- Q1What is the purpose of an ionic equation?To balance chemical reactionsTo calculate reaction ratesTo determine reaction yieldTo show which atoms or ions are being reduced and which are being oxidized30s
- Q2If lithium chloride reacts with sodium, what are the products formed?Lithium sodium and chlorineSodium chloride and lithium chlorideSodium chloride and lithiumSodium chloride and chlorine30s
- Q3How do you identify spectator ions in an ionic equation?Ions that undergo oxidation onlyIons that disappear in the reactionIons that do not change charge during the reactionIons that gain electrons during the reaction30s
- Q4Which ion is identified as a spectator ion in an ionic equation involving calcium?Cl-Na+Ca2+Mg2+30s
- Q5Which ion is a spectator ion in the ionic equation involving 2Na+ S2- and 2K?S2-S2+K+Na+30s
- Q6In the first equation mentioned, what is the spectator ion? (Li + Cl2)The chloride ion Cl-The sodium ion Na+The lithium ion Li+The calcium ion Ca2+30s
- Q7In the second equation mentioned, what ions can be crossed out as spectator ions? (Na + S)O2- ionsK+ ionsMg2+ ionsNa+ ions30s
- Q8In the last equation mentioned, which ion is considered a spectator ion? (Na + S)Na+S2-Cl-K+30s
- Q9What do you do with spectator ions in an ionic equation?Highlight them in the equationChange their chargeCross them out or delete themCombine them with other ions30s
- Q10What happens to spectator ions in an ionic equation?They are highlighted in boldThey are deleted or crossed outTheir charge increasesThey become the main reactants30s
- Q11What is the role of spectator ions in a chemical reaction?They cause the reaction to occurThey determine the reaction rateThey provide the energy for the reactionThey do not actively participate in the reaction30s
- Q12What defines a spectator ion in a reaction?Ions that do not change their chargeIons that are highly reactiveIons that form new compoundsIons that release energy30s
