Which of the following pairs of elements is most likely to form an ionic bond? Sulfur and Oxygen Carbon and Chlorine Phosphorous
djverab [1.8K]

“<u>Aluminum</u>” and “<u>Nitrogen</u>” form an ionic bond.

Option: D

<u>Explanation</u>:

Aluminum and nitrogen are most likely to form an “ionic bond” among given pairs of elements in form of aluminum nitride. AlN is partially covalent and also show ionic characteristics as N needs 3 electrons to fill outer shell and Al has 3 electrons in valence shell. Hence \mathrm{Al}^{+3} is cation and \mathrm{N}^{-3} is anion and have “electrostatic force” of attraction between these oppositely charged ions. Here ionic behavior is seen as nitrogen is more “electronegative” hence attract the shared pair of electrons which is earlier responsible for partial covalent bond formation.

How can the law of conservation of<br> mass for a chemical reaction be expressed?
djverab [1.8K]

Answer:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Explanation:

How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.

can someone help me with my qustions?
