Answer:

See explanation

Explanation:

We separate substances based on their important properties such as reaction to heat, solubility in water, magnetic properties, etc.

To separate sodium chloride and potassium trioxonitrateV, we need to heat the solution. KNO3 dissolves at a high temperature and crystallizes out as the solution is cooled.

Hence when we heat the solution, KNO3 dissolves, as we cool the solution, solid KNO3 crystals are obtained while NaCl remains in solution. We have now separated the two salts in the solution.

Note that the solubility of NaCl is almost independent of temperature.

What are the two different types of ocean currents, and how are they formed?

suter [353]

Answer:

Explanation:

There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences. Density depends on temperature and salinity of the water. Cold and salty water is dense and will sink. Warm and less salty water will float.

a solution of HCI contains 36 percent HCI,by mass and calculate the mole fraction of HCI in the solution?

denis-greek [22]

Explanation:

You have a solution that contains 36 g HCl dissolved in 64 g water

Molar mass HCl = 36.45 g/mol

Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol

Molar mass H2O = 18 g/mol

Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol

Total mol = 0.9875 + 3.5556 = 4.5431 mol

Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174

Mol fraction H2O = 3.5556 / 4.5431 = 0.7826

The answer should have 2 significant digits:

Mol fraction HCl = 0.22

Mol fraction H2O = 0.78

Mol fraction has no units.

There are _____ major plates that make up the most of the continents and the Atlantic and Pacific Ocean.

nasty-shy [4]

Answer and Explanation:

D) 7 is the answer

Together, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.
