El gas natural que obtenemos de la hornallas esta compuesto principalmente por propano a-¿cual es el combustible de la reaccion?
b-¿de donde se obtiene el oxigeno que reacciona?
c-¿por que debemos encender un fosforo para que la reaccion ocurra?
d-si las naftas estan compuestas por hidrocarburos¿por que cuando cargamos nafta en las estaciones de servicio, estas no reaccionan con el oxigeno del aire mediante la combustion y se prenden fuego?​

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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

ugh fiel iente of insistí is did kiwis jaj

i think its 100.

hope this !
