Which formula demonstrates a double replacement reaction? 1. A + B --> AB
2. AB + CD --> AC + BD
3. AB --> A + B
4. A + BC --> AC + B

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

b.final

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

fe 55.85 g/mol and h2o 18.02 g/mol.
