<em>Answer:</em>
There are two major resonance contributors for the en-amine. One contributor have no formal charges, only have one lone pair at N while the other one has positive and negative formal charges.
<em>Explanation:</em>
An en-amine is formed by the condensation reactions of aldehydes or ketone with secondary amine.
The contributor<em> </em>I have no formal charges. It has only one lone pair at Nitrogen atom.
The contributor II has +1 formal charges at N, and -1 formal charges at α Carbon.
Please see attachment. The resonance contributor are given.
Answer:
and can cause changes in motion. Inertia.
Explanation:
Colonialism made African colonies dependent by introducing a mono- cultural economy for the territories. It also dehumanized African labour force and traders. It forced Africans to work in colonial plantations at very low wages and displaced them from their land
Answer: matter and its interaction with energy. Matter has mass and occupies space. A Substance is matter that cannot be separated into other kinds of matter by physical means.
Explanation:
Answer:
c. 2 OH⁻(aq) + 2 H⁺(aq) ⇒ 2 H₂O(l)
Explanation:
Step 1: Write the molecular equation
The molecular equation includes all the molecular species.
H₂A(aq) + 2 NaOH(aq) ⇒ Na₂A(aq) + 2 H₂O(l)
Step 2: Write the complete ionic equation
The complete ionic equation includes all the ions and the molecular species.
2 H⁺(aq) + A²⁻(aq) + 2 Na⁺(aq) + 2 OH⁻(aq) ⇒ 2 Na⁺(aq) + A²⁻(aq) + 2 H₂O(l)
Step 3: Write the net ionic equation
The net ionic equation includes only the ions that participate in the reaction and the molecular species.
2 OH⁻(aq) + 2 H⁺(aq) ⇒ 2 H₂O(l)
