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:
Answer is BOTH.
Refer below.
Explanation:
Liz and pat are discussing the pulmonary and systemic circulation. Liz says that the purpose of the pulmonary circulation is to transfer carbon dioxide to the lungs. Pat says the purpose is to carry oxygen away from the lungs. BOTH ARE CORRECT.
Answer:
"Thermometer C, because it measures accurately in the ones place."
Explanation:
Thermometer D measures using tens place. Since we are measuring the liquid's temperature at 47 degrees Celsius, the most appropriate thermometer would measure in ones place, not tens place.
Hope this helps! :)
Answer: pH = 1 ; It is very: acidic .
<span>______________________________________
</span>If the H₃O (hydronium) concentration is:
[H₃O]⁺ = 10⁻¹ M , the pH = 1 ; the solution is very acidic.
