In the chemical compound C2H2, how many pairs of electrons are shared between the two carbon atoms?

2 answers:

4 0

Acetylene (C2H2) has a triple bond between the two carbons. So 3 pairs of electrons. Biomed is talking about ethylene (C2H4).

Explanation:

Acetylene (systematic name: ethyne) is the synthetic compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely utilized as a fuel and a chemical structure block. It is uncertain in its pure form and thus is usually marketed as a solution

Hitman42 [59]

Answer:

The final volume is 3.07L

Explanation:

The general gas law will be used:

P1V1 /T1 = P2V2 /T2

V2 =P1 V1 T2 / P2 T1

Give the variables to the standard unit:

P1 = 345 torr = 345 /760 atm = 0.4539atm

T1 = -15°C = -15 + 273 = 258K

V1 = 3.48L

T2 = 36°C = 36+ 273 = 309K

P2 = 468 torr = 468 * 1/ 760 atm = 0.6158atm

V2 = ?

Equate the values into the gas equation, you have:

V2 = 0.4539 * 3.48 * 309 / 0.6158 * 258

V2 = 488.0877 /158.8764

V2 = 3.07

The final volume is 3.07L

Answer:

0.032 L or 32 mL

Explanation:

Use the dilution equation M1V1 = M2V2

M1 = 9.0 M

V1 = This is what we're looking for.

M2 = 0.145 M

V2 = 2 L

Solve for V1 --> V1 = M2V2/M1

V1 = (0.145 M)(2 L) / (9.0 M) = 0.032 L

What is the necessary voltage to power the electrolysis of molten sodium chloride?

sammy [17]

4V is the necessary voltage to power the electrolysis of molten sodium chloride.

To create sodium metal and chlorine gas, molten (liquid) sodium chloride can be electrolyzed. A Down's cell is the name of the electrolytic cell utilised in the procedure. The liquid sodium ions in a Down's cell are converted to liquid sodium metal at the cathode. Liquid chlorine ions are oxidised to chlorine gas at the anode. Below is an illustration of the reactions and cell potentials:

oxidation: $2Cl^{-} (l)$ → $Cl_{2} (g)$ + $2e^{-}$ E°= -1.36V

reduction: $Na^{+} (l) + e^{-}$ → $Na (l)$ E°= -2.71V

overall : $2Na^{+} (l) + 2Cl^{-} (l)$ → $2Na(l) +Cl_{2} (g)$ E° $_{cell}$ = -4.07V

For this electrolysis to take place, the battery needs to supply more than 4 volts. The only means to obtain pure sodium metal is by this reaction, which also serves as a significant source of chlorine gas generation. Swimming pools and other surfaces are frequently cleaned and disinfected with chlorine gas.
