The mass of an atom comes from
the protons and neutrons that are found in the nucleus. The number of protons
is the atomic number of an element. To find the number of neutrons, subtract
the atomic number from the mass of an atom. So, if an element is 76, the number
of protons AND electrons is also 76.
Answer:
I attached the answer as an image. I also drew in the two most acidic hydrogens.
Explanation:
This goes through the 'benzyne' intermediate, meaning it does an E2-looking reaction by expelling a leaving group (chloride) from the adjacent part of the ring using the amide as a strong base. The triple-bonded benzyne has absurd bond angle strain, and is vulnerable to a good nucleophile like an amide ion, and the resultant sp2 anion is then reprotonated by the acid. I didn't draw in the acid-base reaction in step one, or the spectator ion (sodium).
Respiration removes oxygen from the atmosphere, and photosynthesis puts oxygen into the atmosphere.
The answer would be either b or c because they are both correct
Al +3CuCl--->AlCl3+3Cu , its balanced equation
