Why lattice anergy is the key to the formation of salt?
Lattice energy is the energy given off when oppositely charged ions in the gas phase come together to form a solid. This process releases a great deal of energy. Table Lattice energy is the energy given off when oppositely charged ions in the gas phase come together to form a solid. This process releases a great deal of energy. Table salt is made up of chloride and sodium. The ions of each element bond together to create the compound know as salt, or sodium chloride. The opposite charges of the ions of each force the atoms together. The lattice energy is what causes the salt to crystallize when the two elements from the compound. The importance of lattice energy is that it prevents the compound NaCl (table salt) from being NaCl2, or NaCl3, etc salt is made up of chloride and sodium.

What is the cation for NaCl2?
NaCl2 does not exist. Perhaps you are referring to NaCl, in which case the cation is Na^+.
Why can't you have an atom of a compound?
Certain compounds won't form because the constituent atoms won't bond with each other to form it. The reasons for this basically fall into two groups. One is that the charges are not balanced. Table salt is sodium chloride, or NaCl, and we don't see Na2Cl or NaCl2 because the sodium has a +1 electronegativity, and chlorine has a -1 electronegativity. This means for charges to balance, they must combine one-to-one, two-to-two or the like. Sodium and chlorine basically only hook up one way. The other has to do with something a bit less obvious, but not too tough, and we see it here. The "final energy state" of NaCl is something the molecule is "happy" with. We don't see Na2Cl2 or the like. The atoms "decide" to hook up in a one-to-one ratio, and only one on one. Not two on two or something else, because the molecule moves to a lower energy state, and a more stable one, by combining in just that single way. One Na and one Cl yields one Na+ and one Cl- to make one salt molecule. The two atoms get together, and chlorine borrows sodium's lone valence electron making two ions, which are (ionically) bonded together. This latter "variable" that determines what will and will not combine can become extremely complex, particularly as we climb up through the elements in the periodic table. An example of an extension of the latter idea is the oxides of iron, which are all iron and oxygen (naturally). The conditions under which the oxide forms determine which ratio of the several possibilities will occur. (Iron has several electronegativities from 1 to 6.) This makes for interesting possibilities. And it's all about whether there is enough energy to form the compound, and to what energy level it can go to by "hooking up" to form that compound.
Chemical formula for alka-seltzer?
the ingridents r aspirin and pain reliefActually, the main ingredients of Alka-Seltzer tablets are aspirin, citric acid, and sodium bicarbonate (NaHCO3). But it's mostly sodium bicarbonate (or baking soda). I hope this helped. xox, Smartiiz
What is the limiting reactant reagent and what is excess reagent in recrystallization?
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.

What coefficients can be used to balance this epuation H2 NaCl2 NaH Cl?
First off, it is going to be NaCl, not NaCl2 and Cl2, not Cl. Secondly, the balanced equation would be H2 + 2NaCl -> 2NaH + Cl2
How many atoms does NaCl2 share?
No such substance as 'NaCl2'. However, NaCl (sodium chloride or common table salt) has two atoms viz. 1 x sodium(Na) and 1 x chlorine(Cl).
How many atoms of hydrogen are in are in sugar?
I know that table salt has no hydrogen atoms; NaCl2
What formula do you get if you mix NaCO3 and CaCl2?
It appears to be a metathesis (or double replacement reaction), so you would have NaCl2+CaCo3.
What is the reaction between bleach and potassium iodide?
the reaction between bleach anb potassium iodide is KI+NaCl2--->KCl2+NaI
How do you balance Na1Cl2?
Your question leads me to believe that you have the following equation: Na + Cl ---> NaCl2 In that case, note there is one Na (sodium) on the left and one on the right, so they are good. There's one chloride on the left but two on the right, so placing a "2" in FRONT of the Cl on the left will balance the equation and look as such: Na + 2Cl ---> NaCl2
What is the common name and uses of NaCl chemistry subjecct?
Its NaCl2, called sodium chloride, It is simply common table salt which is used with food.
