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
Answer:
2.08 moles (3 s.f.)
Explanation:
number of moles
= number of atoms ÷ Avogadro's constant
Avogadro's constant= 6.022 ×10²³
Thus, number of moles
= 1.25×10²⁴ ÷ (6.022 ×10²³)
= 2.08 moles (3 s.f.)
