Combining the reactants in their stoichiometric ratio to ensure maximum production of product.
B. Adding excess vinegar to drive the reaction equilibrium toward products.
C. Using more baking soda, because it is responsible for producing the CO2 gas that erupts from the volcano.
D. Forming the baking soda into a cube so it will react all at once.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
