Group 17 (or 7A, or VIIA): Halogens.
<h3>Further explanation</h3>This group contains the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements occur naturally in a diatomic structure
Halogens are the most highly reactive nonmetals. Therefore, they become negative one charged ions by gaining a single electron to complete their valence shell in the chemical reaction.
Thus, if a new element were discovered and it was found to form 1− ions, we would place it in the periodic table as a member of group 17, also known as group 7A or VIIA or halogens.

The final temperature : 78.925°C
<h3>Further explanation </h3>Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Energy releases = 130 kcal = 130 x 4.18 kJ=543.4 kJ
The final temperature :
Final temperature :
ΔT=final-initial
51.925°c=final-27°c
final = 51.925+27=78.925°C
Answer:
Average rate of reaction is 0.000565 M/min
Explanation:
Applying law of mass action for the given reaction:
Average rate =
Where, represents average rate of disappearance of
,
represents average rate of appearance of
and
represents average rate of appearance of
Here, =
So average rate of reaction = [/tex] =
