Answer:
3.0 g daily dose
Explanation:
First of all, the given dose is measured in milligrams per kilogram of body and the mass of this patient is given in pounds. This means we have to begin this problem by converting the units.
Convert the mass into kilograms:
Knowing that the dose is 15.0 mg per kilogram of body, one dose is equal to:
This is a single dose. If we wish to calculate the daily dose, since it's used twice, we get:
Propane : ).............................................
Answer:
-285.4 J/K
Explanation:
Let's consider the following balanced equation.
HCl(g) + NH₃(g) ⇒ NH₄Cl(s)
We can calculate the standard entropy change for the reaction (ΔS°r) using the following expression.
ΔS°r = 1 mol × S°(NH₄Cl(s)) - 1 mol × S°(HCl(g)) - 1 mol × S°(NH₃(g))
ΔS°r = 1 mol × 94.6 J/K.mol - 1 mol × 187 J/K.mol - 1 mol × 193 J/K.mol
ΔS°r = -285.4 J/K

Answer:
11 atoms
Explanation:
The formula for lead(II) bicarbonate is: Pb(HCO3)2.
Atoms in Pb(HCO3)2:
Pb=1, H=1×2, C=1×2, O=3×2
1+1×2+1×2+3×2
=1+2+2+6
=11 atoms
