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:
208 g/mol and 87 g/mol
Explanation:
Number of protons = 82
Atomic mass = 126 + 82 = 208 g/mol
For ^{87}Sr
Number of neutrons = 49
Number of protons = 38
Atomic Mass = 49 + 38 = 87 g/mol
