Help me please
I’m failing these classes so I have the answers guyssssss
1. the balloon is hot.
2.Heat is transmitted; the reaction is exothermic.
3.calorimeter
4. the amount of energy stored in the bonds
5. highly endothermic
y’all i tried so hard yayyyyy yes i just got a 100% thank you!!!! Thank you so much my grade is low in chemistry @student needing help is ok 5/5 thank you my grade will go up thanks to you love you can confirm the answers. 100% correct thanks, i checked brrainly, and nothing came up, but i found this… tysm bruh, u da best fam, thnx
