Kinetic Energy – what does it depend on? The an object moves, theit has. The greater the of a moving object, the it has. Kinetic energy depends on both .

Greater the mass

Greater kinetic energy

Velocity

Greater kinetic energy

Mass and velocity

Explanation:

We know that kinetic energy of object

Where m=Mass of object

v=Velocity of object

Kinetic energy is directly proportional to mass and velocity of object.

When mass of object is greater  then the  object  has greater kinetic energy  when the mass of object is small then the object has small kinetic energy.

When the velocity of object is greater  then the  object  has greater kinetic energy  when the velocity  of object is small then the object has small kinetic energy.

The greater the mass of an object moves,the greater the kinetic energy it has.

The greater the velocity of a moving object,the greater kinetic energy it has.

Kinetic energy depends on both mass and velocity of object.

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.
