Answer:
20g of water would freeze at the Same temperature
The carbon atom reduced in the transformation of chloromethane to methyllithium.
The reaction between chloromethane and lithium form methyllithium.
→
In above reaction, methyllithium is formed by the dispersing of lithium metal and adding chloromethane .
The carbon atom in chloromethane is partial positive charge because chlorine is high electronegative atom. The carbon atom in methyllithium is partial negative charge because carbon is more electronegative than lithium.
So, in above reaction two lithium metal donate two electron ( each lithium donate one electron) to the carbon atom(having positive charge) of chloromethane and get negative charge in methyllithium .
The gain of electron is reduction. So,The carbon atom reduced in the transformation of chloromethane to methyllithium.

Answer:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
Explanation:
Sodium hydroxide (NaOH) is a <u>strong base</u> and hydrochloric acid (HCl) is a <u>strong acid</u>. That means that they are totally dissociated into ions in aqueous solution.
When a solution of NaOH is mixed with a solution of HCl, a neutralization reaction occurs, in which a salt (NaCl) and water (H₂O) are formed.
The <em>balanced molecular equation</em> for this reaction is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
