Science & Technology Quiz 2: The one with the catchy title.

[Simple Simon]

You're using too much salt. That's going to taste horrible, surely?

2 TBSP salt, juice of two lemons, 4 TBSP brown sugar, some ground pepper, 8 TBSP olive oil. Wonderful!

We need ElJusto here, he'd pick up ASAP what you all are missing

Question for the Questioner:

Does it matter if the lemon juice is squeezed fresh from a lemon or not?

nope! The lemon is innocent, and will get a verdict of 'not guilty' with regards to the question WHY there is gas at all. Although the acid obviously causes the reaction.

 

[Mise]

I'm assuming that, since it's brown sugar, you haven't mixed up the salt with the sugar?

I pour the juice into a bowl, add the salt

The sugar's still in the cupboard. But you're on the right track - partly.

 

[Mise]

Some sort of additive in table salt??? Like, some chemical that makes it easily sprinkled??? (rather than crystalised or w/e)

now you need only name it.......
what substance is benign, can be ground finely (and thus have a very large surface per volume) and is (then) hygroscopic enough to keep salt (and sugar) from clumping - and happens to react strongly exothermic with acids, creating CO2?

 

[Mise]

Something something carbonate

...no idea what would satisfy the other requirements though... Ca- or Mg CO3 are pretty much the only "acid/carbonate" reactions I remember from school, and I don't think either were particularly exothermic?
EDIT: Oh wait it needn't even be a Group 2 metal...

What do you have against CaCO3? The reaction is exothermic enough that I have twice burnt my fingers when accidentally touching a metal plate that was mostly immersed in a bath of hydrochloric acid in which a block of limestone was submersed. Not badly, but I did get a red spot on my hand.

Interestingly, the use of ground chalk in salt and sugar is not mentioned on wikipedia

unless I am now too tired to find it.

The package says 'up to 7%', btw.

Perhaps the rest of us use real salt in our cooking.

 

[Simple Simon]

Perhaps the rest of us use real salt in our cooking.

unless you use large-crystal 'sea salt', there will be a substance in it that keep it from clumping. And there is a high chance that that substance is CaCo3.

Mise has it!

Open floor!

 

[nonconformist]

Why is Mise blue?

 

[Veritass]

Why is Mise blue?

Those are Smurfs, not mice.

 

[Mise]

Do I look blue to you????

 

[Perfection]

You have inverted qualia?

 

[nonconformist]

Nah, it's actually cos i'm strangling him to death with my thighs during an extended period of sexual passion.

Open floor.

Question:

What is RSA?...
On what principle does it work, and why is it in danger?

 

[Aramazd]

RSA is an algorithm used for public key encryption, but I don't think it's in danger.

 

[member66170]

It works on the principle of a 'trap door function'. Ie, its very easy to multiply two large primes together, but very hard to factorise a very long number.
Quantum computers, could break them in a matter of hours if not minutes if one with a reasonable amount of qubits could be built.
