Answer:

Mg3N2 + 6H20 → 2NH3  + 3Mg(OH)2

Explanation:

The reactant side(left side) of the equation is given as magnesium nitride and  water.

magnesium nitride  = combination of magnesium ion and nitrogen ion

Magnesium is the positive end or cation while Nitrogen is the anions or negative end

Mg2+  and  N3-

cross multiply the charges

Mg3N2 = magnesium nitride

H20 = water

Reactant = Mg3N2 + H20

Product  = NH3  + Mg(OH)2

For ammonia

N3- and H+

cross multiply the charges

NH3

For Magnesium hydroxide

Mg2+ and (OH)-

cross multiply the charges

Mg(OH)2

Combining the reactant and the product

Mg3N2 + H20 → NH3  + Mg(OH)2

Balancing the equation, we make the number of atom on the left side equal to the right side.

Mg3N2 + 6H20 → 2NH3  + 3Mg(OH)2

on the reactant side

Mg = 3

N = 2

H = 12

O = 6

On the product side

N  = 2

H = 6 + 6 = 12

Mg = 3

O = 6

SpyIntel [72]

Answer:

Ba^2+ = Barium ion [Cation]

Cl-= Chloride ion  [Anion]

Explanation:

Ba(OH)2 + HCl = BaCl2 + H2O is the reaction that happens.

You make an ionic compound which is soiuble in water Barium Chloride. The cation is Ba^2+ = Barium ion, Cl^ - = Chloride ion

Postive ions are cations and negative ions are anions thus

Ba^2+ = Barium ion [Cation]

Cl-= Chloride ion  [Anion]

how many ml of a 22.5% (v/v) ethanol solution would you need to measure out in order to have 12.5 ml of ethanol ?
Aleks [24]
Volume percent<span> or </span>volume/volume percent<span> (v/v%) is used when preparing solutions of liquids. It will have units of volume of the smaller composition substance over the volume of the solution. We calculate as follows:

12.5 mL ethanol = .225 mL ethanol / 1 mL solution ( V )
V = 55.56 mL of the 22.5 % by volume ethanol solution is needed
