Hello! If you can't do all of them it's totally okay, but would be much appreciated.
For each of these I need the Lewis structure, VSEPR, how many polar bonds and if it is a resonance structure.

1. HSCN
2. CSO
3. BFO
4. PI3F2
5. NF3 (nitrogen triflouride)

It is sure ( overimitation)

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

Ithink about 50 % of an original isotope's number of atoms remain

Atp, shorthand for adenosine triphosphate, is the standard molecule for cellular enger in the human body. all motion and metabolic  processes  within the body begins with energy that is released from  atp, as its phosphate bonds are broken in cells through a  process  called hydrolysis.
