In order to determine the number of molecules of nitrogen dioxide that are in 1.28 g of nitrogen dioxide, we first need to know these values:
Molar mass of nitrogen dioxide = 46.0055 g/mol
Avogadro's number = 6.022 x 10^23 molecules/mol
Then, we divide 1.28 g by the molar mass and multiply the resulting value to Avogadro's number:
1.28 g/ 46.0055 g/mol x 6.022 x 10^23 molecules/mol = 1.6755 x 10^22 molecules of nitrogen dioxide
Answer:
The balance equation is 4CH3+7O2=4CO2+6H2O
Explanation:
The given reaction belongs to redox reaction because in this reaction CH3 is getting oxidized to form carbon dioxide(CO2) and oxygen is getting reduced to generate water(H2O).
Both oxidation and reduction will accompany the product.
I have balanced the reaction by equaling the atoms of each element on both sides(reactant side and product side).
Answer:
H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)
Explanation:
Carbonic acid dissociates into water and carbon dioxide which is gas which is used as a fire extinguisher and also which is identified after expose to the flaming and glowing splints. It is a colorless gas which can be identified by brisk effervescence seen in the tube.
<u>The balanced reaction of the decomposition of carbonic acid is:</u>
<u>H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)</u>
FeS known as iron sulphide is formed by the following reaction:
Fe + S ................><span> FeS
</span>
Iron sulphide has a molar mass of 87.910 grams. It has a grey color and can either be in the form of a powder of in the form of lumps.
It is insoluble in water and it reacts with acids.
Its density is 4.84 g/cm^3 and it has a melting point of 1194 degrees celcius.
