Enthalpy Stoichiometry Part 2: How to Find Heat Released

[@ireneh.9519]

Awesome video! By the way, your thermochemistry notes are incredible! 👍🏽

[@melissamaribel]

Thank you so much Irene! I'm so glad you like the notes 💕

[@crystalroy2469]

The struggle with chemistry is real! Especially online learning! This is my first time taking chemistry; I'm in college studying nursing. I was doing well until this and spent 2 days working through the last 2 problems on my homework and just couldn't grasp it. I wish I found this channel sooner, you've explained this in a way I can understand. I'm not feeling much less anxious and stressed about this topic. Subscribed!

Ms. Maribel, from the bottom of my heart, thank you so much for your videos! Your lessons are so concise and easy to follow and not filled with jibber jabber (like a certain Hank Green... xD)

[@melissamaribel]

😂Haha jibber jabber! Thank you Manu, glad you are liking the lessons 🤓

2 terms into chemistry. Exam in two weeks . Been trying to understand Stoichiometry for the past 5 days now. Came across your channel today and even though i still dont fully understand stochiometry. You have definitely helped . Thank you

[@Liboo52]

Yours are the best chemistry question example explanation videos I’ve ever seen

[@cli4rd]

We tackled this in our class but I didn't get why the answer was positive even though the sign in enthalpy is negative. This was really helpful.

My thermochemistry test for AP Chem is this Thursday and I'm completely clueless:( But, this helps a ton so thank you!! Please post the other parts if u can!!(before Thursday?)

[@melissamaribel]

Hope your test went well!

[@tbpion9460]

thanks a million!! you are the best at explaining and simplifying everything! I did really well on my chem exam thanks to you!

[@brookejenkins2516]

I have been subscribed to your channel for a little while, and you are so helpful! I will be checking out these guides --- hopefully before this final! You're so great --- thank you sooooooooooo much!!!!

[@AgnessLumbala]

You are really helping me very much 🙏🙏🙏

[@hannahfarkas8160]

I was just freaking out all night thinking i couldn’t understand this till i came here. Thanks so much

[@rocketeditor]

really helpful for me right now, thank you!

[@ejperez3604]

What book guide include this kind of thermochemical equations, and specific heat heat of fusion,vapozation, ?

[@redengineer1753]

So I have to know heat from other similar reaction in order to count it?

[@dangerousboy3887]

What would happen if we calculate the moles by the formula mole= mass in g/molar mass

[@zahraasalih2042]

how would you find the triangle H if your not given that?

[@angelrai3612]

Oh my gosh, thank you so much!!

[@NomceboMandisa-mi7ht]

You are the best ever❣️

[@ItJackL]

I stg your videos are going to let me pass this class

[@rachanapatel3304]

2:50 shouldn't it be 5 hydrogen?

[@melissamaribel]

For C2H5OH, there is an extra hydrogen at the very end next to the oxygen so that's why there is a total of 6.

[@rachanapatel3304]

Chemistry with Melissa Maribel oh hahah I didn't even notice!😂

[@ETF4everA7X]

My teacher is awful! Thank you so much for maintaining this channel’your the best!

[@Carol-AnneGarrett]

THANK YOU SO MUCH!

[@apriljoycerosita9595]

what if the only given was 40 kJ/mol? should i multiply -40kJ/mol to 1mol only, to know the heat released?

[@kristabeldakul2637]

You are the best❤❤❤❤

[@ThePurpleAlphabet]

Awesome - I love the chemistry notes! ;)

[@melissamaribel]

😉Thank you love!

[@arbineryan3555]

Thank you so much for the videos!

[@emmanuelchisom140]

please i am still confused about the calculations of pH and pOH put me through

[@jamaridaguilar4708]

Thanks so much

[@minecraftgamers2767]

Saved me so much time lol thx

[@cydthekid3809]

your channel is so clutch

[@prasannasantan1646]

Awesome video, it helped me a lot..

[@yourfavourite8144]

Very helpful

[@Leoocarmona]

I LOVE YOU SO MUCH THANK YOU ur the reason I’m passing chemistry 🧪 💚

[@melissamaribel]

You are so welcome Leo!! 🤓

[@cesarvadim9628]

Thank you so much.

[@tutstorial8474]

can I ask how to solve this one? I really don't know how to this but since the topic is about combustion maybe you can help me on this. 😅 An engine used to pump water raises up 1000lb water 100ft. In doing this, 1 lb of fuel having a HEAT OF COMBUSTION 1000 Btu/lb was burned. What percentage of heat produced was transformed into useful work?

[@buckleygs23]

My friend Edward thanks you. ;)

[@boluwatifeajiboye6979]

You re the best ♥️😘😘
