AlexFokin [52]
I believe you are referring zero as the exponent. <span>Any number (except 0) with exponent 0 is defined to mean 1.
</span>

For one thing, there is a rule: 

<span> a^m/ a^m = a^m-m = a^0

</span>But (when a is not equal to <span>0),
</span>
a^m/ a^m = 1

Therefore, we must define a^0 as 1.

Why is rain water slightly acidic
viva [34]

Answer:

Explanation:

Natural Rain:

"Normal" rainfall is slightly acidic because of the presence of dissolved carbonic acid. ... The gases of sulfur oxides and nitrogen oxides are chemically converted into sulfuric and nitric acids. The non-metal oxide gases react with water to produce acids (ammonia produces a base).Natural Rain:

Many drugs are sold as their hydrochloric salts (R2NH2 Cl−), formed by reaction of an amine (R2NH) with HCl. a. Draw the major o
lara31 [8.8K]

Answer:

Here's what I find.

Explanation:

a. Structure

Acebutolol is a secondary amine (basic). It forms a substituted ammonium salt when treated with hydrochloric acid.

The structure of the salt is shown below, with a red arrow pointing toward the positive charge on the N atom.

b. Solubility

The formula of acebutolol is C₁₈H₂₈N₂O₄.

The amide, acetyl, and ether groups confer little solubility to the molecule.

The alcohol and secondary amine do confer some solubility, because they can donate and accept hydrogen bonds.

However, they can each overcome the hydrophobic properties of only three to five carbons, and acebutolol has 18 of them.

The free amine would be preferentially soluble in lipid material (fats)

The protonated amine is ionic and therefore much more soluble in aqueous media (e.g., blood).

c. Marketing

The drug must be delivered to the tissues of the heart, where it blocks the effects of adrenalin. The best way to do this is through the blood, so acebutolol is marketed as the hydrochloride salt.
