When an oxygen atom is attached to a carbon atom, the carbon atom becomes more Oxidized.

Explanation:

In chemistry oxidation reduction are defined as,

Oxidation:

Addition of Oxygen

Removal of Hydrogen

Removal of Electrons

Reduction:

Addition of Hydrogen

Removal of Oxygen

Addition of Electrons

Example:

CH₄ + 2 O₂ → CO₂ + 2 H₂O

In above reaction the carbon atom in CH₄ has an oxidation number of -4 as it is bonded to less electronegative atom i.e. Hydrogen while, on product side the oxidation number of Carbon in CO₂ is +4 as it is attached to more electronegative oxygen atom. Hence, the oxidation number has increased from -4 to +4.

Carbon is also oxidized in reference of addition of oxygen and removal of hydrogen as defined above. Therefore, we can say that when an oxygen atom attaches to carbon atom the carbon gets oxidized.

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.

Write 15 uses of a mercury barometer along with its characterestics

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.
