If 10 grams of NaHCO3 react with an excess of HCl, what would be the theoretical mass of NaCl produced?
melamori03 [73]

Answer:

Explanation:Reaction NaHCO3 + HCl ⇒ NaCl + H2O + CO2

Molar mass M = (22.99+1.008+ 12.01+3·16 ) g/mol. Calculate

Amount of substance n =m/M, n(NaCl) is equal.

M(NaCl) = 58.44 g/mol and mass m= n·M

Draw both major organic product(s) that are obtained when 4-chloro-2-methyltoluene is treated with sodium amide followed by trea
victus00 [196]

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).
