Answer:

The alkaline earth metals (IIA elements) lose two electrons to form a 2+ cation. Aluminum, a member of the IIIA family, loses three electrons to form a 3+ cation. ... And all of them form an anion with a single negative charge. The VIA elements gain two electrons to form anions with a 2- charge.

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

12. Complete each of the following word equations for synthesis reactions.
Vlada [557]

Explanation:

12)

a) Sodium + oxygen = ?

When sodium reacts oxygen its forms sodium oxide as a product.

4Na(s)+O_2(g)\rightarrow 2Na_2O(s)

b) magnesium + fluorine = ?

When magnesium reacts with fluorine its forms magnesium fluoride as a product.

Mg(s)+F_2(g)\rightarrow MgF_2(s)

13)

a) 2HgO(s)\overset{\Delta }\rightarrow 2Hg(l)+O_2(g)

Decomposition of mercury(II) oxide on heating gives out mercury and oxygen gas.

b)2H_2O(l)\overset{Electricity}\rightarrow 2H_2(g)+O_2(g)

The electrolytic decomposition of water gives out hydrogen gas amd oxygen gas.
