What is the best name for the following compound? CCl4
Nitella [24]

Answer:

The answer is b. Carbon Tetrachloride

Explanation:

Let's discard the other options:

a. It couldn't be carbon chloride because there are four (4) chloride ions in the molecular formula. The molecular formula for the carbon chloride must be CCI. So, this answer is wrong

c. It could be monocarbon tetrachloride because there are 4 chloride ions and 1 carbon ion, but it's not necessary to use the prefix "mono" because there is just one carbon ion in the formula. In that way, when we mention carbon in the name, there is implicit that there is just one carbon atom in the formula. So, this answer could be ok, but isn't the best.

d. It couldn't be calcium chloride because there isn't any calcium ion or atom in the formula. The molecular formula for the calcium chloride must be CaCI. So, this answer is wrong

An unknown concentration of sodium thiosulfate, Na2S2O3, is used to titrate a standardized solution of KIO3 with excess KI prese
Maru [420]

Answer: The molarity of Na_2S_2O_3 is 0.108 M

Explanation:

KIO_3+5KI+3H_2SO_4\rightarrow 3K_2SO_4+3H_2O+3I_2

2Na_2S_2O_3+I_2\rightarrow Na_2S_4O_6+2NaI

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}    

\text{Moles of }KIO_3=\frac{0.0131mol/L\times 21.55}{1000}=2.8\times 10^{-4}mol

1 mole of KIO_3  produces = 3 moles of   I_2

2.8\times 10^{-4} moles of KIO_3 produces = \frac{3}{1}\times 2.8\times 10^{-4}=8.4\times 10^{-4} moles of I_2  

Now 1 mole of I_2 uses = 2 moles of Na_2S_2O_3

8.4\times 10^{-4} moles of I_2 uses =  \frac{2}{1}\times 8.4\times 10^{-4}=1.69\times 10^{-3}  moles of Na_2S_2O_3

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution in L}}=\frac{1.69\times 10^{-3}\times 1000}{15.65}=0.108M

The molarity of Na_2S_2O_3 is 0.108 M
