Answer:

The answer to your question is below

Explanation:

Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.

                    Kind of elements         Difference of electronegativity     Bond

a) MgO         Metal - Nonmetal                3.44 -  1.31 = 2.13                     Ionic

b) SrCl₂        Metal -Nonmetal                  3.16 - 0.95 = 2.21                    Ionic

c) O₃             Nonmetal- Nonmetal          3.44 - 3.44 = 0                      Covalent

d) CH₄O       Nonmetal-Nonmetal           3.44 - 2.55 = 0.89                Covalent

   Carbon, Hydrogen and oxygen are nonmetals

2) Silver coins can conduct electricity.

6. The fusion of 4 H-1 nuclei to produce two positrons and one other nuclei.​
KIM [24]

Explanation:

Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.

vodka [1.7K]

Answer:

The average kinetic energy of a particle is proportional to the temperature in Kelvin.

Explanation:

The kinetic molecular theory states that particles of matter are in constant motion and collide frequently with each other as well as with the walls of the container.

The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.

Therefore, the average kinetic energy of a particle is proportional to the temperature in Kelvin.
