Which factor is most important to consider when evaluating a journal article about global warming? is the article long enough? does the article contain facts or only opinions? did the author of the article use complex, scientific words? does the author of the article have a doctorate degree?

All of these factors are very important and should be considered when evaluating a journal article about global warming we have to take account of length, facts and opinions, scientific words, author degree but the most important of all is the facts and opinions or the content of that journal.

Factors to consider about journals

The most important factor to consider when evaluating a journal is if it contains facts or only opinions.

Explanation:

The quality of a journal article can be determined according to many factors. However, the article has to contain facts in order to be reliable. These articles contain an abstract, bibliography, original research, and conclusions based on the data found. Some can contain opinions but it can not be only those.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
