The downward pressure on the hg in barometer is <u>the same as</u> the pressure of the atmosphere.
The atmospheric pressure or barometric pressure is the force exerted by the air in the atmosphere on the earth's surface.
The atmospheric pressure is caused by air molecules colliding with the surface. The atmospheric pressure at sea level is about 101 kPa and at the cruising altitude of a passenger plane it is 27 kPa.
The atmospheric pressure decrease as the height of a surface above ground level increases.
<h3>What is a barometer?</h3>
A barometer is a measuring instrument used to measure the atmospheric pressure or weight of the air, which is useful for making weather predictions.

Answer:
In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). ... IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol.

White phosphorus burns spontaneously in chlorine to produce a mixture of two chlorides, phosphorus (ii) chloride and phosphorus(v) chloride and heat is evolved. Phosphorus (iii) chloride is a colorless fuming liquid:
P4 + 6Cl2 = 4PCl3
Phosphorus (v) chloride is an off-white solid
P4 +10Cl2 = 4PCl5
Depends on what compound we’re talking about here
