A Lewis acid is an electron-pair acceptor.
Bronsted-Lowry bases are species that can accept a proton.
Arrhenius acid gives 
ions.
<h3>What is acid?</h3>
An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
A Lewis acid is therefore any substance, such as the 
ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
Bronsted-Lowry bases are species that can accept a proton due to a high-energy pair of electrons being present.
According to Arrhenius, the acids are the hydrogen-containing compounds which give ions or protons on dissociation in water and bases are the hydroxide compounds which give 
ions on dissociation in water.

Answer: iodine 131 iodine 132 isotopes
Explanation:
Explanation:
a. Vanillin(4-hydroxy-3-methoxybenzaldehyde):
In its structure hydroxl group will be present on para position of the benzaldehyde ring and methoxy group on meta position.
b. Thymol (2-isopropyl-5-methylphenol):
In its structure isopropyl group will be present on ortho position of the phenol ring and methyl group on meta position.
c. Carvacrol (5-isopropyl-2-methylphenol):
In its structure isopropyl group will be present opposite to methyl group which is present ortho position in a phenol ring.
d. Eugenol (4-allyl-2-methoxyphenol):.
In its structure allyl group will be present on para position of the phenol ring and methoxy group on ortho position.
e. Gallic acid (3,4,5-trihydroxybenzoic acid):
In its structure hydroxyl group will be present on both meta positions and on para position of the benzoic acid ring.
f. Salicyl alcohol (o-hydroxybenzyl alcohol):
In its structure, 
group is linkedto benzene ring and in respect to that hydroxyl group is present at ortho position of the ring.
Answer:
174,957.143 grams of potassium and 89,228.478 grams of potassium nitrate will be needed.
Explanation:
Mass of nitrogen = 27 lbs = 12,247 g
1 lbs = 453.592 g
Moles of nitrogen = 
According to reaction, 1 mole of nitrogen is produced from 5 moles of potassium and 1 mole of potassium nitrate.
Then 874.786 mol of nitrogen will be obtained from :
of potassium.
Then 874.786 mol of nitrogen will be obtained from :
of potassium nitrate.
Mass of 4,373.928 moles of potassium:
of potassium
Mass of 874.789 moles of potassium nitrate:
of potassium nitrate
