So, your metric isn't a good one, because it's massively distorted by the pattern of testing.

So a country like Zimbabwe is a success because it can not afford testing and no case will be confirmed. Don't worry, we will have plenty of time to test epidemiological models over the coming months.

Acetic acid, at concentrations high enough to affect the glue will really trash your skin.

You could powder them then sinter them. I have no idea why you would bother.

I'm willing to bet that water and alcohol each kill more. Both are vital in the fight against Covid But the point isn't "what kills most people?", its what "saves more people than it kills" to the greatest extent? If people have bleach, but not peroxide then telling them not to use bleach is a serious mistake.

Do you mean the sulfa drugs? A rather old group of anti bacterials? They are useful in some cases, but they are no use against a virus.

When I see a list with lead, arsenic and mercury on it, I don't immediately think they would be good for me. There are lots of things that wreck proteins- thos metals and bleach are good examples. I don't plan to drink bleach as an antiviral. I'm made of proteins too.

"Is this study linking phones to cancer reliable?" If it was, I'd expect to hear about it on the news headlines rather than a discussion forum.

Choline doesn't smell. But bacteria will convert it to trimethylamine which smells fishy. Rinse the containers with water. A bit of choline isn't going to cause much problem (even if you end up drinking it). As you note... It's hardly toxic.

It can be reduced, but not readily.

There would be nothing to stop you using water as the solvent for the acid and a different solvent for the base- as long as the solvents mix (and no awkward side reactions happen). Maybe glycerin or glycol would dissolve enough calcium hydroxide; they are certainly better solvents than water is.

Did anybody specify that the solvent is water? I must admit, I can't easily think of anything in which you could prepare a 4.69M solution of Ca(OH)2

I'm waiting for the anti gravity thing based on spinning magnets. And, of course, green ink.

Of course, you could always try joining an army. In some countries the pay is poor, but that does not matter because you are housed + fed. It's as if they are a bit... socialist.

Except people had hot meals and a roof before they had money. And most children don't have money but... And the world has plenty of food and enough buildings, yet some people are left cold and hungry because people think money is important.

Money is shiny bits of metal and pretty pictures on paper (or plastic film). It's not much of a motivator.

OK, so one of them is run by a mad dictator and.. Oh never mind.

That does not make sense. That is not true. That is a non sequitur.

In all sensible probability this is pointless. It's hypochlorite. We know this because...

Is there any actual evidence of a decline for which we need an explanation?

When a young man forgets his hat he says "I have forgotten my hat" When an old man forgets his hat he says "I am getting old". A set of pictures of someone fluffing their lines proves nothing (except that someone chose to put it together). What are Walker Bragman's political leanings?

The US has a bigger military expenditure than the next six or so countries put together. You certainly do not need that sort of excess to defend your homeland. So the question is ; why spend so much government money on it? And the answers are (among others) that: it provides employment. It provides a mechanism for giving education and training It provides a mechanism for research and development. Those are all fine socialist ideals. There's also a number of veterans' programs that also tick the box. It's also clear that many warriors (I think that's the term for army, airforce and naval operatives) are prepared to sacrifice their lives for the society in which they were raised. That's a much more concrete self-sacrifice than voting to pay higher tax rates to support the country's values. Now there's a bit of a glitch that some of the R&D is outsourced to private industry but, apart from the senior staff who get paid obscene amounts for very little risk or work, those companies' employees are practically speaking paid by the state too.

Na atom of Ca weighs more than an atom of Mg. So, a molecule of MgCO3 weighs less (84.3/100.1) than a molecule of CaCO3. I'd not call that a lot more CO2 per gram, but it's more. I suspect that on a dollar for dollar basis, CaCO3 is better.

We will no doubt find out if they do.
