Consider the combustion of propane: C3H3 + 502 - 3C02 + 4H20 Which of the following unit factors below is correct? (Select all that may apply) There are 10 oxygen atoms reacting for every six oxygen atomş produced in CO2.
There are 10 oxygen atoms reacting for every four water molecules produced.
There are 5 oxygen molecules reacting for every six oxygen atoms produced in CO2.
There are 5 oxygen atoms reacting for every 3 CO2 molecules produced.​

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
