Answer is <span>
Ni²</span>⁺(aq)
+ 6NH₃(aq)
⇌ [Ni(NH₃)₆]²⁺<span>
</span>
<span>When the concentration of Ni²⁺</span><span>(aq) increases, according to the Le Chatelier’s principle
system tries to become equilibrium by reducing the increased factor. To do
that, the concentration of Ni²⁺</span><span>(aq) should be reduced. Hence, the forward reacted should be
promoted to reduce the Ni²⁺</span><span>(aq) concentration</span>.
Answer:
The Artic Ocean
Explanation:
it is mostly surrounded by land with only a bit of exchange of water with the other oceans
Molar mass :
NH₃ = 17.0 g/mol
(NH₄)₂SO₄ = 132 g/mol
2 NH₃ + H₂SO₄ = (NH₄)₂SO₄
2 x 17 g NH₃ ------------ 132 g <span> (NH</span>₄)₂SO<span>₄
</span>( mass NH₃) ------------ 1.90 x 10⁵ <span> (NH</span>₄)₂SO<span>₄
( mass NH</span>₃) = (1.90 x 10⁵) x 2 x 17 / 132
<span>
( mass NH</span>₃) = 6460000 / 132
<span>
( mass NH</span>₃) = 48939.39 g
<span>
in kg :
48939.39 / 1000 = 48.93 kg = 4.893 x 10</span>¹ kg
<span>
hope this helps!

Answer: the unshared pair of electrons on the nitrogen can accept a proton
Explanation:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
Amines have a general molecular formula of 
which has lone pair of electrons on nitrogen and thus is able to donate electrons to a lewis acid which is short of electrons. In other words nitrogen can accept a proton.
