Which of the following pairs of elements would form the covalent bond with the largest dipole moment? View Available Hint(s) Whi

LekaFEV [45]

Answer:

In-F bond has the largest dipole moment.

Explanation:

Given the electronegativities:

Ge= 2.01

O= 3.44

H= 2.20

P= 2.19

In= 1.78

F= 3.98

B= 2.04

N= 3.04

The bond between Ge and O has an electronegativity difference:

ED= 3.44 - 2.01= 1.43

The bond between H and P has an electronegativity difference:

ED= 2.20 - 2.19= 0.01

The bond between In and F has an electronegativity difference:

ED= 3.98 - 1.78= 2.20

The bond between B and N has an electronegativity difference:

ED= 3.04 - 2.04= 1.00

As In-F bond has the largest electronegativity difference, this is the covalent bond with the largest dipole moment.

Part B When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 22.8 g of carbon were burned in the pres

aksik [14]

Answer: The amount of carbon dioxide gas produced in the reaction is 83.6 grams

Explanation:

As, some amount of oxygen gas is left after the reaction is completed. So, it is present in excess and is considered as an excess reagent.

Thus, carbon is considered as a limiting reagent because it limits the formation of product.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of carbon = 22.8 g

Molar mass of carbon = 12 g/mol

Putting values in equation 1, we get:

$\text{Moles of carbon}=\frac{22.8g}{12g/mol}=1.9mol$

The chemical equation for the reaction of carbon and oxygen gas follows:

$C+O_2\rightarrow CO_2$

By Stoichiometry of the reaction:

1 mole of carbon produces 1 mole of carbon dioxide gas

So, 1.9 moles of carbon will produce = $\frac{1}{1}\times 1.9=1.9moles$ of carbon dioxide gas

Now, calculating the mass of carbon dioxide from equation 1, we get:

Molar mass of carbon dioxide = 44 g/mol

Moles of carbon dioxide = 1.9 moles

Putting values in equation 1, we get:

$1.9mol=\frac{\text{Mass of carbon dioxide}}{44g/mol}\\\\\text{Mass of carbon dioxide}=(1.9mol\times 44g/mol)=83.6g$

Hence, the amount of carbon dioxide gas produced in the reaction is 83.6 grams
