Question

which compound is most likely to be held together by a covalent bond based on the electronegativity difference between its two atoms?
A- CO
B- CaBr
C- NO
D- NaCl

Answer 1

Answer:

see below

Explanation:

1. combustion

2. The breakdown of hydrogen bromide is endothermic, and the formation of hydrogen iodide is exothermic.

3. the water

4. H–H

5.  It is endothermic because more energy is needed to break up the reactants versus the amount given off by the products.

6. NO

7. H–F

8. sunlight warming a concrete sidewalk

9. The total energy of the system will stay the same as kinetic energy from the warm water increases the kinetic energy of molecules in the ice

10. This is an exothermic reaction because the reactants have more energy than the products.

11. the energy that must be added to a system to break the bonds of the reactants

12. The activation energy required for manganese dioxide to form intermediate molecules with H2O2 is less than the activation energy required for H2O2 to decompose on its own.

13. written response

14. written response

15.  written response

16. written response

Answer 2

The compound most likely to be held together by a covalent bond based on the electronegativity difference between its two atoms is NO because it has the smallest electronegativity difference.

Which of the given compounds is most likely to be held together by a covalent bond based on the electronegativity difference between its two atoms?

Electrovalent or ionic compounds are formed between atoms whose electronegativities differences are far apart, usually between metals and non-metals.

Covalent compounds are compounds formed between elements with very close or similar electronegativities.

Covalent compounds have small electronegativity difference.

From, the given compounds, rhe compound NO has the smallest electronegativity difference.

Therefore, the compound most likely to be held together by a covalent bond based on the electronegativity difference between its two atoms is NO.
