Answer:
B only
Explanation:
Using the VSEPR principle, the electron bond pairs and the lone pairs on the middle atom help us predict the structure of the molecule. The shape of a molecule is determined by the position of the nucleus and its electrons. The electrons and the nucleus settle in positions that minimize repulsion and maximize attraction.
Answer:
63.55
Explanation:
relative atomic mass=(mass of isotope1×relative abundance)+(mass of isotope 2×relative abundance)/100
r.a.m=(62.93×69.09)+(64.93×30.91)/100
=(4347.8337)+(2006.9863)/100
=6354.82/100
=63.55
Nanowhiskers or cellulose nanofibers
are nano-structured cellulose produced by bacteria. They have relatively high
crystallinity and ability to form a dense network held together by
inter-fibrillar bonds that has the tendency to act as a barrier through their
film-forming properties to which they can repel stains on fabric.
