Answer : The volume required to administer a 75 mcg dose are, 0.75 mL
Explanation : Given,
Concentration of Digoxin = 0.1 mg/mL
That means, 0.1 mg of Digoxin present in 1 mL of solution.
Mass of dose = 75 mcg = 0.075 mg
Conversion used : (1 mcg = 0.001 mg)
Now we have to determine the volume required to administer a 75 mcg dose.
As, 0.1 mg of Digoxin required in 1 mL of solution
So, 0.075 mg of Digoxin required in 
of solution
Thus, the volume required to administer a 75 mcg dose are, 0.75 mL
The electons are in the atmosphere
The ionic radius increases.
Each time you move down to the next Period, you are adding an extra shell of electrons.
Each shell is further from the nucleus than the one before it, so the .
The image below illustrates the increase in ionic radius as you go down a Group.
Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
- In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
- Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
- The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products. Therefore, if a graph of concentration and time is plotted, the rate of reaction is simply the slope of the graph.
