What is the enthelpy of combustion of magnesium?

AI Thread Summary
The enthalpy of combustion of magnesium can be determined using the reaction equation Mg + 1/2O2 --> MgO. To find this value, one can refer to the enthalpy of formation for magnesium oxide (MgO), which is -601 kJ. This value is essential for calculating the enthalpy of combustion. Resources such as textbooks or online databases can provide the necessary data for these calculations. Understanding the heat of formation is crucial for solving combustion enthalpy problems.

[SOLVED] What is the enthalpy of combustion of magnesium?

Homework Statement


Determine the enthalpy of combustion of Magnesium.

Mg + 1/2O2 --> MgO

magnesium + half oxygen -> magnesium oxide.


The Attempt at a Solution



I am not sure how to calculate this since I don't know where to start. Is there a specific value for this? Or, is there a way we could get these values from a chart or somewhere?

I need help. Thanks.

Review the definition of heat of formation and then reexamine your combustion equation.

They should be at the back of your book or try the Index if all fails.
 
Thanks very much guys for your responses. I found it on the net and basically I had to look for enthalpy of formation of MgO to get my answer. It's -601 kJ.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
