Across
- 3. is just a way of using the formulas to indicate the chemicals that were involved in the chemical reaction
- 4. is a chemical reaction that results in an equilibrium mixture of reactants and products
- 5. give the number of molecules (or atoms) involved in the reaction
- 7. is a solution in which the solvent is water
- 10. is a useful guide for predicting the products of metal displacement reactions
- 11. a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
- 12. a substance participating in a chemical reaction, especially one present at the start of the reaction.
- 13. is a reaction in which one of the reactants is oxygen. ▪ The other reactant is usually a hydrocarbon.
- 15. is the symbolic representation of a chemical reaction in the form of symbols and formulate
- 16. is a substances that speeds up a chemical reaction; but is not consumed by the reaction
- 18. a substance obtained from another substance through chemical change.
Down
- 1. is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another - that is, one element is replaced by another in a compound.
- 2. a chemical equation shows the chemical formulas of substances that are reacting and the substances that are produced. The number of atoms of reactants and products need to be balanced.
- 6. is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
- 8. is an ion that exists as a reactant and a product in a chemical equation.
- 9. a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds
- 14. are equations that show only the soluble, strong electrolytes reacting (these are represented as ions) and omit the spectator ions, which go through the reaction unchanged.
- 17. is the amount of product obtained in a chemical reaction
