1) The drastic decline in the number of Kirkland's warblers, prompting the U. S. Forest Service to include the Kirtland's warbler on the list of endangered species in 1967 under the Endangered Species Preservation
Act of 1966 was
A) eggshell thinning due to DDT use.
B) habitat loss as young Jack pine forests matured,
C) competition for food among the other nortlern bird species,
Eliminate
D) the increase in wildfires that destroyed the developing Jack pine forests.

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

Condensation happens when water vapor cools. true or false? ?

If many scientists conduct the same or similar experiments, and all obtain similar results, a can be written, which is a generally agreed-upon statement that explains and predicts how a natural phenomenon works.
