Answer:

C Hydrogen bonding is the main force that attracts water molecules to

one another.

Explanation:

Hydrogen bonding affects water molecules because, it is the main force which holds and attracts water molecules to one another.

Hydrogen bonding is an intermolecular force.
Intermolecular forces holds molecules together. Examples are van der waals forces, hydrogen bonding.
In a hydrogen bonding, hydrogen of one molecule electrostatically combines with a more electronegative specie usually nitrogen, flourine and oxygen on another atom.
This attraction results in hydrogen bonding between two or more molecules.
The unique and anomalous behavior of water is as a result of these hydrogen bonds between its molecules.

How to find electronegativity differences

lidiya [134]

To calculate electronegativity, start by going online to find an electronegativity table. You can then assess the quality of a bond between 2 atoms by looking up their electronegativities on the table and subtracting the smaller one from the larger one. If the difference is less than 0.5, the bond is nonpolar covalent.

when copper sulfide is partially roasted in air (reaction with o2), copper sulfite is formed first. subsequently, upon heating,

Lyrx [107]

The question is incomplete, complete question is:

When copper(I) sulfide is partially roasted in air (reaction with oxygen), copper(I) sulfite is formed first. subsequently, upon heating, the copper sulfite thermally decomposes to copper(I) oxide and sulfur dioxide. Write balanced chemical equations for these two reactions.

Answer:

The balanced chemical equations for these two reactions:

$2Cu_2S(s)+3O_2(g)\rightarrow 2Cu_2SO_3(s)$

$Cu_2SO_3(s)\overset{heat}\rightarrow Cu_2O(s)+SO_2(g)$

Explanation:

On partial roasting of copper sulfide in an air. The balanced chemical reaction is given as:

$2Cu_2S(s)+3O_2(g)\rightarrow 2Cu_2SO_3(s)$

On further heating of copper(I) sulfite it get decomposes into copper oxide and sulfur dioxide. The balanced chemical reaction is given as:

$Cu_2SO_3(s)\overset{heat}\rightarrow Cu_2O(s)+SO_2(g)$
