is just another number, admittedly it is a very large number, $N_A=6.022xx10^23*mol^-1$. Let's do the problem by using $"dozens"$: $"1 dozen"="12 items of stuff"$.

$a.$ $"6 dozen S atoms"$ $-=$ $"72 sulfur atoms"$

$b.$ $"2 dozen"$ $S_8$ $"atoms"$ $-=$ $"192 sulfur atoms"$

$c.$ $"5 dozen"$ $SO_2$ $"molecules"$ $-=$ $"60 sulfur atoms"$ and $"120 oxygen atoms"$.

$d.$ $"2 dozen"$ $CO_2$ $"molecules"$ $-=$ $"24 carbon atoms"$ and $"48 oxygen atoms"$.

And the answer is clearly $b.$ Are you following me?

As liquid water freezes, the molecules arrange themselves in a way that takes up more space than llquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules?

If ice were denser than liquid water, icebergs would likely sink (even given that sea water is denser than normal water). If this were the case then oceans would likely...

Why do we not represent elemental sulfur as $S_8$?

We could write.......... $2H_2S(g) + SO_2(g) rarr 3/8S_8 +2H_2O$ for the $"comproportionation reaction"$. Is it balanced with respect to mass and charge? Don't trust my 'rithmetic. But sulfur is...

How do you balance $S_8 + O_2 -> SO_3$?

But because some might disagree with the use of a non-integral stoichiometric coefficient, we could use integral coefficients: $S_8(s) + 12O_2(g) rarr 8SO_3(g)$ Both reactions are formalisms. They do...

How do you balance $Ag_2S -> Ag + S_8$?

$Ag_2S -> Ag + S_8$ $8Ag_2S -> Ag + S_8$ Now, the Sulphur balances, but not the Ag ... $8Ag_2S -> 16Ag + S_8$ Balanced!

What is the balanced equation for $S_8+O_2->SO_2$?

Alternatively I could use a non-integral stoichiometric coefficient for sulfur: $1/8S_8(s) + O_2(g) rarr SO_2(g)$, or more simply, $S(s) + O_2(g) rarr SO_2(g)$ This form might make the arithmetic a...

Elemental sulfur occurs as octatomie molecules, $S_8$. What mass of fluorine gas is needed to react completely with 28.6 g of sulfur to form sulfar hexafluoride?

We need (i) a stoichiometric equation: $S(s) + 3F_2(g) rarr SF_6(g)$. And (ii) the molar equivalence of sulfur and fluorine $=$ $(28.6*g)/(32.06*g*mol^-1)$ $=$ $0.892*mol$. And thus $0.892xx3xx38.00*g*mol^-1$ $~=$ $100*g$...

Elemental sulfur occurs as octatomic molecules, $S_8$. What mass (g) of fluorine gas is needed to react completely with 17.8 grams of sulfur to form sulfur hexafluoride?

Start with a balanced equation. $"S"_8+"24F"_2$$rarr$$"8SF"_6"$ Then determine the molar masses of $"S"_8"$ and $"F"_2"$ by multiplying the subscript of each element by its from in g/mol. $"S"_8":$ $(8xx32.06 "g/mol")="256.48...

What is the maximum mass of $S_8$ that can be produced by combining 83.0 g of each reactant in the reaction $8SO_2 + 16H_2S -> 3S_8 + 16H_2O$??

The idea here is that you need to use the that exists between the two reactants to determine whether or not you're dealing with a . Start by...

How many molecules of each substance are present after the combustion of 3 molecules of propane with 10 molecules of oxygen?

This is a limiting reactant problem. Step 1. Write the balanced equation. $"C"_3"H"_8 + "5O"_2 → "3CO"_2 + "4H"_2"O"$ 2. Identify the limiting reactant One way to identify the...

If a substance has very polar molecules, will the attraction between its molecules be stronger or weaker than the attraction between a substance with nonpolar molecules?

If you have a substance with nonpolar molecules , the only that exist are London-Dispersion forces, which are very weak. However, if you have a substance with polar molecules, then...
