If 6.96 mol of C 5 H 12 reacts with excess O 2 , how many moles of CO 2 will be produced by the following combustion reaction? C

kati45 [8]

Answer:

34.8 moles of CO₂ are produced

Explanation:

This is the reaction:

1C₅H₁₂ + 8O₂ → 6H₂O + 5CO₂

Ratio is 1:5. We make a rule of three

1 mol of pentane can produce 5 moles of CO₂

Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles

What does index fossil mean?

marysya [2.9K]

An index fossil is a fossil that is useful for dating and correlating the strata in which it is found.

Or it is a fossil that helps you find the date where it has been found. I rephrased that.

DDT, an insecticide harmful to fish, birds, and humans, is produced by the following reaction. 2 C6H5Cl + C2HOCl3 → C14H9Cl5 + H

Elena-2011 [213]

Answer:

1,070.41 grams of DDT will be formed .Explanation:

1) $2 C_6H_5Cl + C_2HOCl_3\rightarrow C_{14}H_9Cl_5 + H_2O$

Moles of chlorobenzene = $\frac{1197 g}{112.5 g/mol}=10.64 mol$

According to reaction, 2 moles of chloro benzene reacts with 1 mole of chloral . Then 10.64 moles of chloro benzene will react with :

$\frac{1}{2}\times 10.64 mol=5.32 mole$ of chloral

2) Moles of chloral = $\frac{456 g}{147.5 g/mol}=3.0915 mol$

According to reaction, 1 moles of chloral reacts with 2 mole of chlorobenzene . Then 3.0915 moles of chloral will react with :

$\frac{2}{1}\times 3.0915 mol=6.1830 mol$ of chloro benzene

As we can see that chloral is in limiting amount and chloro benzene is in excessive amount. So, amount of DDT will depend upon amount of chloral.

According to reaction, 1 mole chloral gives 1 mole DDT.Then 3.0195 moles of chloral will give :

$\frac{1}{1}\times 3.0195 mol=3.0195 mol$

Mass of 3.0195 moles of DTT :

3.0195 mol × 354.5 g/mol = 1,070.41 g

1,070.41 grams of DDT will be formed .
