Answer : The type of compound created is Ionic compound and the chemical formula is KCl.

Explanation :

Potassium has 1 electron in its valence shell and chlorine has 7 electrons in its valence shell.

The potassium loses 1 valence electron & make a positive charged ion and chlorine picks it up & make a negative charged ion and then they attract to each other.

Potassium and chlorine atom combine to form potassium chloride by the ionic bonding.

An ionic compound is made of a metal and non-metal element. And in this case, potassium is a metal element and chlorine is a non-metal element.

The ionic compound formation is,

$K+Cl\rightarrow KCl$

The Chemical formula is KCl.

How are sublimation in evaporation similar

diamong [38]

Evaporation is when a liquid turns into a gas, while sublimation is when a solid turns into a gas. Both involve absorbing energy to break apart the bonds of the substance. On the other hand, an example of sublimation is dry ice.

The chemical formula H2O represents one molecule of water.

Gennadij [26K]

There is a total of three atoms present in the water (H₂O) molecule.

An atom is the smallest particle of an element that may or may not be capable of independent existence.

<h3>What is a molecule?</h3>

A molecule is the smallest particle of an element or compound that can exist freely.

<h3>What is a subscript?</h3>

Subscripts are the numbers that come below after a symbol. They tell you the number of atoms of an element. If there is no subscript then it is understood that the subscript is 1.

<h3>How to calculate the number of atoms in a molecule?</h3>

For calculating the number of atoms in a molecule, add the subscripts of that molecule, and you will get the total atoms of it.

For example, in molecule C₂H₅O, there are 2 carbon atoms, 5 hydrogen atoms, and 1 oxygen atom.

Add the subscripts

2 + 5 + 1 = 8

Hence, there is a total of 8 atoms in C₂H₅O.

For the H₂O molecule,

2 + 1 = 3

Hence, there is a total of 3 atoms present in one water molecule.

The concentration of hydroxide ions is less than the concentration of hydronium ions for acidic solutions. True False

wolverine [178]

Answer:

True

Explanation:

It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.

1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.

2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.

The values of pH and pOH always obey the following expression:

pH + pOH = 14

Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.

For example, in an acidic medium:

if pH= 3, pOH= 11

In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.
