a 9.84 ounces ingot of unknown metal is heated from 73.2 degrees fahrenheit - 191.2 degrees fahrenheit this requires 3.912 calor

Answer:

The one above B

Explanation:

The one above B is most represents a compound because compounds are chemically bonded and are always near each other.

To calculate the charge of each atom.

Formal charge= Valence electrons-(non bonding electron+bonding electron/2)

The possible resonance of CNO- ( check attachment)

The second structure is the most stable because in this structure each atoms carry less formal charge than other.

(a) In the most stable resonance structure of CNO- leftmost bond is a triple bond.

Therefore the statement is False

(b) in the most stable resonance structure of CNO- rightmost bond is single.

Therefore the statement is true

(c) in the most stable resonance

structure of CNO- the formal charge on the leftmost is -1.

Therefore the statement is False

(d) in the most stable resonance structure of CNO-,the number of non bonding electron pairs on the leftmost carbon is 1.

Therefore the statement is False

(e) in the most stable resonance structure of CNO-the number of non bonding electron pairs on rightmost oxygen atom is 3.

Therefore the statement is False

Your answer is choice C. That is solid sodium chloride never dissolves to form sodium ions and chloride ions.

Going further to explain, have a look at the question again, we are told that James Proton prepares a saturated solution of sodium chloride in a beaker by adding solid sodium chloride and stirring.

Then when James finishes, crystals of sodium chloride are observed at the bottom of the beaker.

This implies that no more salt was dissolving since the saturation point was reached.

Again suppose he increased the temperature of the reaction, more salts could have dissolved.
