Describe how phospholipids form a barrier between water inside the cell and water outside the cell

Chemistry
1 answer:
Lynna [10]3 years ago
6 0
<span>Phospholipids would have to form a phospholipid bilayer in order to achieve water on the outside and water inside. This is because the nonpolar tails of the phospholipids are facing each other in a water environment because they cannot interact with the water, only their own tails, while the phosphate heads of the molecule face the periphery of the tails and interact with water. Micelles are the simplest examples of these.</span>

oksano4ka [1.4K]

Answer:

The true statement is:

They are formed when atoms of different elements combine.

Explanation:

Compounds are formed when atoms of different elements combine.

Atoms of different elements combine with each other to attain stable electronic configuration.

The atoms can combine with each other in two different ways:

1) By sharing the electrons

2) By exchanging electrons

When they share electrons with each other, they form a covalent bond.

When they exchange electrons, they form an ionic bond.

Which equation shows how to calculate how many grams (g) of KOH would be needed to fully react with 4 mol Mg(OH)2? The balanced
bazaltina [42]
Mole ratio:

MgCl₂ + 2 KOH = Mg(OH)₂ + 2 KCl

2 moles KOH ---------------- 1 mole Mg(OH)₂
moles KOH ------------------- 4 moles Mg(OH₂)

moles KOH = 4 x 2 / 1

= 8 moles of  KOH

molar mass KOH = 56 g/mol

mass of KOH = n x mm

mass of  KOH = 8 x 56

= 448 g of KOH 

hope this helps!
