The diagram describes the distribution or circulation of winds. They go from sites of high pressure (H) to sites of low pressure (L).

The terms cold and warm front refers to winds fronts of low or high temperature. When a cold front reaches a warm one, resulting in an occlusion (occluted front).

A strong wind front can be acompanied by clouds (strong winds very cloudy) or not (strong winds cloudless).

A beaker containing 6.32 moles of PBr3, contains___

NISA [10]

Answer:

3.8 x 10²⁴molecules

Explanation:

Given parameters:

Number of moles = 6.32moles

Unknown:

Number of molecules = ?

Solution:

The number of moles can be used to derive the number of molecules found within a substance.

Now,

1 mole of substance contains 6.02 x 10²³ molecules

6.32 mole of PBr₃ will contain 6.32 x 6.02 x 10²³ = 3.8 x 10²⁴molecules

When 20 grams of KCIO3, is dissolved in 100 grams of water, the solution can be

tia_tia [17]

Answer:

b. unsaturated .

Explanation:

Hello there!

In this case, according to the given information, it turns out necessary for us to bear to mind the definition of each type of solution:

- Supersaturated solution: comprises a large amount of solute at a temperature at which it will be able to crystalize upon standing.

- Unsaturated solution: is a solution in which a solvent is able to dissolve any more solute at a given temperature.

- Saturated solution can be defined as a solution in which a solvent is not capable of dissolving any more solute at a given temperature.

In such a way, since 20 grams of the solute are less than the solubility, we infer this is b. unsaturated, as 33.3 grams of solute can be further added to the 100 grams of water.

Regards!
