Why water dissloves so many different substances?
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
What is The breaking apart of certain polar substances to form ions when dissolved in water known as what?
The breaking apart of certain polar substances to form ions when dissolved in water is known as ionization. This process occurs due to the interaction between the polar water molecules and the solute molecules.
Can a pure substance be dissolve?
Yes, pure substances can dissolve in certain solvents or environments. The solubility of a pure substance depends on the interactions between the molecules of the substance and the molecules of the solvent.
What kinds of substances cant be dissolved in water?
Substances that cannot be dissolved in water are typically nonpolar molecules, such as oil, fats, and wax. In general, substances with strong intermolecular forces that are not easily disrupted by water molecules will not dissolve in water. Examples include hydrophobic molecules like hydrocarbons and certain gases like oxygen and nitrogen.
What Semipermeable object that can pass through it what cannot?
A cell membrane is a semipermeable object that allows certain substances, such as water and small molecules, to pass through it while blocking larger molecules and ions. This selective permeability is important for controlling the movement of substances in and out of the cell.
What substances can pass through the cell membrane?
Substances that can pass through the cell membrane include small molecules like water, oxygen, and carbon dioxide, as well as certain ions and lipid-soluble molecules. Larger molecules and charged ions typically require specific transport proteins to cross the membrane.
Are poler substances attracted to the other poler substances or to the nonpoler substances?
Polar molecules are attracted to other polar molecules with an opposite charge.
What is a attraction between molecules of different substances?
Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
Why do molecules in cold things move more slowly compared to molecules in warmer substances?
Molecules in cold substances move more slowly compared to molecules in warmer substances because lower temperatures reduce the energy of the molecules, causing them to move less and at a slower pace.
What substances absorb waists in water better?
Substances that are porous and have a high surface area tend to absorb water better. Materials like activated carbon, silica gel, and certain types of clays are known for their ability to absorb water efficiently. These substances have many small spaces where water molecules can be trapped, allowing for effective absorption.
What are some molecules?
Two or more atoms joined together; the smallest unit of many substances.
What are long chains of molecules that make up many substances in cells?
i want the answer u are stupid
