Your patient gets a prescription for 62.5 mcg (micrograms, mg) of digoxin in liquid form. The label reads 0.0250 mg/mL. How many
blsea [12.9K]

Answer:

2.5 militers (mL) of digoxin solution

Explanation:

if         1 microgram = 0.001 miligram

then   62.5 micrograms = X miligrams

X = (62.5 × 0.001) / 1 = 0.0625 miligrams

the we calculate the number of militers of digoxin needed by the patient:

if we have           0.0250 miligrams of digoxin in 1 mililiter of solution

then we have     0.0625 miligrams of digoxin in X mililiters of solution

X = (0.0625 × 1) / 0.0250 = 2.5 militers (mL) of digoxin solution

(a) Write the reaction for the overall oxidation of propane (C3H8) with oxygen to produce CO2 and water.
Pavlova-9 [17]

Answer:

Oxidation is the loss of electrons, that is, addition of electronegetive elements, example is addition of oxygen. Also, removal of electropositive elements, example is removal of hydrogen.

Explanation: a) In the presence of excess oxygen, propane burns in air, which gives the following chemical equation:

C3H8 + 5O2⇒ 3CO2 + 4H2O +Heat

b) When insufficient oxygen or too much oxygen is present for complete combustion, the following equation is given:

2C3H8 + 9O2 ⇒ 4CO2 + 2CO + 8H2O + Heat

c) At the anode( negative terminal): O∧2- ⇒ O + e

Oxygen accepts electron.

d) At cathode ( positive terminal): H∧+ + e∧- ⇒ H

Hydrogen donates electron

d) Nernst equation for reversal potential is given as follows:

E= RT/zF  In{ion outside cell}/{ion inside cell}= 2.303 RT/zF In{ion outside cell}/{ion inside cell}

A technical machinist is asked to build a cubical steel tank that will hold 195 L of water. Calculate in meters the smallest pos
Aleks04 [339]

Answer:

The smallest possible inside length of the tank is 0.579 m.

Explanation:

As we know that

1 m^3 = 1000 L

Thus, volume of 195 liter tank is also equal to 0.195 cubic meter

The volume of a cube is equal to x^3, where, x is the length of the side of the cube

With the give condition,

x^ 3 = 0.195

Solving the above equation, we get -

x = (0.195)^{\frac{1}{3})}\\x = 0.579

The smallest possible inside length of the tank is 0.579 m.
