What are ion substances and molecule substances?
Ion substances are compounds made up of positively and negatively charged ions, such as sodium chloride (NaCl) or calcium carbonate (CaCO3). These substances are held together by electrostatic forces between the ions. Molecule substances, on the other hand, are made up of covalently bonded atoms, such as water (H2O) or carbon dioxide (CO2). These substances are held together by sharing electrons between the atoms. In summary, ion substances are composed of charged ions held together by electrostatic forces, while molecule substances are composed of covalently bonded atoms held together by shared electrons.

To which substances do the elemental substances belong?
Elemental substances belong to the group of pure substances, which are made up of only one type of atom. These elemental substances are the building blocks of all matter and cannot be broken down into simpler substances by chemical means. Examples of elemental substances include hydrogen, oxygen, carbon, and gold.

To which substances do the elementary substances belong?
Elementary substances belong to the category of pure chemical elements. These are the basic building blocks of matter and cannot be broken down into simpler substances by ordinary chemical reactions. Examples of elementary substances include hydrogen, oxygen, carbon, and iron. Each element is defined by its unique atomic structure and properties.
-
Why do polar substances dissolve in polar substances?
Polar substances dissolve in polar substances because they have similar intermolecular forces. Polar substances, such as water, have a partial positive and partial negative charge, which allows them to form hydrogen bonds with other polar molecules. When a polar substance is added to a polar solvent, the partial charges on the solvent molecules attract and surround the solute molecules, causing them to separate and disperse evenly throughout the solvent. This allows the polar solute to dissolve in the polar solvent, forming a homogeneous mixture.

Can organic substances split and combine with other substances?
Yes, organic substances can split and combine with other substances through chemical reactions. For example, organic compounds can undergo processes such as hydrolysis, where they split into smaller molecules by reacting with water. Additionally, organic substances can also combine with other substances through synthesis reactions, where new organic compounds are formed by combining smaller molecules. These chemical reactions are fundamental to the behavior and properties of organic substances in living organisms and in the environment.

Why do substances dissolve in other substances or not?
Substances dissolve in other substances when the intermolecular forces between the solute and solvent are strong enough to overcome the forces holding the solute together. This allows the solute particles to become surrounded by solvent particles and spread out evenly throughout the solvent. On the other hand, substances may not dissolve in a particular solvent if the intermolecular forces between the solute and solvent are not strong enough to overcome the forces holding the solute together, or if the solute and solvent have incompatible polarities.
