Below is a list of molecules with different chemical characteristics. Knowing that all molecules will eventually diffuse across
Ilia_Sergeevich [38]

Answer:

c. estrogen > propanol > alanine > sodium

Explanation:

The phospholipid bilayer is formed by amphoteric lipids, the nonpolar region is inside the bilayer, so the diffusion of nonpolar molecules are easy (nonpolar reacts with nonpolar) and generally occurs passively (without loss of energy). With the increase of the polarity, the diffusion became difficult and slow. All the molecules are shown below.

Estrogen has two points of polarity in its hydroxides, but the carbon rings stabilize the molecule, and it has low polarity. Then, propanol has only one hydroxide and is the second-lowest polar molecular. Alanine has two points of polarity because oxygen and nitrogen have high electronegativities. Then, the ion sodium has a charge and has no stabilization such as the molecules, so it is the most difficult to diffuse.

. Given the reaction 2HgO → 2Hg + O2 , how many moles of elemental mercury will be obtained by the decomposition of 1 mole of Hg
AveGali [126]

Answer:

one mole of HgO will give one mole of Hg.

Explanation:

Given data:

Moles of HgO = 1 mol

Moles of Hg = ?

Solution:

Chemical equation:

2HgO → 2Hg + O₂

Now we will compare the moles of Hg with HgO from balance chemical equation.

                  HgO   :     Hg

                    2       :      2

                     1       :      2/2×1 = 1 mol

So, one mole of HgO will give one mole of Hg.

Sodium chloride is dissolved in water.<br> Which ions are present in the electrolyte?
IgorC [24]
It is the polar nature of water that allows ionic compounds to dissolve in it. In the case of sodium chloride (NaCl) for example, the positive sodium ions (Na+) are attracted to the negative pole of the water molecule, while the negative chloride ions (Cl−) are attracted to the positive pole of the water molecule.
