The reaction shown below occurs in the blood between hemoglobin (Hb) and oxygen.
OlgaM077 [116]

Answer:

A, B, C

Explanation:

Notice that this reaction involves double arrows, meaning this represents an equilibrium reaction in which we observe a forward reaction (combination of hemoglobin and oxygen) and a reverse reaction (decomposition of the oxyhemoglobin complex).

Upon inhalation of oxygen, it accesses the blood of a person and binds to hemoglobin, so the following reaction proceeds to the right.

Similarly, the opposite process takes place in muscles, oxyhemoglobin is decomposed back into hemoglobin and oxygen.

The equilibrium constant reaction is relatively high, since at standard conditions, this is a spontaneous reaction, hemoglobin combines with oxygen without any additional external source of energy.

Answer: has zero mass

is an electron

has a -1 charge

is electromagnetic energy

Explanation:

A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.

The beta particle released is basically a electron with -1 charge and no mass.

General representation of beta particle in the form of _Z^A\textrm {X} given as _{-1}^0e

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element
