Across
- 1. replacement reaction / A chemical reaction in which two reactant ionic compounds swap cations when forming the two product compounds. One of the products often becomes a precipitate.
- 4. / A substance that is produced in a chemical reaction. Normally appears on the right side of a chemical reaction.
- 6. reaction / A chemical reaction yielding a single product from several reactants.
- 7. system / A method of naming different ionic compounds made of the same elements. Man metals can have different oxidation numbers. A Roman numeral in parentheses following the metal's name represents the value of the metal's oxidation number for that compound.
- 9. reaction / A chemical reaction that must absorb heat from its surroundings to occur.
- 10. replacement reaction / A chemical reaction in which one element in a reactant compound is replaced by another reactant element, forming a new compound product. The replaced element becomes one of the products and often forms a precipitate of a gas.
- 11. / A substance that is present before a chemical reaction and takes part in it. Normally appears on the left side of the chemical reaction.
Down
- 2. number / The number of electrons that a bonded atom of ion must gain or lose to return to its neutral state. Are used mainly for writing the formulas of inorganic compounds.
- 3. reaction / Chemical reaction yielding two or more products from a single reactant. It is usually an endothermic reaction.
- 5. reaction / A chemical reaction that liberates heat to its surroundings as it occurs.
- 8. equation / An equation that symbolically represents the identity and amounts of reactants and products that take part in a chemical reaction.
