Given the following data:


2Mg + O2 → 2MgO DH = −1204


MgO + H2O → Mg(OH)2 DH = −37


2H2O → 2H2 + O2 DH = +572 kJ




Calculate DH for the reaction


Mg + H2 + O2 → Mg(OH)2

I have a no frost fridge with a freezer compartment. When I put water in the ice trays into the freezer they turn into ice after a couple of hours. If i do not use the ice for a couple of weeks, the ice starts to shrink and then it disapears from the ice tray, why? where does it go?

cells? is this forming of a cell a compound. Why do we need to take in oxygen atoms for ATP. Why is the sun and light given plants food Is light a atom it self and if so if it came in contect with antmatter would it be the same result with are matter. in theorys on dark matter or dark enrgy?

Hi. How hard is the vacuum over the mercury in a barometer. Unless the mercury goes into some level of vapor phase I would think it was nearly perfect.

I refer you to Chapter 4 of The Elegant Universe (but the experiments are in many references).
1. Figure 4.10 showing Feynman's 'every possible path' would seem to fall victim to astute philosophical scrutiny. If each photon could follow every possible path on the source side of the barrier then wouldn't all photons passing through the slits also be constrained to follow every possible path on the event side of the barrier (in any reducto ad adsurdum) and therefore yield no pattern at all? Due to random distribution wouldn't the pattern be that of a 'normal curve'?
2. Is it technically possible to conduct the experiment as shown in Figure 4.8 and have results meaningful on the quantum level considering reflection and refraction caused by the inside edges (the barrier must be thicker than a photon) of the slots on a quantum fluff level, much less considering the effects of the uncertainty principle and unpredictable nature of restricted particles?
Have these experiments been done?

We are doing an experiment in Biology about the best way to keep your hands germ free in a public bathroom and we heard that the blow dryers for your hands pick up the air from the (bacteria covered) floor and we have to reasurch this so it would be nice for some help.
