One day on her walk home from school, Leann noticed some rust on an old car Leann knows that when iron and oxygen chemically react, they can form rust She remembered that models can be used to summarize what happens in a chemical reaction. She decides to create a model of this
chemical reaction What is the name that describes the iron and oxygen found on the left side of Leann's model?
4 Fe + 302 -
• 2Fezos
A products
reactants
C. Scientific notation
D. Synthesis

Explanation:

The reaction model is given as shown below:

                            4Fe   +   3O₂   →   2Fe₂O₃

The name that describes the iron and oxygen found on the left hand side of Leann's model is reactants.

Reactants in a chemical expression are the species that are combining together to give a product.

Some reactions only have one reactant and such a chemical process is often termed decomposition reaction.

The two moles of Fe₂O₃ is the product of the reaction.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
