Answer: Quantity required for a 0.125 mg dose is 2.5 ml
Explanation:
Given : Available concentration of Digoxin Elixir = 0.05 mg/ml.
That is 0.05 mg is present in 1 ml of the solution. We need to find quantity required for a 0.125 mg dose.
This can be found using unitary method.
For 0.05 mg, the quantity required is = 1ml
Thus for 1 mg , the quantity required is =
For 0.125 mg , the quantity required is =
Thus quantity required for a 0.125 mg dose is 2.5 ml
Answer:
An iron atom located on the heme portion of hemoglobin
Explanation:
Oxygen is attached to an <em>iron</em> atom located on the<em> heme</em> portion of hemoglobin.
Hemogoblin is a protein present in the red blood cells of several vertebrates. The main function of this protein is to transport oxygen through blood. The heme portion consists of an organic cyclic compound that contains 4 nitrogen atoms, which bond to an iron atom.
Answer:
65.2%
Explanation:
It is given that :
Therefore, 60 g of nitrogen oxide will produce 92 g of nitrogen dioxide
or 60 kg of nitrogen oxide will produce 92 kg of nitrogen dioxide
or 1500 kg of nitrogen oxide will produce of nitrogen dioxide
Therefore the percentage yield = (Actual yield / Expected yield) x 100
percentage yield =
Percentage yield = 65.217 %
Answer:
The mixture is not in equilibrium, the reaction will shift to the left.
Explanation:
<em>Based on the equilibrium:</em>
<em>Fe³⁺+ HSCN ⇄ FeSCN²⁺ + H⁺</em>
<em>kc = 30 = [FeSCN²⁺] [H⁺] / [Fe³⁺] [HSCN]</em>
Where [] are concentrations at equilibrium. The reaction is in equilibrium when the ratio of concentrations = kc
Q is the same expression than kc but with [] that are not in equilibrium
Replacing:
Q = [10.0M] [1.0M] / [0.1M] [0.1M]
Q = 1000
As Q > kc, the reaction will shift to the left in order to produce Fe³⁺ and HSCN untill Q = Kc
