This one is a bit long but i am desperate! use the equation below to answer the following questions. ba + znso4 baso4 + zn a. determine the oxidation state of the atoms in the equation reactants and products: oxidation state of ba in reactant: in product: oxidation state of zn in reactant: in product: oxidation state of s in reactant: in product: oxidation state of o in reactant: in product: explain why this is a redox reaction. b. write the half-reactions for the reaction. label the oxidation reaction and the reduction reaction. c. in this equation, what was oxidized and what was reduced? d. in this equation, what is the oxidizing agent and what is the reducing agent?

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
