Halogens are rarely found in native state because halogens are highly reactive.
<h3>
What is Halogens ?</h3>
The group 17 elements are known as Halogen group. These elements include Fluorine, Chlorine, Bromine, Iodine and Astatine. Halogens react with metals to form salts. Halogens are non metals. Halogens are highly reactive and halogens are never found in pure form. Halogens not occur in free state.
<h3>How many valence electron are present in Halogens ?</h3>
Halogens have seven valence electrons in the outermost shell. The electronic configuration of Halogen is ns² np⁵.
Thus from the above conclusion we can say that Halogens are rarely found in native state because halogens are highly reactive.

Answer:
is there a picture.....????
Answer is given below
Explanation:
given data
weight = 6N
temp = 105° C
weight reduced = 5N
solution
weight of container is 1N
SO W = (6-1) = 5
And Wd = 5 - 1 = 4
so
moisture content is
moisture content = .......1
moisture content =
moisture content = 25%
and
as we know density of soil soild = 2700 kg/m³
density of water = 1000 kg/m³
and sp gravity of soil = = 2.7
so
now we get here bulk unit weight
bulk unit wt = ..........2
bulk unit wt =
bulk unit wt = 19.766 KN/m³
and
so dry unit wt will be
dry unit wt = ..............3
dry unit wt =
dry unit wt = 15.813 kN/m³
The answer is 2.18 moles MgSi03.
