How many mole of HCL is produced if 4g of hydrogen is completely reacted with chlorine​

Chemistry

Elenna [48]3 years ago
5 0

Answer:

4 moles of HCl are produced.

Explanation:

Given data:

Mass of hydrogen = 4 g

Number of moles of HCl = ?

Solution:

H₂ +  Cl₂   →    2HCl

Number of moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 4 g/2 g/mol

Number of moles = 2 mol

now we will compare the moles of hydrogen and HCl.

                 H₂        :        HCl

                  1          :          2

                  2         :         2/1×2 = 4 mol

Thus, 4 moles of HCl are produced.

kogti [31]

Answer:

Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.

mixas84 [53]

Answer:

1=  K⁺= (Z=19) = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰

2 = Zn²⁺= (Z = 30) =1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰, 3d¹⁰

Explanation:

When an atom lose or gain the electron ions are formed. There are two types of ions cation and anion.

Cation are formed when atom lose the electron.

Anion are formed when an atom gain the electron.

In given question potassium loses its valance electron and form K⁺ cation. Thus its electronic configuration will be written as,

₁₉K⁺ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰

While the electronic configuration of potassium in neutral form is:

₁₉K = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹

The atomic number of zinc is 30 and its electronic configuration is:

₃₀Zn= 1s² 2s² 2p⁶ 3s² 3p⁶ 4s², 3d¹⁰

When zinc atom loses its 2 valance electrons the electron configuration will be,

₃₀Zn²⁺= 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰, 3d¹⁰
