Just hearing the clock strike midnight made me wonder what becomes of the day that's just been replaced by another. Where does it go? Is it possibly recycled or reincarnated at some point? If you have any idea, please let me know.

I can't understand why in my math book 385/165 = 5x7x11/3x5x11
And it doesn't even explain WHY 385/165 was reduced to 5x7x11/3x5x11
Can anyone explain in detail why??

If 0.673g of Cu is reacted with excess nitric acid to form 0.990g of copper nitrate, what is the percent yield of copper nitrate in this reaction, from the stoichiometry, it is known tgat 1.000g Cu should form 2.952g of copper nitrate?

I can't solve this problem. Can someone show me how to get this and show me the work?

2O3(g) --> 3O2(g) Delta H= -427 kJ
O2(g) ---> 2O(g) Delta H= 495 kJ
NO (g) +O3(g) --> NO2(g) + O2(g) Delta H= -199 kJ

What is the delta H for the reaction
NO(g) + O (g) --> NO2(g)

It's been commonly told that the opposite of 0 is infinity, but what if there was a point that in a number line that was the imaginary junction between infinity and negative infinity on the number line. This would create a number circle of infinite length and turn a classic X,Y 2-D graph into a stretched out sphere.

Anyone ever think of this. Is there any interesting application of this concept?

1. Structurally, how are biological fuel (sugar) and ‘exhausted’ wastes (CO¬2, H2O) different?

2. Where is the biological ‘energy’ in a molecule of sugar?

3. Glucose is broken down in order to synthesize ATP. Where is the ‘energy’ in glucose? Hint: Glucose is broken down by combining with oxygen to create CO2 and H2O. Hint: Natural gas is methane, CH4. Glucose, water, and carbon dioxide. How do they differ structurally?

4. Ethanol burns. CO2 and H2O do not. What does this tell you about the energy extraction efficiencies of fermentation vs. oxidative phosphorylation?
