Yes, they react tor form water and the corresponding potassium carboxylate salt.
When carboxylic acid react with metal gives Salt and hydrogen
Yes. Grignard reagents are extremely strong bases that deprotonates the carboxylic acid which then becomes a carboxylate.
Amide on heating.
Due to its high bonding It decomposes to potassium oxide and carbon dioxide gas when heated to the right temperature.
Yes it is, oleic acid (18 carbon Chain carboxylic acid) will react with the Sodium Hydroxide (NaOH) and produce a new metal salt carboxylic acid.
A carboxylic acid and an amine react to form nylon.
Potassium does indeed react vigorously with acid and also conducts heat well.
Potassium will react violently, with acid. The reaction can potentially splatter droplets of acid or pieces of burning potassium.
Yes
A reaction between an acid and a metal oxide to form a salt and water as the only products.
Potassium violently reacts with hydrochloric acid forming the potassium chloride and hydrogen gas.
An alcohol and a carboxylic acid salt (carboxylic acid if protonated at end of reaction).
