The chemical name for Fe(HCO₃)₂ is iron(II) bicarbonate.
Iron (II) compounds typically form coordination complexes with ligands that have a higher affinity for binding to the iron ion. Bicarbonate is a relatively weak ligand and is more commonly found as a component of soluble salts, such as sodium bicarbonate (NaHCO3) or potassium bicarbonate (KHCO3).
In this compound, the iron ion has a +2 charge, and the bicarbonate ion (HCO3-) has a -1 charge. When these ions combine, the resulting compound is named accordingly with the Romannumeral (II) to indicate the iron ion's charge.

The light in the electromagnetic spectrum which passes in first case is through opaques objects while in second case it is transparent objects.
The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Just had this question and got it right
Answer:
Magnesium iodide (MgI2)
2.0 moles are represented by 118g of cobalt.
A mole is defined as 6.02214076 ×of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Moles = 2.0023757 = 2.0moles
Hence, 2.0 moles are represented by 118g of cobalt.
