An average sample of chlorine contains 75.77% chlorine-35, with an atomic mass of 34.969 amu (atomic mass units), and 24.23% chlorine-37, with an atomic mass of 36.966 amu. What is the average atomic mass of chlorine?
The weighted average is the sum of each individual nuclide, multiplied by its isotopic abundance. So, we simply do the arithmetic: $0.7577xx34.969+0.2423xx36.966 = ???$ amu Then look at to...

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...

Chlorine gas, $Cl_2$, reacts with potassium bromide, $KBr$, to form potassium chloride and bromine, $Br_2$. How do you write the balanced equation for this single-displacement reaction?
Unbalanced Equation $"Cl"_2" + KBr"$$rarr$$"KCl" + "Br"_2"$ Balance the Cl There are 2 Cl atoms on the left side and 1 Cl atom on the right side. Add a coefficient...

Arsenic reacts with chlorine to form a chloride. If 1.587 g of arsenic reacts with 3.755 g of chlorine what is the empirical formula of the chloride?
$"Moles of arsenic"$ $=$ $(1.587*g)/(74.92*g*mol^-1)=0.0212*mol$. $"Moles of chlorine"$ $=$ $(3.755*g)/(35.45*g*mol^-1)=0.106*mol$. We divide thru by the lowest molar quantity to give $AsCl_5$. This is not chemical you would find in a...

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 reacts with aqueous $HBr$ to produce hydrogen gas and aluminum bromide. How many mL of hydrogen gas are produced at 1.03 atm and 20.00 $"^o$C when 0.498 g of aluminum react with an excess of $HBr$?
Each equiv of metal reduces $3$ equiv of acid, and $3/2$ equiv of dihydrogen gas are evolved. $"Moles of aluminum"$ $=$ $(0.498*g)/(26.98*g*mol^-1)=0.0185*mol$. Now, given the conditions, clearly the metal is...

A bottle of calcium bromide contains a bromide ion concentration of 0.10 mol/L. What is the concentration of the calcium bromide?
Calcium bromide speciates in aqueous solution according to the following equation......... $CaBr_2(s) stackrel(H_2O)rarrCa^(2+) + 2Br^-$ And thus for every metal ion there are necessarily two bromide ions. Here by...
