Answer:

The answer to your question is below

Explanation:

Alpha decay occurs when a radioactive atm emits an alpha particle (Helium atom).

a)      ²⁵⁶Ra      ⇒      ²⁵²₈₄ Po  +   ⁴₂He

b)     ²¹⁹Rn       ⇒      ²¹⁵₈₂Pb    +   ⁴₂He

c)      ²¹¹Po      ⇒      ²⁰⁷₈₀Hg    +   ⁴₂Hg

d)      ²¹⁰Pb     ⇒     ²⁰⁶₇₈Pt      +   ⁴₂Hg

Question 20 (2 points)
sveta [45]

Answer:

becomes runoff and finds its way back to the ocean

Explanation:

Precipitation refers to rainfall that reaches the earth.

Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.

When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.

Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean

Control of Blood pH by respiratory rate.
nata0808 [166]

Answer:

A) During this procedure ( hypoventilation ) The CO2 in the arterial blood vessels and the lungs increases and this drives the PH level in the system lower, and the equilibrium will shift to the right. this is because the Blood-PH level is controlled by CO2 - bicarbonate buffer system

B) The blood PH may rise to 7.60 during Hyperventilation because the removal of CO2 from the lungs causes the increase in  H^+ which is directly proportional to the increase in Blood PH levels

C) Hyper ventilation before a dash would be useful because it will remove excessive Hydrogen ions and and raise the Blood PH levels in preparedness of the production of acids like Lactic acid

Explanation:

A) During this procedure ( hypoventilation ) The CO2 in the arterial blood vessels and the lungs increases and this drives the PH level in the system lower, and the equilibrium will shift to the right. this is because the Blood-PH level is controlled by CO2 - bicarbonate buffer system

CO_{2} +H_{2} O ⇄ H^+ + HCO^-_{3}

B) The blood PH may rise to 7.60 during Hyperventilation because the removal of CO2 from the lungs causes the increase in  H^+ which is directly proportional to the increase in Blood PH levels

C) Hyper ventilation before a dash would be useful because it will remove excessive Hydrogen ions and and raise the Blood PH levels in preparedness of the production of acids like Lactic acid
