Dafna1 [17]2 years ago
4 0

Answer:

Explanation:

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon

dioxide as shown below.

CaCO3(s) = CaO(s) + CO2(g)

The Kp for this reaction is 1.16 at 800°C. A 5.00 L vessel containing 10.0 g of CaCO3(s)

was evacuated to remove the air, sealed, and then heated to 800°C. Ignoring the volume

occupied by the solid, what will overall mass percent of carbon in the solid once equilibrium is reached?

Answer:

From least polar covalent to most polar covalent;

S-I< Br-Cl < N-H< Te-O

From most ionic to least ionic

Cs-F> Sr-Cl> Li- N> Al-O

Explanation:

Electro negativity refers to the ability of an atom in a bond to attract the shared electrons of the bond towards itself.

Electro negativity difference between two atoms is a key player in the nature of bond that exists between any two atoms. A large difference in electron negativity leads to an ionic bond while an intermediate difference in electro negativity leads to a polar covalent bond.

Based on electro negativity differences, the bonds in the answer have been arranged in order of increasing polar covalent nature or decreasing ionic nature.
