Sodium chloride conducts electricity when dissolved in water. what type of bond is present in Nacl?
How Nacl is formed ?
Answer :-
Na is a metal, the electronic configuration of sodium (Na) = 2,8, 1 to complete octet and become stable sodium needs to collect 7 electrons from other element to full fill its outer most shell i.e its third shell or 'M' shell to get its nearest noble gas Argon (2,8,8) and to full fil octet and become stable or Na has to give up its only valence shell electron (1) to get 2,8 electronic configuration of Neon as sodium is a metal so according to metals chemical property , all metals give up electrons they do not accept electrons or they are unable to accept electrons due to strong inter molecular force, thats why sodium is also unable to accept 7 electrons.

So— back to the speculative evolution request list!
@thebigdeepcheatsy requested a "cactus-dwelling/germinating evolution of introduced rosy-faced lovebirds":
While Agapornis cheatsyi is still quite physically similar to its introduced ancestors, this lovebird has developed a close symbiotic relationship with the cactus Carnegiea ornipolis, a descendant of the modern saguaro.
Naturally fasciated, this cactus grows a splaying fan-like crown which the lovebirds excavate their shallow nest burrows into. Feeding on the cactus' fruit in early summer, the lovebirds then disperse the seeds via their droppings – a process that significantly improves propagation chances, both due to the birds commonly foraging and defecating around suitable nurse plants and the passage through their gut speeding up germination.

Someone calling themself "LB" asked for some "flying afrotherians":
Elbeitandraka venenifer is a descendant of tree-climbing Malagasy tenrecs that developed gliding membranes – and its lineage is now just about achieving true powered flight.
About 25cm long (~10"), its proportionally short broad wings require it to fly very fast to generate enough lift for its weight. It mostly only actively flies when traveling between roosts and feeding sites (or when escaping from threats), alternating between gliding to save energy and flapping to recover altitude.
It's an opportunistic omnivore, crawling around in the tree canopy foraging for vegetation, fruits, fungi, invertebrates, and the occasional smaller vertebrate, using its flexible sengi-like nose to probe around in crevices.
Much like modern common tenrecs it's capable of hibernating for months at a time through periods of scarce food availability. It also accumulates alkaloid toxins in its body from its arthropod prey, advertising its unpalatability to predators with bold contrasting warning coloration on its wing membranes.

And here's a combination of a couple of anonymous requests for both "flying heterodontosaurs" and "dragons with hind leg wings, a la sharovipteryx":
Inversodraco rapax is a highly specialized Jurassic descendant of heterodontosaurids that took to climbing and gliding, developing delta-wing-like membranes on their hindlimbs convergently similar to those of the earlier sharovipterygids.
Around 75cm long (~2'6"), it has unusually flexible hip joints for a dinosaur, able to splay its legs out to the sides to deploy wings supported by an elongated outer toe on each foot. Its arms form small forewings for stability, and its long tail ends in a vane of stiffened feathers that aid in steering.
Unlike its herbivorous-to-omnivorous ancestors it's primarily a carnivore, swooping down onto small prey and grabbing it with its talon-like forelimbs.
@strangersteddierthings this is for you. (There will be more, but I have stuff to do for Environmental Science homework, and need to post something about it, so that I can’t decide to give up abandon this—so I guess this is part 1/???)

Honestly, Eddie wasn’t sure where he went wrong. One minute, he was sitting with Steve, watching some movie that Steve had been far too excited to show him, and then next minute he was walking home. Alone.
It had been his fault, really, and he knew it.
He had kissed Steve Harrington. He had kissed Steve Harrington. What the actual fuck had he done?
There was something in him that jumped at the chance to make a real move once Steve had said he also liked men, and something in him that wanted to curl up and die on the spot because that just made this whole situation worse. Because he liked guys, but he didn’t like Eddie, and that was all too apparent when Steve’s face went from nervous to startled, frozen in place as Eddie instantly regretted everything.
“Is this a joke to you?” Steve had whispered, his voice sounding broken, tears in his eyes as he stood up and looked over at Eddie, arms crossed over chest like he was trying to hide himself—slumped over like he wanted to disappear.
“Steve—“
“I—I’m being serious! I mean it, Eddie…do—do you know how hard this is to say? How much it hurts to admit?” Steve shook his head slightly, his eyebrows pinched together, and Eddie wanted to explain everything, but he couldn’t. He was stuck, frozen in place on the couch, wanting so badly to tell Steve what he meant—what he wanted.
But he was walking home alone. The air was cold, and it felt even colder since he had left in a hurry, excusing himself before Steve would’ve started crying, because it hurt to see him like that, so scared and devastated—like he thought Eddie was going to tell everyone. And he wasn’t. Of course he wasn’t! He would never do that—but Steve didn’t know that.
So he had left his coat, only in a t-shirt and jeans.
He was going to have to go back and get it eventually. He knew that. But he didn’t want to face Steve—to have to admit why he did what he had, and how it wasn’t a joke to him—it was never a joke. It was just easier to ignore him than to face the truth and have to tell him.
The one thing nobody ever talked about enough was how painful feelings could be.
EDIT: there are more parts, and it is finished (maybe I don’t know if I’ll expand on this in the future)!
part 2, part 3, part 4
Can I see more highschool au fics where Kenny is the same kinda guy we usually see but also crazy academic smart and maybe taking advanced science classes bc like?? I never see that in fics even though he quite literallly becomes a billionaire scientist?? pretty please
If an external force is applied on a rigid body which is at rest and the point of contact of the force displaces i.e;if the body changes its state of rest and occurs a displacement, then in science it is called work done or work has been done. It is denoted by W. The C.G.S unit of work is erg and its S.I unit is Joule.
Mathematically,
work or work done = F× D
where, F= Applied external force.
and D = Distance/Displacement of the body.
Fireproof Super-Material Made From Household Items...
Starlite was a material invented in the 1960s that allegedly withstood 10,000°C temperatures.
Here, NighthawkInLight shows his copycat of the secret recipe, withstanding a still whopping 2000°C at less than 1" thickness.
The way it works: when exposed to high temperatures, it expands, creating a carbon foam barrier that pushes the heat away while forming an insulator.
The Recipe: 👇
2 parts Flour
1 part Corn Starch
1 part powdered Sugar
1 part Borax
1.5 parts Water
When mixed and formed and let dry, you have a fireproof tile with heat resistance claimed to be on par with alumino fire brick, while protecting against both insects and mold. 🤔
