Answer:
when 3-phenylpropanoic, PhCH₂CH₂COOH , is treated with NaOH, H₂0 it produce sodium salt of 3 - phenylpropanoic acid with water as a major product.
Explanation:
Carboxylic acid when treated with a base like NaOH or KOH gives carboxylate ion because H⁺ from acid reacts with OH⁻ from base gives H₂0 and salt of sodium carboxylate.
The mechanism of the above reaction given below
The density of the metal is 7.11 g/mL.
<h3>What is the density of the metal?</h3>
The term density of the metal is defined as the ratio of the mass to the volume of the metal. The volume of the metal was obtained by the displacement method. The volume of water that was displaced is the volume of the metal.
Hence;
Mass of the metal= 56.188g - 1.429g = 54.759 g
Volume of the metal = 33.6mL - 26mL = 7.70 mL
Density of the metal = 54.759 g/ 7.70 mL
= 7.11 g/mL

Well it depends on the coin and the tables material, a table is a bit too broad, either what i know could be friction force between the table and the coin or air resistance force. not sure about gravity force
Sorry not sure
