Across
  1. 5. matter cannot be created or destroyed
  2. 6. the number placed in front of a chemical formula in a balanced equation, indicating the quantity (molecules or moles) of that substance involved in the reaction
  3. 7. when a single, complex compound breaks down (decomposes) into two or more simpler substances or elements, often requiring energy input like heat, light, or electricity
  4. 9. the backward process where chemical products convert back into the original reactants, occurring simultaneously with the forward reaction (reactants to products) in a reversible reaction, eventually reaching a state of dynamic equilibrium where both happen at the same rate, shown by a double arrow (⇌) in equations
  5. 10. the final species resulting from the transformation of reactants.
  6. 12. a substance that takes part in and undergoes change during a reaction
  7. 14. an exothermic chemical process where a substance (fuel) reacts rapidly with oxygen (\(O_{2}\)), releasing energy as heat and light, typically forming water and oxides
  8. 16. a type of chemical reaction where one element replaces another similar element in a compound, resulting in a new element and a new compound
  9. 18. the gain of electrons by a molecule, atom, or ion during a chemical reaction, which decreases its oxidation number
  10. 19. for a chemical reaction to occur, reactant particles (atoms, ions, or molecules) must collide with both sufficient energy (equal to or greater than the activation energy) and the correct geometric orientation
  11. 20. an exothermic chemical process where a substance (fuel) reacts rapidly with oxygen (\(O_{2}\)), releasing energy as heat and light, typically forming water and oxides
  12. 21. the speed at which reactants are converted into products
  13. 22. the minimum energy barrier that reactant molecules must overcome for a chemical reaction to occur, allowing them to transform into products
  14. 23. if a system at dynamic equilibrium is disturbed by a change in conditions (temperature, pressure, or concentration), the system will shift its equilibrium position in a way that counteracts the change and re-establishes a new equilibrium
Down
  1. 1. the loss of electrons by a molecule, atom, or ion, often accompanied by an increase in oxidation state, and can also be described as gaining oxygen or losing hydrogen
  2. 2. a number assigned to an atom in a molecule or ion that shows how many electrons it has lost (positive number), gained (negative number), or shares, representing the degree of electron loss or gain in a chemical compound
  3. 3. a process in which one or more substances (reactants) rearrange their atomic structures to form one or more new substances (products) with different properties
  4. 4. a chemical process where the cations and anions of two different ionic compounds in aqueous solution switch places, forming two new compounds
  5. 8. the branch of chemistry concerned with measuring the rates (speeds) of chemical reactions and determining the factors that influence them, such as temperature, pressure, concentration, and catalysts
  6. 11. a substance that increases the rate of a chemical reaction by reducing the activation energy required, without being consumed or permanently changed in the process
  7. 13. the symbolic representation of a chemical reaction, using formulas, symbols, and coefficients to show the conversion of reactants into products
  8. 14. mass is neither created nor destroyed
  9. 15. the state in a reversible chemical reaction where the forward and reverse reactions occur at the same rate, resulting in constant concentrations of reactants and products over time
  10. 17. the measure of the amount of a dissolved substance (solute) divided by the total amount of the mixture (solvent or total solution)
  11. 22. dissolved in water.
