Four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

<h3>What are binary ionic compounds?</h3>

Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.

Now, four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

How many moles are in 3.45 g of Na2O?Round your answer to three significant
Neporo4naja [7]

Answer: There are 0.056 moles present in 3.45 g of Na_{2}O.

Explanation:

Given : Mass = 3.45 g

Moles is the mass of substance divided by its molar mass.

Hence, moles of Na_{2}O (molar mass = 61.98 g/mol) is as follows.

Moles = \frac{mass}{molar mass}\\= \frac{3.45 g}{61.98 g/mol}\\= 0.056 mol

Thus, we can conclude that there are 0.056 moles present in 3.45 g of Na_{2}O.

docker41 [41]

Answer:

The correct option for question 1 would be:

a bilayer containing lipids with hydrophilic head groups pointing inward and hydrophobic tail groups facing the solvent (extracellular fluid and cytosol).

The correct option for question number two would be: proteins.

Explanation:

The membranes present phospholipids that act as selective barriers between the intracellular and extracellular space, allowing an internal balance in relation to the external one.

Its conformation is mostly phospholipids, fatty acids, proteins (from transmembrane to intermembrane or external)
