does SO3 2- show delocalized bonding

Answers

Answer 1

Answer:

YES

Explanation:

SO3 2-DOES  show delocalized bonding

delocalized bonding occurs when there is a resonance structure and the electronic bonds are a delocalised "cloud" around the species

Answer 2

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore SO₃²⁻ show delocalized bonding.

What is Ions?

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state.

SO₃²⁻ show delocalized bonding as there is a resonance structure and the electronic bonds are a delocalized "cloud" around the species

Therefore SO₃²⁻ show delocalized bonding.

Answers

nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. This membrane seems to be continuous with the endoplasmic reticulum (a membranous network) of the cell and has pores, which probably permit the entrance of large molecules. The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

Choose the names of the substances for reactants of the equation
2H2 + O2—— 2H2O

Answers

the reactants are hydrogen and oxygen NOT water, WATER is the product

The names of the substances for the reactants in the chemical equation 2H₂ + O₂ → 2H₂O are; Hydrogen gas (H₂) and Oxygen gas (O₂). Option A and C is correct.

Hydrogen gas (H₂) - This is the molecular form of hydrogen, consisting of two hydrogen atoms bonded together.

Oxygen gas (O₂) - This is the molecular form of oxygen, consisting of two oxygen atoms bonded together.

In a chemical equation, the reactants are the substances that undergo a chemical reaction to form new products. In this case, the reactants are hydrogen gas (H₂) and oxygen gas (O₂). The arrow (→) in the equation represents the direction of the reaction, indicating that hydrogen gas and oxygen gas react to form water (H₂O).

The coefficient 2 in front of H₂ and H₂O indicates that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The balanced chemical equation shows the stoichiometry of the reaction, indicating the number of molecules of each reactant and product involved in the reaction.

Hence, A. C. is the correct option.

How would you gather data to in order to determine the density of a marble

Answers

The average mass of a marble can be determined by dividing the total mass of the marbles by the total number of marbles: average mass of a marble.

To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.

Use the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).

To determine the density of a marble, we must know its mass and volume.

In order to determine the density of any substance we need to know its mass and volume.

Let's understand "Density".

The density of a substance is its mass per unit volume. It is represented with "ρ" this symbol.It can be given by the formula which is shown below: ρ= [tex]\frac{m}{V}[/tex] where m is the mass of the substance and V is the volume.Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure. The density of a substance can be used to define the substance.

Answers

The heat of vaporization of CH3CN is obtained from the question as 25 KJ/mol.

We can obtain the number of moles from;

PV = nRT

P = 1 atm

V = 1.17 L

n = ?

R = 0.082 atm LK-1mol-1

T = 81.6 °C + 273 = 354.6 K

n = PV/RT

Substituting values;

n =  1 atm × 1.17 L/0.082 atm LK-1mol-1 × 354.6 K

n = 0.04 moles

Using; q = n·ΔHv

q = Heat absorbed

n = number of moles

Hv  = Heat of vaporization

ΔHv = q/n

ΔHv = 1.00 × 10^3/0.04

ΔHv = 25 KJ/mol

EXPLANATION

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO)

2Mg + 0 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

Oxygen exist in nature as O2, diatomic.

so

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO).

2Mg + 02 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

2 moles of Mg produce 2 moles of MgO

1 mole of Mg weighs 24.3 and produces 1 mole of MgO

Mg HAS AN ATOMIC MASS OF 24.3

Mg HAS A MOLAR MASS OF 24.3 +16 = 40.3gm/mole

so 24.3 gm of Mg produce 40.3 gm MgO

set up the ratio

10 gm Mg/x of MgO  = 24.3/40.3

or

10/x = 24.3/40.3

cross multiply and isolate x (use Algebra I)

24.3x =403

x=403/24,3 = 16.58 gm MgO

The city council of a small town wanted to add fluoride to their water so that all the residents would have healthier teeth. The mayor had read that ionic compounds must be used to get the fluoride into water. He looked up fluorine-containing compounds and came up with the following list. ​
NaF NF3 SiF4 CaF2 NH4F​

Using academic vocabulary in paragraph form, discuss the following: ​

Explain which compound(s) could produce fluoride ions in the water. In your response, be sure to include: ​
° which of the listed compounds are ionic and which are covalent. ​
° how ionic and covalent compounds are different. ​
° why only ionic compounds would produce fluoride in water.​

Answers

Answer:NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and  NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.

The compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

The ionic compounds are formed by the transfer of electrons between the atoms of the compounds. The ionic bonds are weaker and are easy to dissociate in the aqueous solution.

The covalent compounds are formed by the sharing of electrons between the atoms. Since there is sharing, there has been a strong bond, that has been hard to dissociate.

The Mayor has to release Fluoride in the water, thus ionic compounds are preferred that have the easy release of fluorine.

From the given compounds:

NaF = Ionic compound[tex]\rm NF_3[/tex] = Covalent compound[tex]\rm SiF_4[/tex] = Ionic compound[tex]\rm CaF_2[/tex] =  Ionic compound[tex]\rm NH_4F[/tex] =  Ionic compound

Thus the compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

Answers

Answer:

It depends

Explanation:

This could vary depending on the exact temp, time and minerals. something with alot of salt boils quicker than something without it, so 10.5 grams?

The particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

What are minerals?

Minerals are defined as a naturally crystallized element or chemical compound that was created through geological processes. Natural materials are those that form on their own, such as minerals. Minerals don't droop, melt, or evaporate since they are solids. In contrast to the carbon compounds found in living organisms, minerals are inorganic. Minerals are crystalline: They have a unique atomic composition and arrangement.

Temperature is defined as a measure of hotness or coldness expressed in terms of any number of arbitrary scales that shows the direction that heat energy will naturally flow, i.e., from a hotter body to a colder body. The three temperature scales that are now in use are Kelvin, Celsius, and Fahrenheit. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature.

Thus, the particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.
