Answer:

The formation of magnesium carbonate in the form of a precipitate and sodium sulfate as a byproduct takes place.

Explanation:

When a drop of sodium carbonate is mixed with the magnesium sulfate, the formation of MgCO3, magnesium carbonate as a precipitate, and Na2SO4, sodium sulfate as a byproduct takes place. One can separate magnesium carbonate from the sodium sulfate by using the process of filtration. The chemical reaction that takes place in the process is:

MgSO4 (aq) + Na2SO4 (aq) ⇒ MgCO3 (s) + Na2SO4 (aq)

A separation process in which the formation of solid takes place in a solution after undergoing a chemical reaction is termed as precipitation. The precipitate is the name given to the solid substance that gets produced in the reaction. The precipitate formed can be withdrawn from the solution with the help of a physical separation procedure like filtration.

An order is given to administer methylprednisolone, an anti-inflammatory drug, by IV at a rate of 39 mg every 30 min. The IV bag

Korvikt [17]

Answer:

The Flow rate = 0.0208 mL/min

Explanation:

Data provided:

Rate of dose = 39 mg every 30 min = (39/30) mg/min = 1.3 mg/min

also,

125mg of methylprednisolone is present in every 2 mL

thus,

concentration = (125/2) mg/mL = 62.5 mg/mL

Now,

The flow rate is given as:

Flow rate = Rate / Concentration

on substituting the respective values, we get

Flow rate = (1.3 mg/min) / (62.5mg/mL)

The Flow rate = 0.0208 mL/min

Anastasy [175]

Answer:

215 amu

Explanation:

In the reactants:

There is 1 iron atom, 3 chlorine atoms, 6 hydrogen atoms and 3 oxygen atoms:

Fe: 56 × 1 = 56
Cl: 35 × 3 = 105
H: 1 × 6 = 6
O: 16 × 3 = 48

56 + 105 + 6 + 48 = 215 amu

Hope this helps!
