The element which is oxidized  in  the  reaction below 
that is

Fe(Co)5  (l) +  2 Hi (g)=  Fe (CO)4 i2(s) +Co (g)+H2 (g)  is

 Fe   this is because   fe in Fe(CO)5  compound move from oxidation state  of  Positive five (5^+)  to  oxidation  state  of  positive  six ( 6^+)  in Fe(CO)4i2  compound.   fe  is  oxidized  by Hi  while  Hi  itself is  reduced  by   Fe,therefore Fe  act as a  reducing agent

Oksanka [162]

Answer:

1.21 × 10⁻³⁰ m

Explanation:

1 mol of photons causing the change in the conformation of 11-retinal has an energy of 164 kJ. We can find out the wavelength (λ) associated with this energy (E) using the Planck-Einstein equation.

E = h . c . λ⁻¹

where,

h is the Planck's constant

c is the speed of light

λ = h . c . E⁻¹ = (6.63 × 10⁻³⁴ J × s) × (3.00 × 10⁸ m/s) × (164 × 10³ J)⁻¹ = 1.21 × 10⁻³⁰ m

Luda [366]

Answer:

The correct answer is beta decay

Explanation:

When a beta particle is emitted from a radioactive atom,at that time the daughter atom that is produced have atomic mass 1 unit more than that of its parental atom.

 In the given reaction a beta particle is emitted from the carbon atom resulting in the formation nitrogen atom,The atomic mass of nitrogen atom is 7dalton which is one unit more than the atomic mass of carbon that is 6 dalton.
