Sodium ions bond with chlorine ions to form table salt, NaCl. Why does one sodium ion bond with one chlorine ion?
And of course, in an ionic solid (say $"sodium chloride"$), an isolated cation, a sodium ion, is BOUND ELECTROSTATICALLY to EVERY OTHER CHLORIDE ANION in the lattice. The attraction/repulsion follows...

Potassium has a mass of 39.1 amu. Chloride has a mass of 35.45 amu. By the law of conservation of mass, what is the mass of potassium chloride, when these two ions combine?
Since the formula for potassium chloride is $"KCl"$, add the atomic masses of potassium and chlorine to determine the atomic mass of $"KCl"$. $"Atomic mass KCl"="39.1 u + 35.45 u"="74.6...

I need some help understanding how some ions have the same electronic arrangement as noble gasses? Like why does a Li+ ion has the same electron structure as helium or a Mg2+ ion has the same electron structure
as a Na+ ion and an O2- ion?
A completely filled outer electron shell is stable because it can not gain any more electrons, it is full. Being completely full it has no desire to lose electrons thereby...

How do you write "Iron (III) chloride plus aluminum yields aluminum chloride and iron" in a chemical equation?
You don't need to note charges in the equation, if that's what you meant. The charge is implied because of the three Chlorides. Hope this helps!

How would you balance the following equation:
aluminum iodide and chlorine gas react to form aluminum chloride and
iodine gas?
Aluminum has a common oxidation state of $"3+"$, and that of iodine is $"1-"$. So, three iodides can bond with one aluminum. You get $"AlI"_3$. For similar reasons, aluminum chloride...

When magnesium ions form compounds with bromide ions, how many magnesium ion(s) are needed to form a neutral compound?
and bromine forms a $Br^(-)$ ion........... And so, if these ions are to make music together, and form a NEUTRAL ionic solid, we need 2 equiv of anion, and 1...

How many chloride ions are there in 4.50 mol of aluminum chloride?
So $4.50$ mol $AlCl_3harr3xx4.50=13.50$ mol $Cl^-$ 1 mol contains $~~6.02xx10^23$ particles, so the answer is: $n_(Cl^-)=13.50xx6.02xx10^23=81.27xx10^23~~8.13xx10^24$ (rounded to 3 significant digit because of the $4.50$)

How many molecules of chlorine gas would be produced if 10.0g of aluminum chloride decomposed into aluminum precipitate and chlorine gas?
First you need to write the correct BALANCED chemical reaction equation. Then you can determine how many moles of $Cl_2$ would be produced from the available moles of Cl in...

Aluminum oxide is decomposed to extract pure aluminum from the mineral. If 6.7 tons of aluminum oxide is mined, calculate the mass of pure aluminum produced?
1 mole of aluminum oxide has a molecular weight of 102 grams (Al=27 grams and O=16 grams). It means that for 1000 kg of compound you can get 529 kilograms...

Aluminum reacts with excess hydrochloric acid to form aqueous aluminum chloride and 46.5 mL of hydrogen gas over water at 27 degrees Celsius and 751 mmHg. How many grams of aluminum reacted? The partial pressure of water at 27 C is 26.8 mmHg.
We're asked to find the number of grams of $"Al"$ that reacted, given some $"H"_2 (g)$ product characteristics. Let's first write the chemical equation for this reaction: $2"Al"(s) +...
