Answer:
Explanation:
Metallocenes are cyclic organometallic compounds with a double pentadienyl structure consisting of a metal atom in between the two structures. In ferrocene, Fe is the metal in between the two pentadienyl structures.
Nitration reaction is the reaction of nitric acid in the presence of sulphuric acid. When metallocenes, (e.g. ferrocene) are being treated with this stong oxidizing agent (nitric acid), oxidation of organometallic compound takes place. When this oxidation occurs, it oxidizes the oxidation state of the Fe metal from +2 to +3 in ferrocene, and it becomes unstable. Then, as a result, the whole metallocene structure gets destroyed.
Answer:
20.91% of the hydrated calcium sulfate salt is water
Explanation:
<u>Step1</u> : Calculate the mass of H2O that evaporated
A hydrated salt has a mass of 1.803g. After heating at 170° C, this means water will evaporate, the mass of the salt is 1.426g
The difference is water that evaporated.
⇒Mass H2O of hydration =1.803 g - 1.426g g = 0.377 g H2O
<u>Step 2</u>: Calculate the % of water in the hydrated calcium sulfate salt
⇒ mass of H2O = 0.377g
⇒ mass of calcium sulfate salt = 1.803g
⇒ % water in the calcium sulfate salt = (0.377 / 1.803) x 100% = 20.91%
20.91% of the hydrated calcium sulfate salt is water
<u>Answer:</u> The new volume will be
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(at constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the new volume will be
2 C4H8O + 11 O2 —> 8 CO2 + 8 H2O
Using the given formula, the density of the material is 2.015 g/mL
<h3>Calculating Density </h3>
From the question, we are to determine the density of the material
From the given formula
Density = Mass / Volume
And from the given information,
Mass = 65.5 g
and volume = 32.5 mL
Putting the parameters into the equation,
Density = 65.5/32.5
Density = 2.015 g/mL
Hence, the density of the material is 2.015 g/mL.
