The two forms of oxygen, O2 and O3 is "<span>They have different molecular structures and different properties."</span>
harkovskaia [24]3 years ago
4 0

Answer: Option (4) is the correct answer.

Explanation:

In an O_{2} molecule there are two oxygen atoms and in a O_{3} molecule there are three oxygen atoms.

So, there will be different number of electrons involved in the bonding of atoms for both O_{2} and O_{3} molecules.

Therefore, both of them will have different structure and reactivity.

Thus, we can conclude that the statement they have different molecular structures and different properties, correctly describes two forms of oxygen, O2 and O3.

Write a net ionic equation to show how codeine, c18h21o3n, behaves as a base in water.
Lera25 [3.4K]

Actually, the ionic equation for this is a reversible equation since codeine is a weak base. Any weak base or weak acids do not completely dissociate which makes them a reversible process. The ionic equation for this case is:

<span>C18H21O3N  +  H3O+  </span><=> C18H21O3NH+ +  H2O

PLS HELP WILL GIVE BRAINLIEST
boyakko [2]

Answer:

The IUPAC structure only shows bond pairs and lone pairs. In the flouromethane structure above, there is only one bond pair and three lone pairs of electrons. Therefore there is one electron remaining, but since it doesn't not make up a pair, it is ignored in the structure but theoretically it is present.

To make a 6.50M solution, how many moles of solute will be needed if 12.0 liters of solution are required
avanturin [10]

Answer:

78 moles of the solute

Explanation:

From the question;

  • Molarity of the solution is 6.50 M
  • Volume of the solution is 12.0 L

We want to determine the number of moles needed

We need to know that;

Molarity = Number of moles ÷ Volume

Therefore;

Number of moles = Molarity × Volume

Hence;

Number of moles = 6.50 M × 12.0 L

                             = 78 moles

Thus, the moles of the solute needed is 78 moles
