Water is a great solvent. For example, it causes ionic compounds like sodium chloride (table salt) to dissociate. One of these r

easons that water does is because it is polar molecule. Why would water being a polar molecule allow it to break sodium chloride into ions of sodium and chlorine through dissociation?​

Answer:

If you stir table salt into water, the crystal lattice of NaCl will begin to dissociate into Na+ and Cl- ions. (Dissociation is just a name for the process in which a compound or molecule breaks apart to form ions.) Water molecules form hydration shells around the ions: positively charged Na+ ions are surrounded by partial negative charges from the oxygen ends of the water molecules, while negatively charged Cl- ions are surrounded by partial positive charges from the hydrogen ends. As the process continues, all of the ions in the table salt crystals are surrounded by hydration shells and dispersed in solution.  So since water is more positive on one end and more negative on the other end compounds like NaCl start to dissolve because one of them is attracted to the partial positive side of the water and the other is attracted to the partial negative side. Then this process continues until the water kind of coats each of the atoms.

Answer:

A polar molecule has both a partial positive and a partial negative. Since NaCl (sodium chloride) is made out of Na+ and Cl- ions, the positive and negative parts of the water will pull on these ions individually since positive attracts negative and negative attracts positive. This magnetic force causes the Na+ and the Cl- ions to be pulled apart.

The latent heat of melting is 80 calories for 1 gram of ice. if 1 gram of ice absorbs 60 calories what do i get?
Eva8 [605]
Latent heat of melting is the energy that a solid absorbs to change its phase as its liquid. During this process, since all energy is used to change the phase, the temperature is constant.

Here the latent energy of melting for 1 g of ice is 80 calories and that 1 g of ice only absorbed 60 calories. hence the phase is not changed because it requires more 20 calories to melt.

Hence 1 g of ice remains as its solid phase (ice).

Which type of galaxy forms when two other galaxies crash into each other? They are small galaxies made up of bright, young stars
GenaCL600 [577]

Answer:

elliptical galaxy

Explanation

:The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear. The merger of gasses creates new stars, and the new shape becomes more elliptical, globular, or sometimes irregular.
