Which reaction describes an alpha emission?

Chemistry
1 answer:
Tcecarenko [31]2 years ago
7 0

88226Ra→ 86222Rn + 24He is the reaction that describes an alpha emission because radiations are released.

<h3>Describes an alpha emission?</h3>

Alpha radiation occurs when the nucleus of an atom becomes unstable and alpha particles are released in order to restore stability. Alpha decay occurs in elements that have high atomic numbers, such as uranium, radium, and thorium etc.

So we can conclude that 88226Ra→ 86222Rn + 24He is the reaction that describes an alpha emission because radiations are released.

  • Heavy hydrogen commonly  known as deuterium
  • stable isotopes of hydrogen
  • gets its name from the Greek word deuterons means second.
  • has only one proton and one neutron
  • nucleus of the hydrogen's deuterium atom is known as a deuteron containing one proton and one neutron.
  • Deuterium forms chemical bonds that are stronger than regular hydrogen
  • gas deuterium is colorless
  • Deuterated water is used in Magnetic Resonance Spectroscopy.

what is the differential rate expression of the change in B with time? Incorporate elements that describe both its formation and
Ivanshal [37]
The differential rate expression for the rate of change in the concentration of B with time is
-rB = dCB/dt = kCB^n
where k is the rate constant and
n is the order of the reaction
This is assuming that the rate is only affected by the concentration of B and the order of the reaction is in the nth order.

True or false: the smaller the difference between the average experimental value and the correct (true) value the greater the ac
mel-nik [20]

Answer:

True

Explanation:

The accuracy level is usually determined by the difference between the experimental and correct value. It is important to note that the smaller the difference between the average experimental value and the correct (true) value, the more accurate it is.

When the difference is large then it means the accuracy level is low and not up to the required standard.
