C. Sliding Friction (20 characters)
Answer:
1.21 × 10⁻³⁰ m
Explanation:
1 mol of photons causing the change in the conformation of 11-retinal has an energy of 164 kJ. We can find out the wavelength (λ) associated with this energy (E) using the Planck-Einstein equation.
E = h . c . λ⁻¹
where,
h is the Planck's constant
c is the speed of light
λ = h . c . E⁻¹ = (6.63 × 10⁻³⁴ J × s) × (3.00 × 10⁸ m/s) × (164 × 10³ J)⁻¹ = 1.21 × 10⁻³⁰ m
Answer : The amount of codeine in one teaspoonful is, 30 mg
Explanation : Given,
Amount of codeine per fluid ounce = 60 mg
Now we have to determine the amount of codeine present in one teaspoonful.
As we know that:
1 teaspoonful = 0.5 fluid ounce
As, the amount of codeine per fluid ounce = 60 mg
So, the amount of codeine 0.5 fluid ounce =
Thus, the amount of codeine in one teaspoonful is, 30 mg
Explanation:
Medicinal chemistry is a discipline that encloses the design, development, and synthesis of pharmaceutical drugs. The discipline combines expertise from chemistry, especially synthetic organic chemistry, pharmacology, and other biological sciences.
