D. 4
E. 6(3(2)=6)
F. 4(2(1)+2(1)[2+2=4)
G. 5(5(1)=5)
H. 4(2(1)+2(1)=2+2=4)
Explanation:
Coordination number= no of ligands
= No of ligands X denticity
Denticity is nothing but type of ligands like mono,do and tetradentate ligands.
<h2>Answer:</h2>
The correct answer is option C which is chemical waste.
<h3>Explanation:</h3>
- Wind is the renewable source of the energy. The air has energy in it which is used to run the generator to produce electrical energy from the mechanical energy of wind.
- Wind energy is perfect in sense of pollution. It does not create any chemical waste because there is no conversion or production of chemical energy involve in this energy production.
- While bats and birds death is caused by the fans used to run generators and a huge noise is also created by the wind energy production.
"<u>Nuclei</u>
" are called as building blocks of the universe.
Option: D
<u>Explanation</u>:
Smallest unit of this universe was considered to be an atom but “Rutherford 's Nuclear Model of Atom” in 1911 discovered nucleus which is small and heavy positively charged body present in center of atom. An atom also have extra nuclear part which is space around nucleus, where electrons (negative charged) are distributed. Nucleus is contained with protons (positive charged) and neutrons (neutral) which are definitely very smaller than nuclei but as a building unit or block of the universe nuclei is considered.
