In which case would recalibrating a thermometer be an important next step in an experiment dealing with boiling points? A) The results of several trials are all very close to each other, but they are noticeably different from the accepted value for the boiling point.

B) A small number of trials are conducted, with results quite different from each other, and with an average that is noticeably different from the accepted value.

C) A single trial is conducted, and the result is very close to the accepted value of the boiling point.

D) The results of several trials vary by a large amount, but the average is close to the accepted value for the boiling point.

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
