Write the net ionic equation for this reaction occurring in water: ammonium fluoride and magnesium chloride are mixed to form ma

MAXImum [283]

Correct answer: 3. $Mg^{2+}(aq) + 2 F^{-}(aq) --> MgF_{2}(s)$

The given chemical reaction is between ammonium fluoride and magnesium chloride to form magnesium fluoride and ammonium chloride.

The balanced chemical equation representing the reaction will be,

$2NH_{4}F (aq) + MgCl_{2}(aq) -->MgF_{2} (s) + 2NH_{4}Cl (aq)$

The complete ionic equation for the reaction: All the compounds soluble in water (aqueous) will split into ions, $MgF_{2}$ will not split into ions as it is insoluble in water.

$2 NH_{4}^{+}(aq) + 2 F^{-}(aq) + Mg^{2+}(aq) + 2 Cl^{-}(aq) --> MgF_{2}(s) + 2 NH_{4}^{+}(aq) + 2 Cl^{-}(aq)$

The net ionic equation will be:

$Mg^{2+}(aq) + 2 F^{-}(aq) --> MgF_{2}(s)$

Here the spectator ions are $NH_{4}^{+} and Cl^{-}$

How many grams of sodium chloride are present in a 0.75 M solution with a volume of 500.0 mililiters

Ilya [14]

C = 0,75 mol/dm³
V = 500mL = 500cm³ = 0,5dm³

C = n/V
n = 0,75×0,5dm³
n = 0,375 moles

M NaCl: 23+35,5 = 58,5g

1 mole ---------- 58,5g
0,375 ----------- X
X = 0,375×58,5
X = 21,9375g NaCl
