What happens if a positively charged rod is brought near a neutrally charged balloon?

A. Nothing will happen until the two objects touch.
B. Electrons in the balloon move closer to the rod.
C. Electrons in the rod move closer to the balloon.
D. Protons in the balloon move closer to the rod.

Explanation:

Electrons are negatively charged particles that surround the nucleus of an atom (when they are not flowing).

Protons are positvely charged particles in the nucleus of the atoms.

Since electrons are the most external particles they are more easily removed and can flow. Protons do not.

A positively charged rod has defficieny of electrons: less electrons than protons.

When a positively charged rod is brought near the surface of a neutrally charged ballon, the positive charge will attract the electrons on the surface of the ballon and will cause them to move closer to the rod. This phenomenun is named charge induction.

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.

i'm pretty sure it is letter c.) car
