How many Na cations are combined with each -2 anion in the compound formulas?

Answers

Answer 1

Answer: In ionic compounds, the number of cations (positively charged ions) and anions (negatively charged ions) that combine in a compound is determined by the charge balance.

For example, sodium (Na) has a charge of +1 because it loses one electron to become stable, while anions like those with a -2 charge gain two electrons to become stable.

To balance the charges, you would need two sodium cations (Na+) to combine with one -2 anion. This ensures that the overall charge of the compound is neutral.

So, in compounds with a -2 anion, you would typically find two sodium cations (Na+) combined with each -2 anion.

CLEAR ALL

Answers

Features which are found in plant cellsonly are the chloroplast, large vacuole and cell wall.

Plants and animal cells consists of the following parts ; Mitochondria, cell membrane, vacuole, cytoplasm and so on.

The vacuole present in animal cells are much smaller than those found in plant Cells. Hence, vacuole in animal cells are called small vacuole

Plant cells also consists of cell wall, chloroplast and a large vacuole. All these are missing in animal cells.

Therefore, Only plant cells have "acellwall,chloroplastsandalargevacuole."

Complete the following Empirical Formula & Molecular Formula problem:2.) A compound containing C and Cl has a molar mass of 284.77 g/mol and an empirical formula of CCl.

Answers

Empirical formula is CCl.

Since the molar mass is provided, it is safe to assume that the empirical formula is not equal to the molecular formula.

We need to get the empirical weight to determine the multiple needed to arrive to the correct molecular formula.

Atom Number in Molecule Atomic Weight Total Mass
C 1 12.0107 12.0107
Cl 1 35.453 35.453
total empirical weight 47.4637

Molecular weight / Empirical Weight
284.77 g/mol / 47.46 g/mol = 6 - the multiple needed to be multiplied with the empirical formula to get the molecular formula.

C has a molecular number of 1 => 1 * 6 = 6 Thus C₆
Cl has a molecular number of 1 => 1 * 6 = 6 Thus Cl₆

Molecular Formula is C₆CL₆

The hole in the ozone layer can lead to increases in skin cancer.
a. True
b. False

Answers

Answer : The correct option is, (a) true

Explanation :

Ozone layer : It is a layer which is present in the stratosphere region. Ozone layer is the layer which absorbs more amount of the ultraviolet rays which is the more harmful rays for us. That means ozone layer protect us from the harmful rays (UV rays). Ultraviolet rays causes the skin cancer. When the ultraviolet rays reaches directly to the earth, it cause many type of diseases.

When the hole in the ozone layer then it can lead to increases in skin cancer.

Hence, the given statement is true.

A. True. The ozone layer is very critical to our health.

In chemistry, there are three commonly encountered theories to explain what acids and bases are and what they do. Name these theories and describe what each one states about acids and bases. Give an example to help describe each of the types. Make sure to explain how these theories differ from each other. (Properties of Acids and Bases)

Answers

Answer: The theories are such that if any chemical produce H+ ion then it is an acid and if the chemical produces OH- ion then it's a base.

How is the number of valence electrons related to the ionization energy of an element?A) low ionization energy correlates to elements with fewer valence electrons
B) elements with higher ionization energy tend to have less valence electrons
C) atoms with nearly full valence electrons shells have lowers ionization energy
D) high ionization energy indicated a low likelihood to gain valence electrons

Answers

The number of valence electrons is related to the ionization energy of an element such that when there is few valence electrons, the ionization energy of an element is lower. The trend on the periodic table follows that the ionization energy fairly increases as the number of valence electron increases. Therefore the correct answer is letter "A."
