When wood id burnt, 30 grams of ash are formed due to the chemical changes that occurred.
The missing 370 grams are evaporated into the air where they form other particles and substances.
Methylation is a process that involves Mercury metal. Methylation is a process by which a methyl groups are added to the DNA molecule. when it occurs it can change the activity of a DNA segment without changing the sequence, additionally, when located in a gene promoter it may act to repress gene transcription.
- Endothermic reaction : so the energy of product is higher than the energy of reactant.
- Catalyst lowers the activation energy so it increase the rate of reaction.
- The graph is attached:
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
