Answer:
It is prepared small amounts of hydrogen cloride for uses in the lab.
It can be "generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride."
Answer:
<h3>D energy of motion</h3>
Explanation:
Kinetic energy is the energy present in mass in motion
Answer:
See figure 1
Explanation:
We have to remember that in the isomer structures we have to <u>change the structure</u> but we have to maintain the <u>same formula</u>, in this case
.
In the formula, we have 1 nitrogen atom. Therefore we will have as a main functional group the <u>amine group</u>.
In the amines, we have different types of amines. Depending on the number of carbons bonded to the "N" atom. In the <em>primary amines</em>, we have only 1 C-H. In the <em>secondary amines</em>, we have two C-N bonds and in the <em>tertiary amines</em>, we have three C-N bonds.
With this in mind, we can have:
-) <u>Primary amines:</u>
1) n-butyl amine
2) sec-butyl amine including 2 optical isomers
3) isobutyl amine
4) tert-butyl amine
-) <u>Secondary amines:</u>
5) N-methyl n-propyl amine
6) N-methyl isopropyl amine
7) N, N-diethyl amine
-) <u>Tertiary amines:</u>
8) N-ethyl N, N-dimethyl amine

Answer:
The answer to your question is 0.98 g of H₂
Explanation:
Data
mass of H₂ = ?
mass of Zn = 31.8 g
Balanced chemical reaction
Zn + H₂SO₄ ⇒ ZnSO₄ + H₂
Process
1.- Calculate the molar mass or atomic mass of Zinc and hydrogen
The Atomic mass of zinc = 65 g
The Molar mass of H₂ = 2 g
2.- Use proportions and cross multiplication to find the mass of H₂ formed.
65 g of Zn ----------------- 2 g of H₂
31.8 g of Zn -------------- x
x = (31.8 x 2) / 65
x = 63.6/65
-Result
x = 0.98 g of H₂
