Study Notes
Types of Chemical Bonds in Water
- Water (H₂O) contains two types of chemical bonds: polar covalent bonds and hydrogen bonds.
- Polar covalent bonds are formed between oxygen and hydrogen within a single water molecule, leading to a dipole moment due to electron sharing.
Hydrogen Bond Location
- Hydrogen bonds occur between water molecules, where the positively charged hydrogen atoms of one molecule attract the negatively charged oxygen atoms of adjacent molecules.
- These bonds are crucial for the unique properties of water, such as high surface tension and boiling point.
Polar Covalent Bond Location in Chemical Body
- Within a water molecule, the polar covalent bond exists between the oxygen atom (more electronegative) and the hydrogen atoms (less electronegative).
- This bond results in a partial negative charge on the oxygen and partial positive charges on the hydrogens, creating a polar molecule.
Irreversible and Reversible Chemical Reaction Difference
- Irreversible reactions proceed in one direction, resulting in products that cannot revert to reactants under normal conditions (e.g., combustion).
- Reversible reactions can go both ways, with reactants converting to products and vice versa, allowing for an equilibrium state (e.g., synthesis of ammonia).
Chemical Reactions Difference Between Reactants and Products
- Reactants are the starting substances that undergo change during a chemical reaction, while products are the resulting substances formed.
- The energy, composition, and arrangement of atoms differ between reactants and products, often resulting in a change in physical and chemical properties.
