As Fire needs oxygen to burn, Carbon Dioxide Covers the fire like an blanket and cuts the contact of fire to the oxygen present in the air, So Fire stops burning.That is why Carbon Dioxide is Considere as the best Fire Extinguisher.
Answer:
Explanation:
First of all, we need to understand what gravity is. Gravity in its simplest form can be best visualized as a force of attraction, that pulls all objects that have a mass towards itself.
It is usually exerted by an object with a larger mass and felt by objects with smaller masses.
Putting this into context, the earth exerts a gravitational pull on all substances with masses, which are around it. This includes the oceans, birds, airplanes, clouds, and even gasses in the atmosphere. The atmospheric gasses may be light enough to float, but they can't go very far, since gravity is constantly tugging at them. This keeps the gasses that make up our atmosphere, within a reasonable radius, which is very close to the earth. In a nutshell, gravity prevents them from floating away into outer space.
Amino acids combine to form a dipeptide molecule, but their reaction is a condensation reaction.
The exosphere is the uppermost layer of Earth's atmosphere
The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.
<h3> Is Nitrosyl fluoride polar or non polar?</h3>
The affinity for electrons between the two atoms will keep them together, resulting in the sharing of electron density. In the case of Nitryl fluoride, The N-F bond is polar, acting as a dipole with a partial positive charge on the nitrogen atom and a partial negative charge on the fluorine atom, respectively.
<h3>Is Nitrosyl fluoride a gas?</h3>
Nitryl fluoride, NO2F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agent and has been proposed as an oxidiser in rocket propellants (though never flown).
