Calcium chloride forms an ionic compound with a
regularly arranged lattice of oppositely charged ions.
The Na+ and Cl- ions are held together by
strong electrostatic forces.
Hope that helps
Minerals physical characteristics are hardness,luster,the way it’s solid and chemical would be the way the color changes and it’s density
The smallest particle is the white blood cells because they are the ones that help you breathe
Burning charcoal is a chemical reaction called combustion
The activation energy is the minimum amount of energy that particles must have in order for them to participate in a chemical reaction. During chemical reactions bonds are broken and formed. Particles must collide with sufficient energy in order for the initial bonds to be broken. The activation energy is that that initial minimum energy that the particles can have in order for the bonds to be broken. Stronger bonds would require more energy to be broken and therefore the activation energy for such would be higher.
