What types of elements are shown in the polyatomic ions in model 1?

Answers

We can see here that the elements that are shown in the polyatomic ions in Model 1 are non-metals.

Polyatomic ions are charged chemical species (ions) composed of two or more atoms covalently bonded together. These ions have an overall electric charge, which is the result of gaining or losing electrons to achieve a stable electron configuration. Unlike monatomic ions, which are single atoms with a charge, polyatomic ions are molecular entities.

These ions play a crucial role in chemical reactions and ionic compounds. When polyatomic ions combine with metal or nonmetal ions, they form ionic compounds with distinctive properties. It's important for students of chemistry to learn and understand the common polyatomic ions and their charges, as they are fundamental to various chemical processes and reactions.

I will show you with detailed work for NaCl, but follow the same procedure for the rest of the compounds.

Molar Mass - Find the molar mass of the Na and the Cl and add them together
Na - 23
Cl - 35.5
Add those numbers together 23 + 35.5 = 58.5 g/mol

Moles in 1 tsp:
The mass measured in 1tsp of NaCl was 18 g.  To calculate the amount of moles you take the mass measured and divide it by the molecular weight.
18/58.5 = 0.3077 mol

Moles of each element:
To find the moles each element in the compound you multiply the moles of 1 tsp by the number of atoms of the element in the compound
Na - 1 in NaCl
Cl - 1 in Na Cl
so take 0.3077 * 1 = 0.3077 moles Na (and Cl in this case)

Atoms of each:
take the number of moles calculated and multiply that by Avogadro's number(6.023x10^23) for the number of molecules
So for both Na and Cl:
0.3077 * 6.023x10^23 = 1.853x10^23 atoms for both Na and Cl

Answers

An object will be floating in water if the density is lower and will be sink if the density is higher. Water density would be 1000g/liter or 1g/ml. To determine whether the object float or sink you need to calculate both object density.

The density of object A would be: 2g/ 0.5liter= 4g/liter
The density of object B would be: 3g/ 5liter= 0.6g/liter

It is clear that the object is much lighter than water so both objects would float.

Final answer:

A chemical reaction involves breaking chemical bonds in reactants and forming new bonds in products, which leads to a change in energy and results in new substances with different properties.

Explanation:

During a chemical reaction, there are significant changes in the way atoms are bonded together. The changes can be described in terms of the breaking and forming of chemical bonds and the transfer or sharing of electrons among atoms. Atoms are held together in substances by chemical bonds. During a chemical reaction, these bonds are broken, which leads to the separation of atoms. They subsequently rearrange themselves and form new bonds, resulting in new substances with different properties. The substances we start with are known as the reactants, and the new substances formed are the products. An arrow in the chemical equation represents the direction from reactants to products, which signifies the progression of the chemical reaction. During this process, changes in the energy of the system often occur because breaking old bonds and forming new ones involve either absorption or release of energy.

Answers

Calcium, a group 2 element, naturally loses two electrons in order to become electronically stable. PO43- naturally gains 3 electrons to become more electronically stable. In order to bond with electroneutrality, it is necessary for the ions to bond to create a molecule with 3 Ca2+ ions and 2 PO43- ions, since 3 Calcium ions have a charge of 6+ and 2 phosphate ions have a net charge of 6-. This creates a molecular net charge of 0.

How does the modern periodic table arrange elements?

Answers

Answer:

The periodic table of the elements is ordered in increasing order of the atomic number of the elements (this is their number of protons) and according to the similarity of their properties.

Explanation:

To classify the similarity in the properties, the elements are arranged in 7 rows, periodic calls, and in 18 columns, called groups.  

The chemical elements are ordered according to their properties from left to right and from top to bottom.

In the same group, all elements have the same number of electrons in their last layer. This makes the chemical properties of the elements very similar.

The period that an element occupies coincides with its last electronic layer. That is, an element with five electronic layers will be in the fifth period. This generates that the elements that are in the same row have different properties but similar masses.

The table is also divided into four groups, according to the orbital that the outermost electrons are occupying, and these groups are named according to the letter of the orbital referred to.

In summary, due to this classification by similarity in their characteristics, the elements are divided into three broad categories: metals, metalloids and nonmetals, which at the same time are divided into subgroups.

How does changing electronegativity affect bond character?

Answers

When it comes to Chemical bonds, it stretch out along a range between two theoretical limits, "ionic" and "Covalent" those are "ideal bonds". Actual chemical bonds have distinctiveness of both of the theoretical extremes (ionic and covalent). The percent ionic character is related to the electro negativity difference ΔEN.

Final answer:

The bond character changes as electronegativity varies, with greater differences leading to a bond with more ionic character, causing unequal electron distribution and partial charges on the atoms.

Explanation:

Electronegativity is a measure of the tendency of an atom to attract electrons or electron density towards itself. The character of a bond—whether it is ionic, polar covalent, or nonpolar covalent—is determined by the difference in electronegativity between the two bonded atoms. When there is a significant difference in electronegativity, the bond is considered ionic, meaning one atom effectively donates an electron to the other. As the electronegativity difference decreases, the bond becomes more covalent, with electrons shared more equally between atoms. In the case of a polar covalent bond, the electrons are shared unequally, leading to a partial charge on each atom and creating a dipole moment (μ = Qr).

The larger the difference in electronegativity, the more polarized the electron distribution in the bond. This causes the atom with higher electronegativity to have a partial negative charge, while the atom with lower electronegativity has a partial positive charge. In summary, as the difference in electronegativity increases, the ionic character of the bond increases, creating a more pronounced uneven distribution of electron density.

Answer: b.more acidic the solution

Explanation:

pH is the measure of acidity or alkalinity of a solution.  Acids are substances which gives [tex]H^+[/tex] ions when dissolved in water.

[tex]HX\rightarrow H^++X^-[/tex]

pH is calculated by taking negative logarithm of hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

[tex]pH=log\frac {1}{H^+}[/tex]

Thus as pH and [tex]H^+[/tex] are inversely related, a solution having lower pH will have more amount of [tex]H^+[/tex] concentration , a lower amount of [tex]OH^_[/tex] concentration and will be more acidic.

Final answer:

The lower the pH of a solution, the more acidic it becomes. The pH level measures the concentration of hydrogen ions in a solution, and a lower pH indicates a higher concentration, hence a higher acidity.

Explanation:

The lower the pH of a solution, the more acidic the solution becomes. The pH scale, which ranges from 0 to 14, is used to measure the acidity or alkalinity of a solution. A pH of 7 represents a neutral solution, while a pH below 7 is acidic, and a pH above 7 is alkaline (basic). The pH level quantifies the concentration of hydrogen ions (H+) in a solution. Therefore, a lower pH indicates a higher concentration of hydrogen ions, which translates to a higher acidity.
