The coordination number (C.N.) is 6 and oxidation number (O.N.) is +4 of the metal atom.

C.N. = 6; O.N. = +4

<h3><u>What </u><u>is Co-ordination number ?</u></h3>
  • The coordination number, also known as ligancy, of a central atom in a molecule or crystal in chemistry, crystallography, and materials science refers to the quantity of atoms, molecules, or ions bound to it.
  • A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.
  • The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.
<h3><u>What is Oxidation number ?</u></h3>
  • The total number of electrons that an atom acquires or loses to establish a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.
  • Each atom involved in an oxidation-reduction reaction has an oxidation number that represents how many electrons it may take, give, or share.

How are waves reflected, absorbed, and transmitted through various materials<br>​
EastWind [94]

Answer:

Electromagnetic Radiation

Explanation:

When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. However, because light can travel through space, it cannot be a matter wave, like sound or water waves.

Are ALL cations positive or negative ions
Mamont248 [21]

Answer:  Ions result from atoms or molecules that have gained or lost one or more valence electrons, giving them a positive or negative charge. Those with a negative charge are called anions and those with a positive charge are called cations. Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. ... And all of them form an anion with a single negative charge. The VIA elements gain two electrons to form anions with a 2- charge.

hope this helps

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.
