How much kinetic energy does a 2kg object have if it is traveling at a velocity of 2m/s?

Chemistry
1 answer:
Kazeer [188]2 years ago
4 0

Answer:

Given, Mass of an object, m = 2kg

velocity, v = 2m/s

We have,

KE = 1/2 m v²

= 1/2 × 2 (2)²

= 1/2 × 8

= 4J

Hence, 4J is the required Kinetic energy.

Answer:

an estimate of the strength of a bond.

Explanation:

The bond order is given as;

1/2(number of bonding electrons - number of anti bonding electrons)

The bond order tells us about the strength of bond. As the bond order increases, so does the strength of the bond because atoms involved in bonding come closer to each other as the bond length decreases.

Hence, bond order is an index of bond strength. Triple bonds are stronger than double bonds which are stronger than single bonds.

slega [8]

Answer:

The two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place

Explanation:

A complex is made up a central metal atom or ion and ligands. Ligands are lewis bases and they possess lone pairs of electrons. A complex is formed when electrons are donated from ligand species to metals.

However, if the ligand has a negative charge at a particular location and we try to put electrons from the metal near the electrons from the ligand, the two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place.

Which topic is commonly used to explain activation energy and how chemical reactions happen?
Drupady [299]

collision theory

Explanation:

Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
