How to Calculate the Heat Released in Magnesium Combustion Reactions?

[blackblanx]

Homework Statement

Heat of Reaction for the combustion of Magnesium

Data:

A. Mass MgO = 0.7975g Volume 1M HCl = 97.5 ml
Temp.intial = 24.2 C Temp.final = 29.3 C \DeltaT = 5.1 C

B. mass Mg 0.0896g Volume 1M HCl 89.5 ml
Temp. intial = 24.1 c Temp. final = 28.4 c \DeltaT = 4.3 C

With the following data above I need to calculate the heat realsed for each reaction

Homework Equations

Need to use Q=Mc \DeltaT also the question tells you to assume one cal of heat is required to change the temperature of one ml of solution one degree Celsius

The Attempt at a Solution

not sure were to begin

You actually have all of the data you need...

Just turn the last sentence into something more mathematical.

"one calorie of heat is required to change the temperature per 1 degree C per mL of solution"

Is the same as

\frac{Q}{T \cross V}

which describes a specific heat capacity, I believe.
