How many nonbonding electron pairs are there in the lewis structure of the peroxide ion, o22−?

There is 6 non - bonding pairs.
Let me show you one easy method to do this.
o22-, oxygen valence electron = 6 here we have two so total 12, and -2 that means we add electrons so it’s all equal to 14 right.
whenever need to find lone pair, subtract the number you get with the lowest multiple of 8.
here we total 14 valence electron right so lowest multiple of 8 would be 8.
so 14 - 8 = 6 and that is our answer.
Let me know if you have Problem with chemistry.

Answer:

The correct answer is that there are 6 pairs of non-binding electrons.

Explanation:

Hello!

Let's solve this!

In the Lewis structure of hydrogen peroxide we have a simple covalent bond between each of the hydrogen with each of the oxygen. To this is added a simple covalent bond between the oxygen. So we will have:

O22-: this means that we have 6 electrons for each of the oxygen, they are two oxygen so there are 12 electrons and there is a -2 so in total there are 14 electrons.

This must be deducted from the used electrons that are 2 + 2 (with the hydrogen) +2 (of the two oxygen): in total there are six electrons.

14-6 = 8

In other words, there are 4 pairs of non-binding electrons in hydrogen peroxide.

As is the peroxide ion, we must add two freer pairs, which are those that bind with the hydrogen.

The correct answer is that there are 6 pairs of non-binding electrons.

If the neutral solution was boiled to dryness, what would be the formula of the resulting salt.
mash [69]

Answer:

Forumula

XOH + HY = XY + H2O

Explanation:

Salt formed from: Salt Solution

Strong acid + Strong base Neutral

Strong acid + Weak base Acidic

Weak acid + Strong base Basic

Neutral solution example

NaCl = Sodium chloride

HCl = H+ and Cl-

NaOH = Na+ and OH-

OH- = Strong Base

H+ = Strong Acid

Sodium chloride, formed from neutralization of HCl by NaOH.

NaOH + HCl = NaCl + H2O

NaCl in water is not acidic or basic, since it's ions cannot hydrolyze.

So formula would be XOH + YH = XY + H2O

What does the arrangement of the periodic table tell scientists
BlackZzzverrR [31]

Answer:

The arrangement of the periodic table leads us to visualize certain trends among the atoms.

Elements are arranged from left to right and top to bottom in order of increasing atomic number.

The vertical columns (groups) of the periodic table are arranged so that all its elements have the same number of valence electrons (outer ring). All elements within a certain group share similar properties.

The rows are called periods. All elements in a row have the same number of electron shells.

An FM radio station broadcasts electromagnetic radiation at a frequency of 103.4 MHz (megahertz; MHz =106s–1). Calculate the w
kap26 [50]

Answer:

Wavelength=2.899\ m

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 2.998\times 10^8\ m/s

Given, Frequency = 103.4 MHz = 103.4\times 10^{6}\ Hz  ( as 1 MHz = 10⁶ Hz)

Thus, Wavelength is:

Wavelength=\frac{c}{Frequency}

Wavelength=\frac{2.998\times 10^8}{103.4\times 10^{6}}\ m

Wavelength=2.899\ m
