Which type of bond is present in hydrogen sulfide (H2S)? The table of electronegativities is given
o-na [289]

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).

Is the genie in the bottle experiment a physical or chemical change/reaction?
gladu [14]

Answer:

Chemical reaction.

Step-by-step explanation:

In the experiment, a catalyst is added to concentrated hydrogen peroxide.

The hydrogen peroxide <em>decomposes</em> rapidly, according to the equation

2H₂O₂(ℓ) ⟶ 2H₂O(ℓ) + O₂(g)

New substances are formed, and old ones disappear, so this is a chemical reaction.

The reaction also releases a <em>large amount of heat</em>.

The rapidly-expanding oxygen gas caries with it droplets of water and hydrogen peroxide (and probably some steam, as well).

The visual effect is like a genie escaping from its bottl<em>e</em>.
