Acids and Bases
In the Acids and Bases leveled reader, fundamental chemistry science facts are explained through simply written text and colorful, fun illustrations. Children will discover that everything we see, touch, and taste is made of atoms. Atoms are the fundamental building blocks of matter and can link together to make molecules, which have different properties.Acids and bases are two types of molecules that have different properties. Sour molecules, such as those in lemons, are often acids; and molecules that are slippery, such as those in soap, are often bases. Acid molecules contain an “H” group made of one hydrogen atom. Base molecules contain an “OH” group made of an oxygen atom bonded to a hydrogen atom. “H” groups and “OH” groups give acids and bases their different properties.A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.

Why are there double bonds in unsaturated fatty acids?
Double bonds are present in unsaturated fatty acids because they contain fewer hydrogen atoms than saturated fatty acids. The double bonds create kinks in the carbon chain, preventing the molecules from packing tightly together. This results in a lower melting point and a more fluid consistency at room temperature. The presence of double bonds also allows for more flexibility and bending in the fatty acid chain, which is important for biological functions such as cell membrane structure and signaling.

Are organic acids, aliphatic acids, and carboxylic acids the same?
No, organic acids, aliphatic acids, and carboxylic acids are not the same. Organic acids are a broad category of acids that are derived from living organisms and can include carboxylic acids, as well as other types of acids such as phenols and sulfonic acids. Aliphatic acids are a specific subset of organic acids that are characterized by having straight or branched carbon chains. Carboxylic acids are a type of organic acid that contain a carboxyl group (COOH) and are a subset of aliphatic acids. Therefore, while all carboxylic acids are organic acids and aliphatic acids, not all organic acids or aliphatic acids are carboxylic acids.

How do inorganic acids differ from carboxylic acids?
Inorganic acids are typically derived from inorganic compounds and do not contain a carboxyl group (–COOH) like carboxylic acids. Inorganic acids are usually simpler in structure and are often strong acids, meaning they completely dissociate in water to release hydrogen ions. Carboxylic acids, on the other hand, contain a carboxyl group and are organic compounds that are typically weaker acids compared to inorganic acids. Additionally, carboxylic acids are commonly found in nature and are important in biological processes.
-
What is the structural formula notation for peptide bonds of amino acids?
The structural formula notation for peptide bonds of amino acids is typically represented as follows: H2N-CHR-CO-NH-CHR-CO-NH-CHR-CO-... In this notation, H2N represents the amino group of one amino acid, CHR represents the alpha carbon and its attached side chain, CO represents the carbonyl group, and NH represents the amino group of the next amino acid in the peptide chain. This sequence continues for each additional amino acid in the peptide chain.

Why are simple organic acids also called alkanes acids?
Simple organic acids are also called alkanes acids because they are derived from alkanes, which are saturated hydrocarbons. These acids have a carboxyl group (-COOH) attached to an alkyl group, making them a type of alkane derivative. The simplest organic acid, formic acid, is derived from methane, the simplest alkane. The naming convention reflects the structural relationship between alkanes and organic acids.

Why are simple organic acids also called alkanic acids?
Simple organic acids are also called alkanic acids because they are derived from alkanes, which are saturated hydrocarbons. These acids contain a carboxyl group (-COOH) attached to an alkyl group, which is a hydrocarbon chain. The alkyl group in these acids is derived from alkanes, hence the name alkanic acids. Examples of alkanic acids include acetic acid (derived from methane) and formic acid (derived from methanol).

Do strong acids conduct electricity better than weak acids?
Yes, strong acids conduct electricity better than weak acids. This is because strong acids completely dissociate into ions in solution, resulting in a higher concentration of ions available to carry an electric current. On the other hand, weak acids only partially dissociate, leading to a lower concentration of ions and therefore lower conductivity.

Why are amino acids divided into polar and nonpolar amino acids?
Amino acids are divided into polar and nonpolar categories based on the chemical properties of their side chains. This division is important because it helps to understand how amino acids interact with each other and with their environment. Polar amino acids have side chains that contain functional groups such as hydroxyl, amine, or carboxyl groups, which can form hydrogen bonds and interact with water. Nonpolar amino acids have side chains that are hydrophobic and do not readily interact with water. This classification is crucial for understanding protein structure, function, and interactions.
