Sir I have a question, so if I put a cold water bottle out from the fridge and now it is gaining heat in order to balance its temperature with the room temperature so will it count as an endothermic reaction?

This guy is the reason why I am understanding chemistry

dear mr cognitio, I hope you are making a portion of my teachers salary as she completely relies on your videos to “teach”

how do we know wether the products have high energy or not? so we can either place them low or high?

@LG-tt2qz

A good chemistry textbook should present a list of bond energies called enthalpies. Like a mass balance, you only have to count de bonds in a given compound adding theír respective enthalpies. And a simple enthalpy balance between the products and reactants of a given chemical reaction will let you know whether the reaction is exothermic or endothermic by a calculation known as the reaction enthalpy.

THANKYOU❤

u the best man if i do well tmrw then u gonna be in my will

love the video........really helpful

My honest opinion is that Mr. Cognito is a savior of our exams❤❤❤

Bro honestly can u have a word with my chemistry teacher she dont even teach she js says look in the textbooks ur videos are honestly amazin

I can't get my head around the endothermic reaction because I would have thought that because it requires more energy to start the reaction the reactants would have a stronger bond (more energy) ?? plsss someone help

@NezarIsmail-gv7xb

Yes They have stronger bonds so they need more energy to break these bonds
