Answer:
128 g of Li will react with 86.1 g of N₂ to completely consume it.
Solution:
The balance chemical equation is as follow,
<span> 6 Li + N</span>₂ → 2 Li₃<span>N
According to this equation,
28 g (1 mole) N</span>₂ reacts with = 41.64 g (6 moles) of Li
So,
86.1 g of N₂ will react with = X g of Li
Solving for X,
X = (86.1 g × 41.64 g) ÷ 28 g
X = 128 g of Li
In the electrolysis of molten BaI₂, the product forms at the cathode Barium metal (Ba).
First ionic bonds in this salt are separated because of heat:
BaI₂(aq) →
(aq) + I⁻(aq).
Reaction of reduction at cathode(-):
(aq) + 2e⁻ → 2Ba(s)
turns into Ba metal.
Reaction of oxidation at anode(+):
2I⁻(aq) → I₂(g) + 2e⁻.
So I⁻ turns into I₂(g)
The anode is positive and the cathode is negative.
In chemistry, the type of process in which decomposition of a chemical substance occurs due to the flow of electricity through the substance is generally known as the electrolysis process. Usually, the electrolysis process becomes in an arrangement in which one electrode of the cathode and one electrode of the anode are present.
In chemistry and production, electrolysis is a technique that makes use of direct electric present-day (DC) to power an otherwise non-spontaneous chemical response.
Electrolysis is commercially crucial as a degree inside the separation of factors from clearly going on sources including ores the usage of an electrolytic cell.
