Answer:
Acid solutions contain hydrogen ions. The higher the concentration of hydrogen ions, the lower the pH. Strong acids are fully ionised but weak acids are only partly ionised in solution.
Example:
Hydrochloric acid is a strong acid and ethanoic acid is a weak acid.
Answer:
The fractional saturation for hemoglobin is 0.86
Explanation:
The fractional saturation for hemoglobin can be calculated using the formula
Where 
is the fractional oxygen saturation
is the partial pressure of oxygen
is the partial pressure when 50% hemoglobin is saturated with oxygen
and h is the Hill coefficient
From the question,
= 40 mm Hg
= 22 mm Hg
h = 3
Putting these values into the equation, we get
Hence, the fractional saturation for hemoglobin is 0.86.
The value of the coefficient x in the balanced equation can be calculated as :
<span>
x/y </span>= <span><span>26.4[mL]/</span><span>6.6[mL<span>]
x/y = 4</span></span></span>
