What is one example of an everyday molecule?

Chemistry

Tamiku [17]3 years ago
4 0

Answer:

Hydrogen

Explanation:

Just to provide some background, an element is a pure substance consisting of only one type of atom. An atom is the smallest constituent of matter. All elements are comprised of a single type of atom (e.g., gold is composed of gold atoms, helium of helium atoms, phosphorus phosphorus, and so on).

A molecule is a group of two or more atoms. They can be the same atom (homonuclear), such as or different atoms (heteronuclear).

Some examples of homonuclear molecules include:

Hydrogen  (H2)  

Nitrogen  (N2)  

Phosphorus  (P4)  

Some examples of heteronuclear molecules include:

Carbon dioxide  (CO2)  

Sulfuric acid  (H2SO4)  

Methane  (CH4)

A key difference between the James-Lange theory and the Cannon-Bard theory of emotion is that in the first, physiological change
mariarad [96]

Answer:

<h2>1. precede emotional experience</h2><h2>2. occur at the same time</h2>

Explanation:

William James and Carl Lange gave a theory about a type of emotion is called a James-Lange theory. According to this theory, physiological arousal creates an emotional experience. According to this theory, physiological changes are the primary condition while emotion is felt when brain interacts with the information obtained from the body.  

                    According to the Cannon-Bard theory, the emotional feeling occurs when the dorsal thalamus is stimulated. In this theory, physiological changes and emotional experiences take place at the same time.

What is the answer??
Leya [2.2K]

Covalent bonds are between two non-metals. Hydrogen and oxygen are non-metals. Hence is is, "yes, hydrogen and oxygen are nonmetals."

Under strongly acidic conditions aldoses become oxidized to dicarboxylic acids called aldaric acids
horrorfan [7]

Under strongly acidic conditions aldoses become oxidised to dicarboxylic acids called aldaric acids

<h3>What are aldaric acids?</h3>

The formula for aldaric acids is HOOC-(CHOH)n-COOH, and they are a kind of sugar acids in which the sugars' terminal hydroxyl and carbonyl groups have been substituted by terminal carboxylic acids.

Aldoses are often oxidised with nitric acid to produce aldaric acids. The open-chain (polyhydroxyaldehyde) form of the sugar interacts in this reaction.

Aldoses that have both the hydroxyl function of the terminal carbon and the aldehyde function of the first carbon completely oxidised to carboxylic acid functions are referred to as aldaric acids. (Aldonic acid is produced by oxidising just the aldehyde, whereas uronic acid is produced by oxidising only the terminal hydroxyl group.) Like unoxidized sugars, aldaric acids cannot produce cyclic hemiacetals, but they occasionally can form lactose.

Are electrons protons and neutrons the smallest particles?.
Norma-Jean [14]
<h2><u>Answer</u> : No</h2>

<h3><u>Brief explanation</u>:</h3>

<em>John Dalton considered atom as the smallest particle but later on this theory failed due to discovery of electron,proton and neutron. This three are the subatomic atomic particle. Later on Murray Gell-Mann discovered the quarks which forms the neutrons and protons and determine overall charge on them. </em>

<u>Conclusion</u> - Electron, proton and neutron are subatomic particles not smallest particles.
