Hydrogen Cyanide, HCN, is a poisonous gas. The
1 answer:
mass of NaCN = 0.539 g
Further explanation
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2NaCN (s) + H₂SO₄ (aq) ⇒ Na₂S0₄ (aq) + 2HCN (g)
MW HCN = 27,0253 g/mol
MW NaCN = 49,0072 g/mol
Assume there is 1 kg air, and mass of HCN = 300 mg
mol HCN :
mass 300 mg = 0.3 g
NaCN : HCN = 2 : 2(mole ratio from equation), so :
mol NaCN = mol HCN = 0.011
mass NaCN :

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 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
