How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

Neon is compressed from 100 kPa and 16°C to 500 kPa in an isothermal compressor. Determine the change in the specific volume and
Viktor [21]

Answer:

\Delta v=-0.952m^3/kg

\Delta h=0

Explanation:

In this case, since neon could be considered as an ideal gas, the specific volumes at the first and second state are respectively:

v_1=\frac{Rg*T_1}{p_1}=\frac{0.4119kJ/kg*K*289.15}{100kPa} =1.19m^3/kg\\

v_2=\frac{Rg*T_2}{p_2}=\frac{0.4119kJ/kg*K*289.15}{500kPa} =0.238m^3/kg\\

Thus, the change in the specific volume turns out:

\Delta v=v_2-v_1=0.238m^3/kg-1.19m^3/kg\\\Delta v=-0.952m^3/kg

Which value has sense for the compression.

In addition, the specific enthalpy change just depend on the temperature as it is an ideal gas, therefore, since the process es isothermic:

\Delta h=Cp\Delta T=0

Best regards.

Why is the adhesive property of the pvc plastic important? 1 pt?
GrogVix [38]
 I believe this property is vital since the sticky nature allows the wells to coat easily with the desired antigen by simply adding a small amount of it and allowing it time to incubate. Adhesion is the tendency of dissimilar particles or surfaces to cling to one another ( cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another).
