Answer:
Ar 
Explanation:
does not react with anything it has a full electron shell so it does not combine and it is a noble gas
 
        
             
        
        
        
            moles NaOH = c · V = 0.1973 mmol/mL · 29.43 mL = 5.806539 mmol 
            moles H2SO4 = 5.806539 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 2.9032695 mmol 
Hence 
            [H2SO4]= n/V = 2.9032695 mmol / 32.42 mL = 0.08955 M 
The answer to this question is  [H2SO4] = 0.08955 M

Answer:
1) acetylide
2) enol
3) aldehydes
4) tautomers
5) alkynes
6) Hydroboration
7) Keto
8) methyl ketones
Explanation:
Acetylide anions (R-C≡C^-) is a strong nucleophile. Being a strong nucleophile, we can use it to open up an epoxide ring by SN2 mechanism. The attack of the acetylide ion occurs from the backside of the epoxide ring. It must attack at the less substituted side of the epoxide.
Oxomercuration of alkynes and hydroboration of alkynes are similar reactions in that they both yield carbonyl compounds that often exhibit keto-enol tautomerism. 
The equilibrium position may lie towards the Keto form of the compound. Usually, if terminal alkynes are used, the product of the reaction is a methyl ketone.
