What role does water play in a nuclear power plant? Select all that apply. The metal rods holding the nuclear fuel pellets are stored in a pool of water, which absorbs the neutrons produced and controls the rate of the nuclear reactions.
Liquid water absorbs some of the heat of the reaction, which helps to control the reactions.
Water chemically reacts with uranium, which causes uranium to emit neutrons and produce a chain reaction.
Liquid water is boiled to steam, which is pressurized and turns the turbine to produce electricity.

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
