It is a separation tactic. Atoms of metalloids have about half of a complete set of electrons in their outer energy level
This problem is providing us with the width, 14.15 inches and height, 10.61 inches of a computer monitor, so the area of this display in square meters is required. At the end, the result turns out to be 0.09659 m².
<h3>Dimensional analysis:</h3>
In chemistry, we use dimensional analysis in order to figure out results given some numerical information; however, despite not having a specific formula for every problem, one can use the required units as a reference to come up with a convenient mathematical setup.
In this case, one can firstly calculate the area in square inches:
Next, we use the equivalence statement relating inches with meters, 1 in = 0.0254 m, to obtain:

Answer:
double displacement reaction
Explanation:
Answer:
All the elements in one group have the same number of valence electrons. ... Since elements in a group have the same number of valence electrons, they behave similarly in chemistry. An example would be the alkali metals (excepting hydrogen. Hydrogen is in this group only because it has one valence electron.
