Answer:

Yes, a chemical change occurs.

Explanation:

CuSO_{4} + CaCl_{2} = CuCl_{2} + CaSO_{4}

CaSO4 is insoluble in the water, so a chemical reaction or chemical change occurs.

The compound IF5 contains Question 16 options: polar covalent bonds with partial negative charges on the F atoms. ionic bonds. p
larisa86 [58]

Answer:

See explanation

Explanation:

The molecule IF5 possesses five I-F polar bonds. However, the presence of polar bonds does not automatically imply that the molecule will be polar.

The geometry of the molecule is very important in determining the polarity of a compound. Since IF5 has a lone pair of electrons, the molecule is bent and as such there is a permanent dipole moment created in the molecule thereby making IF5 polar in nature.

What is the key principle behind VSEPR theory
PSYCHO15rus [73]

Answer:

Minimizing repulsion by maximizing the bond angles

Explanation:

VSEPR is defined as 'valence shell electron pair repulsion' theory. The key principle is that repulsion of adjacent lone pairs of electrons or the electrons that are shared within a bond creates bond angles.

The bond angles are maximized in order to minimize the repulsion in the most stable geometrical shape of the molecule.

That said, in VSEPR theory we tend to achieve the greatest possible angles between the bonds and lone pair electrons in order to obtain the lowest repulsion between them.

Atoms of one element easily changes to atoms of another element <br> a. True <br> b. False
Ganezh [65]
Hola!

→ Your query:
Atoms of one element easily changes to atoms of another element. Is it True? or False?

→ The answer is: TRUE

→ Reason :
We can change atom of one element to other atom by adding more particles into them. ex : Neutron, Protons and Electrons.

This is how nuclear fusion works. 

hope it helps!
