Answer:
669 Liters
Explanation:
From the equation, it takes 3/2 as much hydrogen as ammonia gas
3/2 * 446 = 669 Liters of H2 gas
Answer:
Gas
Explanation:
This is kind of like the process of evaporating
The current needed to deposit all of the nickel in 5 hours is 2.219 A

What is Faraday's Law of electrolysis?</h3>
According to the first law of Faraday, the amount of substance liberated at an electrode is directly proportional to the quantity of charge passed through an electrolyte.
m = zq , where z = electrochemical equivalent
An electrochemical equivalent is the mass of the substance liberated at an electrode when 1 Columb of charge is passed through the electrolyte.
For the nickel,
z = 2
The molar mass of NiS0₄ = 154.75 g
154.75 g of Ni needs 2 x 96485 C
32 g of Ni needs
32 g of Ni needs 39944.79 C
We know,
q = It
Where q = charge
I = current and t = time in seconds
q = 39944.79 C and t = 5 x 60 x 60 = 18000 s
= 2.219 A
Hence, the current needed to deposit all the nickel is 2.219 A in 5 hours

Answer:
The concept of lewis acids and bases can explain the acidic nature of CO2. A lewis acid is a compound which can accept an electron pair whereas a lewis base is a compound which can donate an electron pair. CO2 acts as a lewis acid.
Answer:
Ionic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons. 2. In an ionic compound, bonding involves a metal and nonmetal, whereas, in the covalent compound, bonding is between nonmetals
