Step 5: Measure the Volume of Each Regularly Shaped Ball What is the volume of the golf ball?
cm3
The volume of the water in the graduated cylinder rose
as some of the water was displaced by the golf ball. Find
the volume of the ball using the formula
V = V;-V
where V, is the volume of the ball, V, is the final volume
of the water, and V, is the initial volume of the water.
Record the volume of the ball in Table A of your Student
Guide.

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
