No it’s just like a snowflake there are all different
Because molecules have other chemical and physical properties than the containing atoms !
No some can be very strong like lightning
Dichloromethane does not exhibit hydrogen bonding properties in chemical reactions because it does not have hydrogen atoms bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine. Hydrogen bonding occurs when hydrogen atoms are bonded to these electronegative atoms, allowing for strong intermolecular forces. Dichloromethane, with its chlorine atoms, does not have the necessary hydrogen atoms for hydrogen bonding to occur.
H20 is a chemical property because it refers to the chemical formula for water, which consists of two hydrogen atoms bonded to one oxygen atom. This composition describes the specific arrangement of atoms in a water molecule, which is a characteristic of its chemical identity.
Sugar is a chemical compound. It is a carbohydrate that consists of carbon, hydrogen, and oxygen atoms. Its structure and composition give it certain physical properties, such as being sweet and soluble in water, but overall it is considered a chemical substance.
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
Methane and hydrogen are different gases because they have different chemical compositions and properties. Methane (CH4) is composed of carbon and hydrogen atoms, while hydrogen (H2) is composed solely of hydrogen atoms. Additionally, they have different physical properties such as boiling and melting points.
Both H2O (water) and D2O (deuterium oxide, or heavy water) have the same chemical structure, consisting of two hydrogen atoms bonded to one oxygen atom. The difference between the two lies in the isotopes of the hydrogen atoms, with H2O containing regular hydrogen (H-1) and D2O containing deuterium (H-2).
Hydrocarbons have only hydrogen and carbon atoms. They also burn well.
Ammonia is compound because it is made of a nitrogen atom bound to three hydrogen atoms. In this form, it has different physical and chemical properties than either nitrogen or hydrogen.
None: Hydrogen and chlorine are both chemical elements and therefore do not contain any other chemical substances.
An explosion is an example of a chemical change because the arrangement of the atoms has been altered.
