- Q1What happens to the temperature change in an exothermic reaction?It decreasesStays the sameIt increase30s
- Q2In an exothermic reaction where does the energy transfer to?From the surroundings to the reactionFrom the reaction to the surroundingsIt is created in the reactionIt is destroyed in the reaction30s
- Q3What is an endothermic reaction?Energy exits the reaction from the surrounding. Temperature stays the same.Energy exits the reaction from the surrounding. Temperature decreasesEnergy enters the reaction from the surroundings, temperature decreaseEnergy exits the reaction from the surrounding. Temperature increases.30s

- Q11What piece of equipment do you need to determine whether a reaction is exothermic or endothermic?Weighing scaleThermometerBunsen burnerStopwatch30s
- Q12What is WRONG with this method?The student has not specified whether we how long he left the thermometerThe student used too little acidThe student used too much magnesiumThe student has not recorded the starting temperature30s
- Q13An exothermic reaction is when energy...Is destroyed in the reactionEnters the reaction from the surroundingExits the reaction to the surroundingIs created in the reaction30s
- Q14In exothermic reactions there is always...no change in temperatureA temperature decreaseA temperature increaseA large increase in temperature30s
- Q15Instant ice packs work by cooling down when two chemicals inside the pack react. What reaction is this?ExothermicRespirationEndothermicCombustion30s
