Answer: scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis.
Explanation:
When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Double displacement reaction is defined as the reaction in which exchange of ions takes place.

When sodium permanganate reacts with iron (III) chloride, it leads to the production of sodium chloride and iron (III) permanganate.
The chemical equation for the reaction of sodium permanganate and iron (III) chloride follows:

By Stoichiometry of the reaction:
3 moles of aqueous solution of sodium permanganate reacts with 1 mole of aqueous solution of iron (III) chloride to produce 1 mole of solid iron permanganate and 3 moles of aqueous solution of sodium chloride
Hence, the balanced chemical equation is written above.
They include elements 57-71 (lanthanides) and 89-103 (actinides)
