Bonds formed between atoms can be classified as ionic and covalent
Ionic bonds are formed between atoms that have a high difference in the electronegativity values.
In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds. If the atoms have very similar electronegativities, they form non-polar covalent bonds.
In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).
Answer:
I do not know the Answer I'm just trying to get my point
Explanation:
Thank you
Answer: The bond of molecule AB is then best described as a covalent bond
Explanation: The bond molecule AB is covalent because the difference in their electronegativity is not very big
#1 is 95L balanced . #2 is 55^3G balanced.
Answer:
D)Coat the disc with another pure substance, such as copper.
Explanation:
To make a mixture of the zinc, simply coat it with another pure substance such as copper. This will result in a mixture.
What then is a mixture?
- They are impure substances with indefinite composition.
- They retain their physical properties
- their constituents reacts differently to changed conditions
- They can easily be separated into constituents by physical methods.
We can see that coating the copper on the zinc does not alter the physical properties of the metal.
Most times, the copper will wear off and leave behind the zinc.
The metal coated can easily be removed and this signifies just a physical mix.
