| Question | Answer |
|---|---|
| A division or category in a system which divides things into groups or types. | Classification |
| Each of the things has the same strength or importance. | Balance |
| An equation that doesn't include spectator Ionics . OH-(aq) + H+(aq) → H₂O | Net ionic equation |
| An ion that appears unchanged in both sides of a reaction arrow. K+(aq) + OH-(aq) + H+(aq) + NO³-(aq)→ H₂O(l) + K+(aq) + NO³-(aq) So, K+(aq) + NO³-(aq) | Spectator ion |
| An equation in which ions are explicitly shown. K+(aq) + OH-(aq) + H+(aq) + NO³-(aq)→ H₂O(l) + K+(aq) + NO³-(aq) | Ionic equation |
| Substance that undergoes change in a chemical reaction and written on left side of reaction | Reactant |
| Substance formed in chemical reaction and written on right side of arrow | Product |
| Matter is neither created nor destroyed. During a chemical reaction, the bonds between atoms can be broken and new bonds can be formed in the products. Atoms cannot be gained,lost,or changed into another element during a chemical reaction. | Law of conservation of mass |
| A chemical equation in which the numbers and kinds of atoms are the same on both side of the reaction arrow. Chemical equation must be balanced to show the same number of atoms in the reactants and products in order to follow Law of conservation of mass. | Balanced chemical equation |
| A number placed in front of a formula to balance a chemical equation | coefficient |
| An insoluble solid that forms in solution during a chemical reaction. | Precipitate |
| An ionic compound formed from reaction of an acid with a base. | Salt |
| A liquid in which a solid substance has been dissolved. | Solution |
| A liquid which can dissolve other substances. | Solvent |
| A substance dissolved in another substance. | Solute |
| AgNO₃ (aq)+ KCl(aq) → AgCl + KNO ₃(aq) What type of reaction? | Precipitation reaction |
| HCl(aq)+NaOH(aq)→H₂O(l)+NaCl(aq) What type of reaction? | Acid - base neutralization reaction |
| Mg(s) + I ₂(g) → MgI(s) what type of reaction? | Redox reaction |
| The amount of a compound that will dissolve in a given amount of solvent at a given temperature. | Solubility |
| There are several rules to predict whether a precipitation reaction will occur upon mixing aqueous solution of two ionic compounds. | Solubility Guidelines |
