Salt and water are mixed together in a bowl. the salt dissolves. the bowl of salty water is left out on the table. after a few days you know this that the water is gone in that the ball is covered in salt what can you conclude?

1) salt in water are an element

2) salt and water are a molecule

3) salt and water are a mixture

4)salt and water are a compound

its either 3 or 4 kid

Explanation:

i dont think i need to say why T^T

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
