across a period, how does the electronegativity of a nonmetal affect the acidity of its binary hydride
goblinko [34]
1) Across the period as one moves from left to right, atomic size decreases.

2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.

3) Here, atomic radius of these elements are in following order Si>P>S>Cl.

4) However, electronegative of these elements increases as we move from left to right

5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.

6) Due to this, bond polarity increases from left to right,

7) Increase in bond polarity, results in increasing proton donating capability.

8) Therefore, acidity increases as one moves along the period.

Solid Iron (III) reacts with oxygen gas to form iron (III) oxide, which is the compound we see when rust is present. Based on th
Sunny_sXe [5.5K]

Answer:

Option E is correct. none of the above is correct

Explanation:

Step 1: Data given

Solid Iron (III) = Fe^3+

iron (III) oxide = Fe2O3

Molar mass Fe = 55.845 g/mol

Molar mass Fe2O3 = 159.69 g/mol

Step 2: The balanced equation:

4Fe + 3O2 → 2Fe2O3

4 moles of iron will need 2 moles of oxygen gas to fully react

⇒ This is false 4 moles of iron will need 3 moles of oxygen gas to fully react

B.12 moles of iron, if reacted completely, can produce 8 moles of iron (III) oxide.

⇒ This is false: When 12 moles of iron completely react, we can produce 12/2 = 6 moles of Fe2O3

C.9 moles of oxygen can produce 9 moles of Iron (III) oxide

⇒ This is false; 9 moles of O2 can produce 6 moles of Fe2O3

D.6 moles of oxygen can react completely to produce 6 moles of iron (III) oxide.

⇒ This is false 6 moles of O2 will react completely to produce 4 moles of Fe2O3

E.none of the above

The electron configuration of an element is shown below.
gayaneshka [121]

Answer:it is in group 7

Explanation:it is in this group because in the increasing number of atomic number the element is found in group seven. The element is likely to receive 3 electrons while bonding with another element to make it stable.
