Would you expect the Mg3[Cr(CN)6]2 to be diamagnetic or paramagnetic? Explain your reasoning.
bixtya [17]

Answer:

paramagnetic

Explanation:

The complex ion is : [Cr(CN)₆]³⁻

Oxidation state of Cr in [Cr(CN)₆]³⁻ is:

x + (-1)6 = -3

x = +3

CN⁻ is a strong field ligand which can result in  pairing of the electrons.

The electronic configuration of Cr is:

1s²2s²2p⁶3s²3p⁶3d⁵4s¹

The electronic configuration of Cr³⁺ is:

1s²2s²2p⁶3s²3p⁶3d³

<u>These 3 electrons will be singly present in the 3 degenerate t₂g orbitals and per Hund's rule, pairing will not occur in the same level energy orbitals. So , no. of unpaired electrons will be 3 and the complex will be paramagnetic.</u>

how many calories of energy are given off to lower the temperature of 100.0g of iron from 150.0°C to 35.0°C?
jeyben [28]

Answer:

ΔT = Tfinal − Tinitial = 150°C − 35.0°C = 125°C

given the specific heat of iron as 0.108 cal/g·°C

heat=(100.0 g)(0.108 cal /g· °C )(125°C) =

  100x 0.108x125= 1350 cal

Energy can be .................. From one form to another................. Can be burned to make heat or electricity.
nataly862011 [7]

Answer:

transferred

Energy

Explanation:

Energy is the ability to change the state of bringing about a work leading to movement or generating electromagnetic radiation. There are actually many forms of energy. So, kinetic energy is a form of energy related to the movement of a body. The combustion, in turn, retrieves the potential energy chemical contained in fuels. Solar panels capture light energy to transform it into electrical energy.
