16 A doctor says that drinking two glasses of milk in the morning will give students more energy.
Which of the following would be good scientific
evidence for or against the doctor's claim?
a brochure from the doctor stating the
benefits of milk
G data from scientific investigations about
drinking milk in the morning
a TV advertisement that drinking milk in
the morning gives people plenty of energy
statements from five people about how
drinking milk in the morning gives them
energy

mark me the branliest.

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
