i need to know what the variables q=mc delta t stand for, i have an exam over it tommorow and i have no clue what this formula is....i was absent the day we went over it in class....thanks
Edit: in the equation the delta is a trinagle...if that helps at all

Q = m*c*(delta T)
Q = heat energy
m = mass
c = specific heat
delta t = change in temperature (= final - initial temp)

I believe m is for mass, c is heat capacity, and delta t is average temperature..hope that helps.

McDelta T. It's a sandwich at McDonald's, and it's endorsed by Mr. T. He wants to show how he's changed over the years, and how now he caters the foo'.

yep, q=heat
m=mass
C=spec. heat
delta t = change in temp (Tf-Ti)

and you can set them equal to each other for a system...

mCdelta t = mCdelta t

That is correct, after multiplying MC and Delta T you'll have the amount of heat energy (in Joules) that is absorbed (+ answer) or released (- answer) in a given reaction. If M C or Delta T is the unknown variable take the necessary algebraic steps to solve for it (I'm assuming you passed algebra since you're in chemistry).
