I WILL GIVE THE BRAINIEST ANSWER TO THE FIRST PERSON TO ANSWER. TIMED QUIZ!!!ANSWER QUICKLY PLEASE.

Plants are responsible for a very important energy transformation, as shown.

At left, a small grey circle is followed by an arrow pointing right to a large grey circle with a small white circle centered in it. The 4 arrows point to a vertical row of 4 images, 1 arrow per image. From top there are a medium sized grey circle with a small white circle centered in it, then a small grey circle, then another small grey circle, then another medium sized grey circle with a small white circle centered in it. Then comes + Energy. At the top of the vertical row of 4 images is the label Nucleus. At the bottom of the vertical row of 4 images is the label Nucleus.

Which energy transformation does the picture best illustrate?

radiant to chemical
nuclear to mechanical
chemical to thermal
mechanical to chemical

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

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?
