What number of cations is present in 1.17g of sodium chloride ?
taurus [48]

Answer:

1.2 × 10^22 atoms.

Explanation:

Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.

Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

Mole = mass/molar mass

Mole = 1.17/58.5

Mole = 0.02moles

Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.

In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+

0.1204 × 10^23 atoms

1.2 × 10^22 atoms of Na+ (cation)

The O2 molecule breaks apart at lower wavelengths than the O3 molecule. What is the main reason for this?
kozerog [31]

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

<h3>What is ozone?</h3>

Ozone is a blue gas composed of three oxygen atoms bonded together.

It occurs naturally high up in the Earth's atmosphere, where it protects the surface from harmful ultraviolet (UV) rays,

UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.

Ozone molecules are tetrahedral so the bond angle is  109 degree the electrons in the double bond occupy more space that the non-bonding electron pair.

Oxygen has a small size that leads to smaller O-O bond length.

A lone pair of electrons on both the oxygen repel each other leading to weakening of O-O bond.

O3 has longer and weaker bonds than O2, whereas SO2 has shorter and stronger bonds than SO.

Molecular oxygen, O2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol.

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

For the reaction below, an analysis of an equilibrium mixture isperformed at a certain temperature.
DerKrebs [107]

Answer:

k = 3.2 x 10¹¹

Explanation:

The equilbrium taking place is:

  • N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)

And the expression for the equilbrium constant <em>k</em> is

  • k = [NCl₃]² / ( [N₂] * [Cl₂]³)

We are given all the required data from the problem, so now we <u>solve for k</u>:

  • k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
  • k = 3.2 x 10¹¹
