Alabama thread!

Program doesn't let you move on without the correct answer

 

Give us some of the questions

 

Current question:

A certain chemical reaction releases
265.kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes
3.54J of heat energy to raise the temperature of this calorimeter by 1°C. Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 13.7°C. How would you calculate the number of moles of reactant that were consumed?

Set the math up. But don't do any of it. Just leave your answer as a math expression.

Also, be sure your answer includes all the correct unit symbols.

 

I have a list I made a while back. I'll try to find it. It shows the excuses that worked and the ones that didn't.

 

Can't give a computer an excuse, the teacher doesn't even look at it. It automatically pushes the grade over

 

Ah I remember those.

Unfortunately, even if I was still brushed up on chemistry, I wasn't very good at it.

 

Actually, hold on. I think I got it.

 

This is just dimensional analysis conversions, but I can't get the damn celsius to cross out

 

I halfway remember doing this in Chem 101.

Convert all units from kJ to J.

Set up equation to solve for moles of reactant consumed as Y using 3.54J as the independent variable X.

 

Start with 3.45 J / 1 c

 

Got it, just had to flip everything upside down

 

End my sentence here but I think it's:

 

It just shows Cullman is the central location

 

Thanks, I think I'm getting better at this

 

Check with me again when you get to computational analysis, vibrations, or controls.

 

I see him all the time on my way to work.

 

Will do, is that in physics?

 

Check with me when you get to thermodynamics, I'll make it my bitch. Again.

 

Haha bet

 

Lolllllllllll
