Answer 2

1. C2H5OH + K: The reaction between ethyl alcohol (C2H5OH) and potassium (K) is not a typical reaction. Ethyl alcohol is a primary alcohol, and potassium is a highly reactive metal. When these substances come into contact, it is possible for a reaction to occur, but it would not be a simple combination reaction like you might expect.

One possible reaction that could take place is the reduction of potassium ions by ethanol to produce potassium alkoxide and hydrogen gas. This reaction would involve the transfer of electrons from ethanol to potassium. The overall reaction could be represented as:

2 C2H5OH + 2 K → 2 C2H5OK + H2

Please note that this reaction is just one possibility and may not be the most common reaction observed. The reaction outcome can be influenced by various factors such as reaction conditions, concentration, and temperature.

2. CH3OH + HCl: The reaction between methanol (CH3OH) and hydrochloric acid (HCl) is a typical acid-base reaction. Methanol, being a weak acid, can react with hydrochloric acid, which is a strong acid. The reaction can be represented as:

CH3OH + HCl → CH3OH2+ + Cl-

In this reaction, methanol acts as a Bronsted-Lowry base and accepts a proton (H+) from hydrochloric acid, forming a methonium ion (CH3OH2+) and chloride ion (Cl-).

3. C2H5OH + O2: The reaction between ethanol (C2H5OH) and oxygen (O2) represents the combustion of ethanol. When ethanol reacts with oxygen in the presence of a suitable ignition source, it undergoes combustion to produce carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is:

C2H5OH + 3 O2 → 2 CO2 + 3 H2O

In this combustion reaction, ethanol acts as a fuel and undergoes oxidation, while oxygen acts as the oxidizing agent. The reaction releases energy in the form of heat and light.
