Answer:
Kelvin
Explanation:
As we know that
Where P is the pressure in atmospheric pressure
T is the temperature in Kelvin
R is the gas constant
V is the volume in liters
Substituting the given values in above equation, we get -
On rearranging, we get
Kelvin
Answer:
Nitromethane, sometimes shortened to just Nitro, is an organic compound with the chemical formula CH
3NO
2. It is the simplest organic nitro compound. It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent. As an intermediate in organic synthesis, it is used widely in the manufacture of pharmaceuticals, pesticides, explosives, fibers, and coatings.[12] Nitromethane is used as a fuel additive in various motorsports and hobbies, e.g. Top Fuel drag racing and miniature internal combustion engines in radio control, control line and free flight model aircraft.
Explanation:
Preparation
Nitromethane is produced industrially by combining propane and nitric acid in the gas phase at 350–450 °C (662–842 °F). This exothermic reaction produces the four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, including the alkoxyl radicals of the type CH3CH2CH2O, which arise via homolysis of the corresponding nitrite ester. These alkoxy radicals are susceptible to C—C fragmentation reactions, which explains the formation of a mixture of products.[12]
Laboratory methods
It can be prepared in other methods that are of instructional value. The reaction of sodium chloroacetate with sodium nitrite in aqueous solution produces this compound:[13]
ClCH2COONa + NaNO2 + H2O → CH3NO2 + NaCl + NaHCO
AS given that we have started with a solid powder on a glass plate which appears to be blackish yellow, on passing magnet the black particles separated.
so the black particles are magentic in nature. however the yellow portion of powder is not magnetic or diamagnetic
so its clear that we are able to separate the black and yellow portions by simple physical methods.
If we are able to separate any two substances by simple physical methods then it means that the powder is a mixture and not a compount
Answer:
Ionic bonds hold atoms together using the electrostatic charge between their positive and negative ions. These ions are formed when electrons are transferred between atoms, the net loss or gain determining if the ion is positive, called a cation, or negative, an anion.
