Answer:

See explanation

Explanation:

The bonding in certain compounds or ions can not be thoroughly explained in terms of a single Lewis structure.

The observed properties of the compound or ion indicate that it can not be entirely represented by a single Lewis structure. For example, all C-C bond in benzene are equal.

When this is the case, a number of structures called resonance structures are invoked in order to satisfactorily explain the properties of the particular chemical specie under study.

46. True or false. Chemical reactions do not involve changes in the chemical bonds that join

Naddika [18.5K]

Answer:

Chemical reactions do not involve changes in the chemical bonds that join

atoms in compounds :

False

Explanation:

Chemical reaction are the reaction in which old bonds break and new bonds are formed . The formation of new bond result in formation of new compounds . This happen because new bond are result of linking different atoms by the bond.

For example : Water formation from Oxygen and Hydrogen is a chemical process :

$2H_{2}+O_{2}\rightarrow 2H_{2}O$

Original(old) bonds are :

H-H bond in H2 and O-O bonds in O2

In H2 = Hydrogen is joined to Hydrogen

IN O2 = Oxygen is joined to oxygen

New Bonds =

O-H bonds in water (H2O)

Oxygen is joined to hydrogen = New Bond formation

Hence,

Chemical reactions do involve changes in the chemical bonds that join

A certain gas is present in a 13.0 l cylinder at 4.0 atm pressure. if the pressure is increased to 8.0 atm , the volume of the g

ella [17]

Boyle's Law is k = PV so Initial k = 13.0 L x 4.0 atm = 52 L atm Final kf = 6.5 L x 8 atm = 52 L atm The gas obeys Boyle's Law The answer with two significant figures separated by a comma is k = 52, kf = 52.

Which of the following elements has 3 electrons in the outermost d orbital?

Nina [5.8K]

Answer:

Explanation:

Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.

Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.

Valency of A⟶+3

Valency of B⟶−2

(Refer to Image)

Cross multiply valency of A and B

∴A2B3 compound will be formed.
