Butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.
<h3>How are carboxylic acids converted to amides?</h3>
Carboxylic acids are converted to amides by converting them into into an ammonium salt which then produces an amide on heating.
The ammonium salt is prepared by adding ammonium carbonate to an excess of the acid. The ammonium salt is then heated to give the amide
Therefore, butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.
In conclusion, carboxylic acids are converted to amides in two steps.

My answer -
The scientist that performed the cathode ray experiment leading to the discovery of electrons is<span> the
scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized
after the discovery that electrons are present in the atom. In this
model, the atom is composed mainly of electrons. It was describe as plum
pudding because the electrons are dispersed within the atom.
P.S
Happy to help you have an AWESOME!!! day ^-^

Answer:</h3>
A. 1.4 V
<h3>
Explanation:</h3>
We are given the half reactions;
Ni²⁺(aq) + 2e → Ni(s)
Al(s) → Al³⁺(aq) + 3e
We are required to determine the cell potential of an electrochemical cell with the above half-reactions.
E°cell = E(red) - E(ox)
From the above reaction;
Ni²⁺ underwent reduction(gain of electrons) to form Ni
Al on the other hand underwent oxidation (loss of electrons) to form Al³⁺
The E.m.f of Ni/Ni²⁺ is -0.25 V and that of Al/Al³⁺ is -1.66 V
Therefore;
E°cell = -0.25 V - (-1.66 V)
= -0.250V + 1.66 V
= + 1.41 V
= + 1.4 V
Therefore, the cell potential will be +1.4 V
Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>
