Help me please Cane toads are native to Central and South America and to Mexico. In the 1930s, people brought cane toads to Florida and Australia to consume beetles that cause damage to sugar crops. While the cane toads have been successful at reducing beetle populations, they have also had unforeseen impacts as well, such as being toxic to local predators.

A community in Florida wants to minimize the impact that cane toads have on the local ecosystem. Which of the following should they identify as part of defining the problem?
A.
ways to raise money to support their efforts
B.
the predator populations that eat cane toads
C.
methods that have been used to control cane toads in Australia
D.
solutions that are likely to be effective for controlling the cane toad population

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.

let that person have a turn to speak : )

it is the most commonly accepted one
