Answer:
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
The reactivity series allows us to predict how metals will react. A more reactive metal will displace a less reactive metal from a compound. Rusting is an oxidation reaction. Chemistry (Single Science)
SOL:-WE KNOW THAT SEX RATIO =NO OF MALES/NO FEMALES X100
=151,781,326/156,964,212X100
=0.9669804X100
=96.69(APPROXIMATELY)
OR
WE KNOW THAT SEX RATIO =NO OF MALES/NO OF FEMALES X100
=151,781,326/156,964,212X100
=151/156(+4) =150/160=15/16
=15/16X4=15/4=3.75
151+3.75/160=154.75/160X100
154.75/16X10
=154.75/8X5
19.34X596.69
=96.70 ANS
