Group 1
Group 2
Group 16
Group 18
Answers
Answer:
group 1
Explanation:
chlorine donate electron
Chlorine will more likely to form bonds with the elements of group 1 as it has 7 valence electrons.
Chlorine element:Chlorine is an element that is present in group 17. This family is also known as the Halogen family. The elements of this group will have seven electrons in their outermost shell. It has only one electron less to attain a stable noble electron configuration.
Thus, it will form bond more readily with Group 1 that has only one electron in its outermost shell.
Thus, correct option is a.

which substance is reduced ?
Cl^2 +2KBr= 2KCl + Br2
Answers
Answer:
Initially Br is in -1 oxidation state and Cl in 0 oxidation state. Finally Cl is in -1 o.s. and Br in 0.
This means that Br has oxidised from -1 to 0 and Cl is reduced from 0 to -1.
KBr is reducting agent as it helps Cl to reduce.
Cl2 is oxidising agent as it helps Br to oxidise.

Is there a solution for the impacts overfishing?
Answers
Answer:
The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.
