Asolution consists of a solute and a solvent mixed together. for the solution in model 1 identify and provide the symbol for the a. solute. b. solvent.

a. Solute: blank circles.

b. Solvent: plus symbols.

Explanation:

Hello,

In this case, in order to clarify the statement, the corresponding figure is attached as a picture wherein it is clear that the solute which is sugar is symbolized by blank circles and the solvent which is water by plus symbols.

Now, it is possible to distribute them in such way due to the fact that the permeable membrane allows the movement of the solvent (water) through it in order to regulate the water content into the cell as the lack of water could cause several issues.

Best regards.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
