Chemistry testing endo and exothermic reactions and all dat :>

Test results:

2g 26 26 - 22 22 - 4 4 -

3g 23 22.5 - 17 16 - 6 6.5 -

4g 22.5 21.5 21 14 14 14.5 8.5 7.5 7

5g 21 21 21 12 13 12 9 8 9

6g 20 20.5 - 10 10 - 10 10.5 -

That's a lot of numbers, Joe.

 

Would you like to say what they mean?

Could you be a little clearer in what your question actually is? I assume you need to work out delta H at some point given the data that you have, so could you please indicate where you are having trouble? We are not in the business of doing a person's homework here, so you will need to show some effort.

Thanks Josie!

What is ΔH? We haven't been taught this.

Thanks Josie!

It refers to change in enthalpy.
