A salt is an ionic compound which needs a positive charge ion and a negative ion charge to form a salt.This means that the pair of element should be a metal and non-metal.This is simply because metal atoms tend to lose negative charge electrons and form positive ions while non-metals tend to receive the electrons from the metal atom to form negative charge ions.So answer is Cl and Li.
When the temperature is colder the oxygen is thicker , when it's warmer the oxygen is thinner
The right answer is The texture.
In petrography, the texture (sometimes called structure) of a rock characterizes the arrangement of the crystals between them at the scale of the sample, the thin slice or even on a finer scale.
Texture is a characteristic determined by the size, shape and disposition of minerals in a rock that is observed at the microscopic scale. It allows to build the relationship between these characteristics and the conditions of formation of a rock (especially in the case of magmatic rocks, the rate of cooling).
