8th Grade PS Unit 3: Bonding

12 flashcards · Physics · by Samvid Konchada

1. a mixture in which constituents are distributed uniformly i.e. salt in water

   homogeneous mixture

2. a mixture whose constituents are clearly separate from one another i.e. sand in water or fruit salad

   heterogeneous mixture

3. a mixture made up of two or more different chemical substances which are not chemically bonded. i.e. Trail Mix

   mixture

4. a pure element OR compound that cannot be separated by physical means i.e. Water or gold

   substance

5. In a chemical reaction, these are converted to one or more different substances, the products i.e. Iron & Oxygen

   Reactants

6. In a chemical reaction, reactants are converted to these. i.e. Rust

   Products

7. In this type of chemical reaction, complex chemical compounds are created from simpler ones. i.e. A + B = AB

   Synthesis Reaction

8. In this type of chemical reaction, compounds break down into simpler ones. i.e. AB = A + B

   Decomposition Reaction

9. In this type of chemical reaction, an atom in a molecule is replaced by another atom. i.e. AB + C = AC + B

   Single Replacement Reaction

10. In this type of chemical reaction, 2 atoms in a molecule are replaced by another 2 atoms. i.e. AB + CD = AD + CB

    Double Replacement Reaction

11. In this type of chemical reaction, reactants including oxygen produce water and CO₂ i.e. AB + Oxygen = CO₂ + Water

    Combustion Reaction

12. In this type of chemical reaction, reactants of an acid and base produce water and a salt. It is also a type of double replacement reaction. i.e. Acid + Base = Water + Salt

    Neutralization Reaction
