Bleach is a terrible choice if you're just wanting a weak base, as it is highly reactive in its own right and can evolve poisonous gas (Cl2). A good weak base is something like baking soda, NaHCO3. That will fizz and evolve CO2 in contact with an acid, but all it does to what remains is to introduce some Na+ ions. What intrigues me about the reaction is the possibility of producing some elemental sulphur. That will be insoluble in aqueous solution so you should get some kind of yellow precipitate if you let it all settle.

I don't know the reactions of pyrite but found this paper: https://www.mdpi.com/1996-1944/15/12/4181/html which suggests the product of oxidation of pyrite with nitric acid may be FeSO4 and elemental sulphur: FeS2(s) + 8 HNO3(aq) → Fe2+(aq) + SO42−(aq) + S0(s) + 8 NO2(g) + 4 H2O(aq) But the way you are going about this is not very scientific - and not at all safe, as you have now found out. Why are you adding "bleach" and what is the chemistry of this bleach? Doing that is not going to help you determine what is in your yellow or reddish solution, is it? I think you need to weigh the quantities and calculate how much nitric acid to add, knowing its concentration, then test the resulting solution with pH paper before going any further. Then think about what else you might test for to see what is present. If you have excess acid and you start chucking in NaOH, or something nitric acid can decompose (like the hypochlorite often used in bleaches), you are asking for a trip to hospital. Eyesight is a precious thing. It's great you are having fun with chemistry but please take care. Test with small quantities, in vessels with wide necks (not a graduated cylinder), so any sudden evolution of gas or heat can escape and with plenty of ventilation or in the open air if you are trying this at home. Gloves, face protection and long sleeves strongly recommended, as you say.

Thanks. I think this makes sense. When you have the 100 ton boat floated with one ton of water, in a tight rigid container, it helps to consider the container itself. The boat does not "sense" any difference between the tight container and a vast pool of water of that depth. The displacement matters, not where that displaced water is, so long as the column is deep enough. And thanks for commiserations. Much better to have a divot than a bump. I'm going to fill it with water and see what I can float.

The physics is remarkably simple. It's only clouded by the meaning of the word "displace". The rock will float purely and simply when the pressure on it's lower surface reaches a certain level P. The pressure in the liquid is purely down to the depth D. If the rock is placed in an open pond, it will float when the bottom is at depth D. Explain how and why the pressure on the bottom is not exactly the same, at depth D, in a close fitting container as described.

I was under the impression that there is a religion section in this forum for discussing the scientific aspect of religion, not for expounding individual religous beliefs.

According to my reading, it seems the torsion pendulum was used to detect the thrust allegedly produced from this RF resonant cavity thingie. I recall that torsion pendulums have been used in determinations of big G, so are known to be capable of responding to very small forces. So now it makes sense - even if the physics doesn't........

I think it fundamentally answers the OP, any treatment for depression that doesn't involve medication has to be communicated and for that we need a common language and what better place to start; a smile may not be the answer (I seldom get angry with a smile on my face), but it is a step on the path...

No that's wrong. To lift the rock, you just need sufficient pressure on the bottom surface of the rock. In a tight fitting container, you can get that with a smaller amount of mercury. That should be obvious. It appears to contradict Archimedes principle, but it doesn't, because in the tight fitting container, the sunken part of the rock IS displacing the same weight of mercury as it would in an open system. Because it's occupying the same volume as it would in an open system with the same surface level.

But what does your conscience say?

At this realm of mankind that we do find ourselves in, to the extent that we can process rational thought, then it can be presupposed that it’s upon man in the usage of reason to know what constitutes the boundaries of that which is right and wrong hence act in accordance with that which is just, in order to maintain interpersonal relations that’re empathic to the next person. It’s in the context of the foregoing protocol of human relations, that institution’s’re built and norms of engagement’re established. As such, on the basis of the above, I can’t attribute to myself aspects that seem to be judgmental without according the other side, some space to be…to be to the extent that that leeway doesn’t interfere with my right to be; to think, to live to the best of my potential. Because by judging, do I start to infringe on the other’s rights by limiting their freedom to think and hence, express themselves. Unshackling you begins with me allowing you to think.
