Which describes the process that forms teflon tm? molecular fluorine (f2) undergoes polymerization. a fluorocarbon polymer break
Stella [2.4K]
Answer:
             T<span>etrafluoroethene (F</span>₂CCF₂<span>) undergoes polymerization describes the formation of Teflon.

Explanation:
                    Polymerization is the process in which small units called as monomers join together repeatedly and forms a long chain macro-molecule called as polymer.
                    In given question the monomer is Tetrafluoroethene because alkenes can undergo polymerization via Addition polymerization via following mechanism.
                            a)  Free Radical Addition Reaction

                            b)  Acid Catalyzed Addition Reaction

                            c)  Base catalyzed Addition Reaction

The formation of Teflon from Tetrafluoroethene is shown below,</span>

zimovet [89]
A wave is a disturbance that carries energy from one place to another. Matter is NOT carried with the wave! A wave can move through matter (a medium). If it must have a medium, it is called a mechanical wave.

How many atoms of phosphorus are in 4.5 grams of tetraphosphorus decoxide?
Alexxx [7]

Answer:

In 4.5 grams of tetraphosphorus decoxide we have 3.85 * 10^22  phosphorus atoms

Explanation:

Step 1: Data given

tetraphosphorus decoxide = P4O10

Molar mass of P4O10 = 283.89 g/mol

Mass of P4O10 = 4.5 grams

Number of Avogadro = 6.022 * 10^23 / mol

Step 2: Calculate moles of P4O10

Moles P4O10 = mass P4O10 / molar mass P4O10

Moles P4O10 = 4.5 grams / 283.89 g/mol

Moles = 0.016 moles

Step 3: Calculate moles of P

For 1 mol P4O10 we have 4 moles of phosphorus

For 0.016 moles P4O10 we have 4*0.016 = 0.064 moles P

Step 4: Calculate number of P atoms

Number of P atoms = moles P * number of Avogadro

Number of P atoms = 0.064 moles * 6.022*10^23

Number of P atoms = 3.85 * 10^22 atoms

In 4.5 grams of tetraphosphorus decoxide we have 3.85 * 10^22  phosphorus atoms
