Given the equation representing a reversible reaction:

Chemistry
1 answer:
tester [92]2 years ago
5 0

Answer:

- Acetic acid (CH₃COOH) and hydronium ion (H₃O⁺)

Explanation:

Hello,

In this case, based on the acid-base theory which states that acids are known as H⁺ donors, if we consider the direct reaction:

CH_3COOH(aq) + H_2O \rightarrow CH_3COO^-(aq) + H_3O^+(aq)

It is clear that the acetic acid is the first H⁺ donor as it losses one H⁺ to turn into the acetate ion. Moreover, if we consider the inverse reaction:

CH_3COO^-(aq) + H_3O^+(aq)\rightarrow CH_3COOH(aq) + H_2O

It is also clear that the hydronium ion is the second H⁺ donor as it losses one H⁺ to turn into water.

Best regards.

Give the expected organic product when 3-phenylpropanoic, PhCH2CH2COOH , is treated with NaOH, H20 .If more than one product is
Ann [662]

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

A student performs an experiment to determine the density of an unknown metal. The student obtains the following data...
Vsevolod [243]

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

When you flick a coin so that it slides across a table, it slows down.
Shkiper50 [21]
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
