Describe in general terms the structure of ionic solids such as nacl
allochka39001 [22]
<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>

If a solution containing 117.63 g of silver chlorate is allowed to react completely with a solution containing 10.23 g of lithiu
GuDViN [60]

Answer:

18.8 g

Explanation:

The equation of the reaction is;

AgClO3(aq) + LiBr(aq)------>LiClO3(aq) + AgBr(s)

Number of moles of AgClO3 = 117.63 g/191.32 g/mol = 0.6 moles

Number of moles of LiBr = 10.23 g/86.845 g/mol  = 0.1 moles

Since the molar ratio is 1:1, LiBr is the limiting reactant

Molar mass of solid AgBr = 187.77 g/mol

Mass of precipitate formed = 0.1 moles * 187.77 g/mol

Mass of precipitate formed = 18.8 g

Write the charge balance for a MgSO 4 and NaNO 3 solution that contains H + , OH − , Mg 2 + , HSO − 4 , SO 2 − 4 , MgHSO + 4 , M
irga5000 [103]

Answer :

MgSO_4 solution contains Mg^{2+} and SO_4^{2-}

NaNO_3 solution contains Na^{+} and NO_3^{-}

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

The given compounds are, MgSO_4 and NaNO_3

MgSO_4 is an ionic compound which is formed by the combination of Mg^{2+} cation and SO_4^{2-} anion.

and,

NaNO_3 is an ionic compound which is formed by the combination of Na^{+} cation and NO_3^{-} anion.
