Answer: Fe - O


Explanation:


1) Start by showing the chart information in a more understandable way:


Elements ---------- Electronegativity


aluminum (Al) ----- 1.61


calcium (Ca) ------- 1


carbon (C) ---------- 2.55


chlorine (Cl) -------- 3.16


fluorine (F) --------- 4


hydrogen (H) ------ 2.2


iron (Fe) ------------- 1.83


nitrogen (N) --------- 3.04


oxygen (O) ----------- 3.44


phosphorus (P) ----- 2.19


potassium (K) -------- 0.82


silicon (Si) ------------- 1.9


sulfur (S) --------------- 2.58


2) Find the electronegativity differences for the atoms in each compound:


i) Ca – Cl: 3.16 - 1 = 2.16


ii) Fe – O: 3.44 - 1.83 = 1.61


iii) H – S: 2.58 - 2.2 = 0.38


iii= F – F = 4 - 4 = 0


3) Analysis


i) The higher the electronegativity difference between two non-metal elements, the the more the polar the covalent bond. Therefore, the bond H - S is the most polar among the non-metal - non-metal bonds listed. But 0.38 is a small difference, so this is not very polar.


ii) For metal - non-metal bonds, when the difference in electronegativities is too high (close to or greater than 2.0) the ionic character is dominant, and so you cannot classify the bond as polar but as ionic. Therefore, Ca - Cl with 2.16 electronegativity difference is a ionic bond.


iii) The bond in Fe – O has electronegativty difference of 1.61, so it is yet covalent, and highly polar.

Answer:

The highest difference is in between N and H thus this will have greatest polarity.

Explanation:

More the electro-negativity between any two elements more the polarity in the bond. Electron negativity is the tendency to pull shared pair of electrons towards it self. If the difference between two bonded elements is way too high then it may result in complete transfer of electrons from the less electronegative element to more electronegative one. Thus the bond will be ionic and highly polar.

Among given options,the electro negativity differences are:

A) Al-Si : 1.9-1.61=  0.29

B) S-Cl : 3.16- 2.58 = 0.58

C) N-H : 3.04 - 2.2 = 0.84

D) C-N : 3.04-2.55 = 0.49

The highest difference is in between N and H thus this will have greatest polarity.

Examine the equation.
Alisiya [41]

Explanation:

The reaction expression is given as;

                 2H₂_{g}   +  O₂_{g}   →   2H₂O_{l}

From the balance reaction expression:

 2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;

This produces 2 mole of water on the product side of the expression.

The product is in liquid form.

 This reaction is a synthesis reaction because a single product is formed from two reactants.
