The minimum amount of energy needed to start a chemical reaction is known as:
nadya68 [22]

Answer:

The correct option is B. Activation energy

Explanation:

The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.

For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.

The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.

The angle of Earth's tilt has changed throughout Earth's history and is still changing today. If Earth's tilt were to decrease
olganol [36]

Answer:

The world climate would drastically change.

Explanation:

  • First off, both poles would have rapid expansion, with the freezing of more water near the poles.
  • Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
  • Deserts would expand and the average temperature would rise.
  • Also, many animals would also die out, because of the change in their environments.
  • Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.

Function of the plant cell wall?
bekas [8.4K]
<span>The function of a cell wall has the same function of the cell membrane; it protects the cell. Cell wall is made up of cellulose that is only present in plant cells. Cellulose is a sugar that has a sheet like structural carbohydrate. It is rigid that is used for support and provides protection to the plant cell from damage. They cannot be dissolved in water. An example is if you eat food that contains mostly of leaves. You will observe that you will eliminate the same material as when you it. That is because our human body does not have the enzyme that dissolves the cellulose.</span>
