Answer: The total pressure in the container is 2.00 atm

Explanation:

We are given:

Initial pressure of $PCl_5$ = 1.00 atm

For the given chemical equation:

$PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)$

After the completion of reaction:

Pressure of $PCl_3$ = 1.00 atm

Pressure of $Cl_2$ = 1.00 atm

Total pressure of the container = $p_{PCl_3}+p_{Cl_2}=[1.00+1.00]=2.00atm$

Hence, the total pressure in the container is 2.00 atm

Answer:

The total pressure in the container is 2 atm (Option B)

Explanation:

Step 1: Data given

The initial pressure of the PCl5(g) is 1.00 atm

Volume of the container = 1.00 L

Step 2: The balanced equation

PCl5(g) ⇋ PCl3(g) + Cl2(g)

Step 3: Calculate the total pressure in the container

1mol of ideal gas has a pressure of 1 atm

If 1 mol of PCl5 completely decomposes into 1 mol PCl3 and 1 mol Cl2

Then the pressure for 1 mol PCl3 and 1 mol Cl2 is for both 1 atm

The total pressure would be 2*1 atm = 2 atm

The total pressure in the container is 2 atm

Ionic compounds generally have lower boiling and melting points than covalent compounds.

Anuta_ua [19.1K]

Answer:

The given statement is false.

Explanation:

Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.

The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.

What would happen to a eukaryotic cell if its all mitochondria were destroyed

atroni [7]

Golgi complex would happen to a eukaryotic cell if its all mitochondria were destroyed. Basically the cell will not be able to produce the ATP required for the cell to function properly. This can lead to cell death as well. I hope that this is the answer that has actually come to your great help.

Balance each skeleton reaction, use Appendix D to calculate E°cell, and state whether the reaction is spontaneous:(b) Hg₂²⁺(aq)

Olegator [25]

The given reaction is not spontaneous.

We must recognize changes in oxidation states that take place across elements in order to balance these equations. To accomplish this, keep in mind following guidelines:

A neutral element on its own has an oxidation number of zero.For a neutral molecule, the total number of oxidations must be zero.The net charge of an ion is equal to the sum of its oxidation numbers.In a compound: hydrogen prefers +1, oxygen prefers -2, fluorine prefers -1.In a compound with no oxygen present the other halogens will also prefer -1.

One of the mercury atoms is oxidized from +1 to +2 in the simple aqueous ion, for a loss of 1 electron.

Oxidation half-reaction:

$0.5 Hg^{2+} _{2} (aq)$ → $Hg^{2+} (aq) + 1e^-$
