What is the volume of 1.9 moles of chlorine gas (Cl2) at standard temperature and pressure (STP)?

2 answers:

5 0

Considering ideal gas behavior, the volume of 1 mol of gas at STP is 22.4 L; then the volume occupied by 1.9 moles is 1.9mol*22.4L/mol = 42. 6 L.

Answer: 43 L

Answer : The volume of chlorine gas is, 42.56 L

Solution : Given,

Moles of chlorine gas = 1.9 moles

As we know that,

At STP, 1 mole contains 22.4 L volume of gas

As, 1 mole of chlorine gas contains 22.4 L volume of chlorine gas

So, 1.9 moles of chlorine gas contains $22.4\times 1.9=42.56L$ volume of chlorine gas

Therefore, the volume of chlorine gas is, 42.56 L

Calculate the density of carbon dioxide at STP

Artist 52 [7]

Answer:

Density = mass/volume

= 44/22.4

= 1.96 gram/liter

The density of the Carbon Dioxide at S.T.P. (Standard Temperature and Volume) is 1.96 gram/liter.

Determine the maximum number of electrons in the 2f designation

How many electrons fit in each shell around an atom?

The maximum number of electrons that can occupy a specific energy level can be found using the following formula:

Electron Capacity = 2n2

The variable n represents the Principal Quantum Number, the number of the energy level in question.

Energy Level
(Principal Quantum Number) Shell Letter Electron Capacity
1 K 2
2 L 8
3 M 18
4 N 32
5 O 50
6 P 72
Keep in mind that an energy level need not be completely filled before electrons begin to fill the next level. You should always use the Periodic Table of Elements to check an element's electron configuration table if you need to know exactly how many electrons are in each level.

How many total moles of ions are released when the following sample dissolves completely in water? 6.188 x 10 21 formula units o

elixir [45]

Answer:

e. 3.08 x 10⁻² mol of ions.

Explanation:

Every 1.0 mole of any compound contains Avogadro's number of molecules (6.022 x 10²³).

We can get the no. of moles of NiCl₂ using cross multiplication:

1.0 mol NiCl₂ contains → 6.022 x 10²³ molecules.

??? mol NiCl₂ contains → 6.188 x 10²¹ molecules.

∴ The no. of moles of NiCl₂ = (1.0 mol)(6.188 x 10²¹ molecules)/(6.022 x 10²³ molecules) = 1.028 x 10⁻² mol.

NiCl₂ is ionized according to the equation:

NiCl₂ → Ni²⁺ + 2Cl⁻.

Which means that every 1.0 mol of NiCl₂ is ionized to produce 3.0 moles (1.0 mol of Ni²⁺ and 2 moles of Cl⁻).

<em>∴ The total moles of ions are released</em> = 3 x 1.028 x 10⁻² mol = <em>3.083 x 10⁻² mol of ions.</em>

what has 4 valence electrons, shows properties of metals and non metals, and has 32 protons in the nucleus of each atom

12345 [234]

Here is your answer

$\bold{Germanium}$

REASON:

Elements which have 4 valence electrons are generally metalloids.

The metalloids show the properties of both metals and non-metals.

We know that,

no. of protons= Atomic number

So,

Atomic no.= 32

Hence,

The element is Germanium which is a metalloid with 4 valence electrons and has 32 protons in nucleus of each atom because it has atomic no. 32
