The bond between K⁺ and Cl⁻ ions is <u>an ionic bond </u>

<h3>Further explanation </h3>

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by forming shared ions or electron pairs

Atoms with high ionization energy and atoms that are difficult to draw electrons will form bonds with shared electron pairs (electrons can be from one atom or two atoms attached)

Inform ions, atoms will release or attract electrons

Ion bonds occur because atoms that have low ionization energy (easily release electrons) form a + ion, and these electrons are bound by atoms that have large affinity energy (easily pulling electrons)

Generally, ionic bonds occur in metals and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity

In Atoms, to achieve stability, K will release one electron so that it has an electron configuration like noble gas Ar

Electron configuration of K (atomic number 19) and Ar (atomic number 18)

K: 2 8 8 1

Ar: 2 8 8

so that it becomes a K⁺ ion

While the Cl atom will bind one electron, so it has an electron configuration like noble gas Ar

Cl: 2 8 7

Ar: 2 8 8

So that it becomes a Cl⁻ ion

Finally, there will be an attractive attraction between positive and negative ions and KCl is formed

So the bond between K + and Action is an ionic bond

Basically since potassium chloride is an ionic compound as it consists of a metal and a nonmetal, the potassium atom will donate one of its valence electrons to chlorine that will accept it and as a result produce oppositely charged ions, where the K + ion and the Cl - ion will attract forming an ionic bond. The compound that results is potassium chloride.

List four physical properties of toothpaste

ra1l [238]

Abrasiveness is the most common property found in almost every toothpaste. The abrasiveness of a toothpaste is responsible for whitening action and removal of debris stuck on tooth enamel. The same abrasiveness can worsen the teeth sensitivity by damaging the tooth enamel. Relative Dentin Abrasivity (RDA) is used to measure a toothpaste’s abrasiveness.

Other physical properties considered in a toothpaste are as follows:

· Presence of fluoride

· pH

· Foaming ability

Fluoride is a key ingredient that delivers strength to the tooth enamel and fights to prevent tooth decay and gum diseases. Salt and sodium bicarbonate are some materials commonly found in a regular toothpaste. Make sure that your toothpaste contains a good amount of fluoride content. You can use any toothpaste but ensure that you have an effective toothbrush that can provide optimum oral hygiene.

Mass of moist aggregate sample as brought to the laboratory: 5,306 grams Mass of oven dried aggregate: 5,229 grams Mass of aggre

Lerok [7]

Answer:

a. 2.748

b. 68.91

c. 1.45%

d. 37.84%

Explanation:

To determine the:

a. The aggregate's bulk Saturated Surface Dry specific gravity

Given:

The mass of the moist aggregate sample is 5,229 g.

The mass of the oven-dried aggregate is 5,306 g.

The mass of the aggregate submerged in water is 5,229 g.

The mass of the Saturated Surface Dry aggregate is 3,298 g.

The aggregate's bulk SSD specific gravity =the dry weight ÷ ( the SSD weight - the submerged weight)

Given:

The mass of the oven-dried aggregate is 5,306 g.

The mass of the Saturated Surface Dry aggregate is 3,298 g.

The mass of the aggregate submerged in water is 5,229 g.

= 5,306 ÷ ( 3,298 - 5,229)

= 5,306 ÷ 1,931 = 2.748

b. The aggregate appearance specific gravity

the aggregate apparent specific gravity = the dry weight ÷ (the dry weight - the submerged weight)

Given:

The mass of the oven-dried aggregate is 5,306 g.

The mass of the aggregate submerged in water is 5,229 g

The aggregate apparent specific gravity = 5,306 ÷ (5,306 - 5,229)

The aggregate apparent specific gravity = 68.91

c. The moist content of stockpile aggregate

The moisture content of stockpile aggregate = ( the moist aggregate weight - the dry weight) ÷ the dry weight

Given:

The mass of the moist aggregate sample is 5,229 g.

The mass of the oven-dried aggregate is 5,306 g

The moisture content of stockpile aggregate = (5,229 - 5,306) ÷ 5,306

The moisture content of stockpile aggregate = 0.0147 x 100% (when expressed in percentage) = 1.45%

d. Absorption

Absorption = (mass of the Saturated Surface Dry aggregate - mass of the oven-dried aggregate) ÷ mass of the oven-dried aggregate x 100%

Given:

The mass of the Saturated Surface Dry aggregate is 3,298 g

The mass of the oven-dried aggregate is 5,306 g.

Absorption = (3,298 - 5,306) ÷ 5,306 x 100% = 37.84%

Question 22 3 p Use Bowen's Reaction Series to describe how different igneous rocks form from a single body of magma. Which spec

Leokris [45]

Answer:

The Bowen's reaction series describes how minerals form in sequential order, forming at higher temperature to a lower temperature. There are two branches of crystallization, one is the continuous branch that is on the right and the other is the discontinuous branch that is on the left.

The minerals that are at the top of the Bowen's reaction series forms at a higher temperature.

In the discontinuous branch, the first mineral to crystallize from the melt is Olivine that forms at a higher temperature of about 1400°C. After crystallization, some melt remains and undergoes fractional crystallization leading to the formation of Pyroxene. Again, with the remaining melt, it reacts and forms Amphibole, followed by Biotite (mica).

In the continuous branch, the first minerals to form are the calcium-rich minerals and successively forms sodium-rich minerals. These minerals that form at a higher temperature are basic in nature and gradually change into acidic minerals.

From both the branches, it commonly forms the mineral Potassium feldspar. After this, the remaining melt combines with the magma and forms Muscovite (Mica), and at a temperature of about 650°C, it forms a more resistant and stable mineral known as the Quartz.
