B, D in the diagram represents the transition from liquid to gas. A phase diagram is a sort of figure that is used in physical chemistry.

A phase diagram is a sort of figure that is used in physical the field of chemistry engineering, mineralogy, as well as materials science to demonstrate the conditions (pressure, temperatures, volume, etc.) that exist when thermodynamically different phases (such solid, liquid, or gaseous states) arise and coexist at equilibrium.

Lines of equilibrium, also known as phase boundaries, or circumstances under which different phases may exist at equilibrium, are typical elements of a phase diagram. Phase changes take place along equilibration lines. Despite their frequent occurrence, metastable phases are not equilibrium phases, hence they are not depicted on phase diagrams. B, D  in the diagram represents the transition from liquid to gas.

Therefore, B, D in the diagram represents the transition from liquid to gas.

120 degrees

(c) sp and sp2 hybrid orbitals:

109.5 degrees

Explanation:

The angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Hybrid orbitals are defined as the outcome of a model that generates a new set of orbitals by combining atomic orbitals on a single atom.

It can also be defined as a form of atomic orbital that emerges when two or more atomic orbitals of an isolated atom mix.

It can be defined as the forming new atomic orbitals by combining two or more common atomic orbitals.

The process which forms hybrid orbitals are known as hybridization.

There are mainly five types of hybridization.

Thus, the angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Water has three states of matter namely gas, solid or ice form and liquid. Molecules in solid state are not able to move since they are tightly packed.

Molecules can move in liquid state and they moves easily in gaseous state.

Every substance have three states, that are gas, liquid and solid. In solid state, molecules are tightly packed and are unable to move apart. In liquid state, molecules have some space to move and motion of liquid is easy.

The movement of molecules in a substance depends on the space allotted for them or called the volume. More volume between molecules, easy to move apart.

Gaseous state is composed of molecules located far apart from each other and they diffuse easily. Therefore, motion in three states of water is different and moves faster in gaseous state.

The final pressure in the container if the temperature remains constant is 68.3 kPa.

Given the following data;

To find the final pressure in the container if the temperature remains constant, we would use Boyle's Law:

Mathematically, Boyle's law is given by the formula;

[tex]P_1V_1 = P_2V_2[/tex]

Where;

Substituting the values into the formula, we have;

[tex]205[/tex] × [tex]4 =[/tex] [tex]12P_2[/tex]

[tex]820 = 12P_2\\\\P_2 = \frac{820}{12}[/tex]

Final pressure, P2 = 68.3 kPa

Therefore, the final pressure in the container if the temperature remains constant is 68.3 kPa.

The final pressure of the gas mixtures is 72.48 atm.

The given parameters;

The number of moles of the gases is calculated as follows;

[tex]number \ of \ moles \ of \ oxygen = \frac{88}{16} = 5.5 \ moles\\[/tex]

[tex]number \ of \ moles \ of \ argon = \frac{33}{40} = 0.825 \ moles\\[/tex]

The total number of moles of the gas mixture;

= 5.5 + 0.825

= 6.325 moles

The final pressure of the mixture is calculated as follows;

PV = nRT

[tex]P = \frac{nRT}{V} \\\\P = \frac{6.325\ mol \times (0.0821 \ L.atm/mo.K) \times (62+273)}{2.4 \ L} \\\\P = 72.48 \ atm[/tex]

helloo!!!!!!! I am 12 :)

Answer:

See below

Explanation:

2C2H6 + 7O2 = 4CO2 + 6H2O

2C2H2 + 5O2 = 4CO2 + 2H2O

A lot of this is trial and error.  I start from left to right.  For the first reaction, you had

C2H6 + O2  =  CO2  +  H2O

You have 2 carbons on the left so you can try adding a 2 in front of the carbons on the right and keep going from there.  Now you have

C2H6  +  O2  =  2CO2  + H2O

You now have 2 C on each side.  C2 is the same as 2C.

The next step is to look at the hydrogens on the left.  You have 6 so you need 6 on the right.  You can add a 3 in front of the H on the right.  The H already has a subscript of a 2 so having the 3 in front will now make it 6H.  You now have this

C2H6  +  O2  =  2CO2  +  3H2O

So your C are equal (2 on each side) and your H is equal (6 on each side).  All that is left is the O.  So far you have 2 on the left but you have 7 on the right (4 from the 2CO2 and 3 more from 3H2O).  Since you have an even number on one side and an odd number on the other, there is no way to make this work.  So it's time to start over.

My next step was to put a 2 in front of C2H6 and keep going as we did above.  Start with this

2C2H6   + O2  = CO2  + H2O

You have 4 C on the left.  So you need to add a 4 in front of CO2 to get 4 C on the right.  Now you have this

2C2H6  +  O2  =  4CO2  +  H2O

Now on the left you have 12 H (2 in front times the 6 subscript on the H).  You need to have 12 on the right.  We can get that by putting a 6 in front of the H2O ( again the 6 in front times the 2 subscript of the H is 12 total).  You have this now

2C2H6  +  O2  = 4CO2  +  6H2O

You now have 4 C on both sides, 12 H on both sides.  All that is left now is the O.

On the right side, you have a total of 14 ( 8 from the 4CO2 and 6 from 6H2O).  So you'd need to add 7 in front of the O2 to make it 14.

You're done.  4 C on both sides, 12 H on both sides and 14 O on both sides.

The second equation I just did the same process.
