Find the. Slope of a line with y - intercept of -3 and point (2-1).

answer: no idea buddy

explanation:

Theresa could physically separate the salt from the sand, Solubility separate the substances or separate the substances using melting point separation.

Explanation:

Since both salt and sand are solids, she could get a magnifying glass and tweezers and eventually pick out particles of salt and sand.

One method of separating salt and sand is based on solubility. If a substance is soluble, it means it dissolves in a solvent. Salt (sodium chloride or NaCl) is an ionic compound that is soluble in water. Sand (mostly silicon dioxide) is not.

Another method to separate components of a mixture is based on melting point. The melting point of salt is 1474°F (801°C), while that of sand is 3110°F (1710°C). Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801°C, yet below 1710°C. The molten salt may be poured off, leaving the sand. Usually, this is not the most practical method of separation because both temperatures are very high. While the collected salt would be pure, some liquid salt would contaminate the sand, like trying to separate sand from water by pouring off water.

What will be its effect to earth's crust if this event will continue for millions of years? If this event continues for millions of years, the cracks will become wider and the two land masses will be more far away from each other. The creation of new crust between the land masses also widen.
