Answer:
Synthesis
Explanation:
Chemical equation:
3S + 2Fe → Fe₂S₃
The solid iron react with solid sulfur and form iron(III) sulfide. The reaction type is synthesis because,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
Other options are incorrect because,
In double displacement two compound exchange their ions and form new compounds.
AB + CD → AC +BD
In decomposition one reactant is break down into two or more product.
AB → A + B
In single replacement one elements replace the other element in compound.
AB + C → AC + B
A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups. In building a tree, we organize species into nested groups based on shared derived traits (traits different from those of the group's ancestor).
Iron, but there are some amounts of other dense elements like gold, platinum, and uranium.
Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>
