• Endothermic
• Exothermic

During an endothermic reaction in a beaker if we are part of the surroundings and touched the beaker, it would feel _______. 

• Warm
• Cold

If they energy required to break the bonds is greater than the energy given out by making new bonds the reaction is

• Exothermic
• Endothermic
• Neutralisation

If they energy required to break the bonds is less than the energy given out by making new bonds the reaction is

• Exothermic
• Endothermic
• Neutralisation

In an endothermic reaction the products have 

• more energy than the reactants
• less energy than the reactants
• the same energy as the reactants
• no energy

In an exothermic reaction the products have

• more energy than the reactants
• the same energy as the reactants
• less energy than the reactants
• no energy
