To break a chemical bond, particles need to collide with a certain amount of ____?

Explanation: To break a chemical bond, it is required that particles must have certain amount of energy so that when they can collide with each other due to this energy. Therefore, there will exist a certain amount of force between the particles which will help in breaking the chemical bond. …

Research conducted on what happens when atoms get excited has helped in the identification of the atoms in the universe. What happens when atoms get excited? Atoms change into a particular shape. Atoms lose subatomic particles. Atoms produce a particular odor. Atoms release a particular color of light..

Answered by answersmine AT 22/10/2019 – 02:54 AM I believe the correct answer is the last option. When atoms get excited, atoms would release a particular color of light. When atoms gets excited, the electrons would move from a lower level to a higher level. However, this state is only …

What is the difference between active transport and diffusion in terms of movement of particles?

Answered by answersmine AT 22/10/2019 – 03:14 AM Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient, using energy released during respiration. Post your answer

Select the statement that best describes how the forces relate.A. The object on which they are acting and the distance to that object determines the amount of force.B. nuclear and magnetic forces are different because magnetic forces are associated with unmoving charges, and weak nuclear forces are associated with moving charges.C. All forces are related to the mass of the object on which they are acting.The larger the mass, the weaker the forces become. D. Magnetic and electrical forces are similar because they are both related to the interactions between charged particles.

The gravitational force Fg between two objects is given by the equation: Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies.  Due to the gravitational attraction the pencil and the eraser will …
