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].

Calculate the number of moles in 400g of Tio2

Answers

Answer:

5.01 moles

Explanation:

Calculate the number of moles in 400g of Tio2

first, write the formulas correctly

Calculate the number of moles in 400g of TiO2

capitalize the first letter of your elements

the molar mass of TiO2 is

47.88 +2X16.00 =47.88  +32.00 = 79.88 gm/mole

(to 3 sig fig = 79.9 gm/mole

400 gm/79.9 gm/mole = 400/79.9 mole gm/gm =

400/79.9 moles = 5.01 moles

if 10.5 grams of liquid water is boiled how many grams of water vapor will then form ?

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.
