  1. 3. a process where substances (reactants) rearrange their atoms to form new substances (products) with different properties
  2. 7. the breaking and forming of chemical bonds, resulting in a change in the chemical composition.
  3. 11. the starting materials in a reaction that undergo a chemical change to form a product
  4. 14. is a type of MIXTURE- in which the individuals substances are not evenly
  5. 17. is matter that can vary in composition
  6. 18. a transformation that alters the appearance or form of a substance, like its state or shape, but does not change its chemical composition or identity
  7. 20. the fundamental, indivisible unit of a chemical element, composed of a nucleus with protons and neutrons, surrounded by electrons, and is the smallest unit that retains the properties of that element
Down
  1. 1. is a type of substance containing atoms of two or more different elements chemically bonded together
  2. 2. a substance's ability to undergo a specific chemical change or reaction, forming new substances with different properties
  3. 4. a fundamental measure of the amount of matter within an object or substance
  4. 5. a measure of the average kinetic energy of the atoms or molecules within a substance
  5. 6. the substances formed as a result of a chemical reaction, where the reactants are transformed into new substances with different properties
  6. 8. is a type of mixture when the individual substances are evenly mixed.
  7. 9. anything that occupies space and has mass, existing in various forms or states (solid, liquid, gas, plasma) and composed of fundamental particles called atoms
  8. 10. a pure form of matter with a uniform and definite composition
  9. 12. presentation of a chemical reaction, using chemical formulas and symbols to show the reactants (starting materials) on the left and the products (resulting substances) on the right, separated by an arrow
  10. 13. the amount of a substance (solute) present in a given amount of space or volume (solution)
  11. 15. a pure substance composed of only one type of atom, characterized by a specific number of protons, and cannot be broken down into simpler substances by chemical means
