Which property increases with increasing atomic number for both the alkali metals and the halogens?

Chemistry

To answer this question,you must be knowledgeable on periodic trends. When the atomic number increases, that means that the trend of the property must increase both across the period and down a group. The alkali metals are the elements in the leftmost column, while the halogens are the second-to-the-last column. From the periodic trends shown in the picture,<em> the property must be atomic radius.</em>

Draw the Lewis structure for CH3CH2O2H?
kotegsom [21]

Answer:

hydroperoxyethane

Explanation:

tomsFor the Lewis structure we have to remember that all the atoms must have <u>8 electrons</u> (except for hydrogen). In this structure, we have three types of atoms, Carbon, Hydrogen and Oxygen. So, we have to remember the <u>valence electrons</u> for each atom:

-) Carbon : 4 electrons

-) Hydrogen: 1 electron

-) Oxygen: 6 electrons

We can start with the "CH_3" part. We can put 3 hydrogen bond arroun the carbon. We can use this same logic with  "CH_2". Finally for oxygens, we can put it one bond with CH_2 and a bond between oxygens with a final bond with hydrogen to obtain <u>hydroperoxyethane</u>.

See figure 1 for further explanations.

Acetic acid has the formula ch3cooh. At low ph this protonated, uncharged form is the most abundant form in solution. As the ph
slamgirl [31]

Acetic acid is a weak acid. So, the undissociated acid molecules exist in equilibrium with the dissociated form. The equilibrium representing the weak acidic nature of acetic acid is,

CH_{3}COOH(aq)+H_{2}O(l)CH_{3}COO^{-}(aq)+H_{3}O^{+}(aq)

The interior of the cell membrane is hydrophobic. So, the membrane allows uncharged species (hydrophobic) to pass through it. Charged groups cannot easily pass through the membrane. We can say acetic acid can easily pass through the membrane when compared to the charged form acetate ion. At low pH, more of the molecule will cross the membrane as most of the acetic acid will be in undissociated and uncharged form at a lower pH.

pK_{a}of acetic acid is around 4.8. So at a pH value less than 4.8, we can say the more of the acetic acid molecules can cross the membrane.
