Answer : Option B) Attempt to control the conditions.
Explanation : While conducting an experiment, a scientist should always attempt to control the reaction conditions.
If the reaction conditions are not controlled one can lose the expected result or observation that was supposed to be generated from the experiment. Like controlling the given temperature, pressure, addition of catalysts, etc. If these conditions are overlooked one may not achieve the expected results and will not reach to the conclusion.
Answer:
Explanation:
The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes - because if there is much more of one isotope then that will influence the average mass much more than the less abundant isotope will.
M(Fe)=55.85 g
m(Cl)=106.5 g
M(Fe)=55.85 g/mol
M(Cl)=35.45 g/mol
n(Fe)=m(Fe)/M(Fe)
n(Fe)=55.85/55.85=1
n(Cl)=m(Cl)/M(Cl)
n(Cl)=106.5/35.45=3
FeCl₃ is the most likely empirical formula
