Hi,
I having troubles with the following problems.
1) Calculate the energy change which will occur when 30g of nitrogen(II) oxide is converted to nitrogen(IV) oxide by reacting with oxygen in the air.
2)Copper(II) oxide can be reduced to copper metal and water by using hot hydrogen gas. Calculate the energy change when 54g of water is formed by this process.
I think my problem with these problems are I don't fully understand the concepts. If you could explain to me which formula I would use and why, I would really appreciate it.
Thanks so much
