This is the chemical formula for carvone (the chemical that gives spearmint its flavor): An organic chemist has determined by me

xz_007 [3.2K]

The given question is incomplete. The complete question is :

This is the chemical formula for carvone (the chemical that gives spearmint its flavor) $C_{10}H_{14}O$ : An organic chemist has determined by measurements that there are 27.3 moles of carbon in a sample of carvone. How many moles of oxygen are in the sample

Answer: 2.73 moles of oxygen are there in the sample.

Explanation:

The chemical formula of carvone is $C_{10}H_{14}O$ .

This means:

When 10 moles of carbon are there in carvone , 1 mole of oxygen is there in carvone

Thus for 27.3 moles of carbon in carvone , $\frac{1}{10}\times 27.3=2.73$ mole of oxygen is there in carvone.

Thus 2.73 moles of oxygen are there in the sample.

_____ bonds are formed when the electronegativity difference is 0.4 > 2.0. Give two examples:

34kurt

Ionic Bond is formed when the electronegativity difference is 0.4 > 2.0. Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

Explanation:

Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

An electronegativity of an atom is affected by

The atomic number of the atom
Secondly by the distance at which the valence electron are residing from the nucleus

1. In case the electronegativity difference (which is denoted by ΔEN) is less than 0.5 then the bond formed is known as Nonpolar covalent.

2. In case the ΔEN is in between 0.5 and 1.6, the bond formed is referred to as the Polar covalent

3. In case the ΔEN is more /greater than 2.0, then the bond formed is referred to as Ionic Bond

2 Examples of Ionic bonds

The formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom is an example of Ionic bond formation.
Another example is the formation of NaCl from sodium (Na),which is a metal, and chloride (Cl), which is a nonmetal
