Electrovalent or ionic bonding
The Rutherford model was called the nuclear model because he decided on the atom to consist of both the nucleus, and the orbits of electrons, so he separated the nucleus from being combined with the whole atom
Answer:
Explanation:
For this problem, you will have to convert moles to atoms. Use Avogadro's number.
Answer:
As moedas ficam sujas devido ao oxigênio do ar reagindo com o metal para formar óxido de cobre. Eles se tornam mais escuros à medida que envelhecem, à medida que a camada de óxido aumenta. O vinagre é um ácido (ácido acético) que pode ser usado para limpar superfícies e remover os óxidos indesejados.
Explanation:
Answer:The tendency toward randomness drives the solution process. & The new solvent-solute intermolecular attractions must about the same as the solvent-solvent and solute-solute attractions.
Explanation:
Increase in entropy is a major driving force in chemistry. The dissolution of particles in solvent increases the entropy of the solution hence is a driving force and an important factor that influences solubility. Secondly, the degree of solute-solvent interaction must be approximately the same as that of solute-solute and solvent-solvent interaction since like dissolves like and dissolution of a solute in a solvent depends on intermolecular interaction between solute and solvent.
