Why is it important to use chemicals of high quality (purity) and exact(correct) concentrations in experiments?​
Darya [45]

It is important to use chemicals of high quality and correct concentrations in experiment so that we can obtain the predictable result in an experiment

Purity of substances/chemicals is very important when performing experiments in the laboratories, because it plays an important role in the determination of the chemical properties of  substances which will have a direct effect on the result obtained from the experiment. likewise using the correct concentration of reagents

During experiments to obtain the best/predictable result in an experiment it is of best practice to make use of chemicals of high quality and also at the exact(needed) concentrations, that way the predictable result of the experiment will be obtained.

The electronic configuration of an element is given below.
Amiraneli [1.4K]

 The statement  which  is true  about  the reactivity  of  element  with          1S²2S²2P⁶3S¹   is

 it is reactive   because it has to lose one  electron  to have  a full  outermost  energy  level.

<u><em>Explanation</em></u>

  • <u><em> </em></u>Element  with     1S²2S²2P⁶3S¹  electron configuration  is    a sodium  metal.
  •    sodium  has  one  electron  in the outermost energy level.
  • for  sodium to have  a full  outermost  energy level (  8 electrons) it   loses  the  1  electron   in 3S¹ to  form   a positively  charged ion. (Na⁺)
