Hello,
I'd like to introduce you to the magnet analogy:
-Opposite sides attract
-Same sides repel
The first part applies to chemistry, so positive hydrogen bonds tend to attract to negative adjacent molecules.
Answer : b. mixture
<h3>Further explanation</h3>
Element and compound are included in pure substance where the composition is the same in each part
Elements are made up of 1 type of atom, while the compounds of 2 or more types of atoms
, both can be represented in the form of chemical symbols
A mixture is a combination of substances. The properties of a substance in the mixture component are unchanged
The mixture can be a homogeneous mixture or a heterogeneous mixture
- the homogeneous mixture if each part has the same composition
- the heterogeneous mixture if each part has a different composition
Solution including into Homogeneous mixture, while suspension into a heterogeneous mixture
So a term that could refer to heterogeneous matter : b. mixture
Pb(NO₃)₂(aq) + 2NaI(aq) → 2NaNO₃(aq) + PbI₂(s)
PbI₂ (the precipitate)
