Please help. thank you! Find an interesting chemical reaction. It can be a simple one but please have some facts and info about it. Thank you!

Mercury chemical bond with aluminum, AKA aluminum amalgam

Explanation:

After the protective oxide layer on aluminum is broken, if mercury were to come into contact with it, then the aluminum will bond with the mercury and will create this interesting tower looking thing upwards. You can learn more about this by searching up Aluminium amalgam, where there is plenty of info about it.

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.
