CALCULATING HALF LIFE LAB REPORT. I need helping filling out the two tables, making a graph and answering some questions.

The tables have not been filled out yet at all, and I haven't been able to insert the graph because of it, need some help!!

Question : scientist finds a piece of wood that is thought to be from a ancient fire Circle. They find the word that contains the amount of carbon-14 see that is approximately 1/6 of the current atmospheric 14c levels determine approximately how many years ago the tree was chopped down to be used for firewood if he started with 1 million carbon-14 atoms how many atoms of remain in the wood? 14c has a t1/2 of 5, 750 years. ​

If a bottle of olive oil contains 1.4 kg of olive oil, what is the volume, in milliliters ( ml ), of the olive oil?

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
