Which statements correctly describe the process of nuclear fusion?

it happens only to large atoms.
it occurs naturally in the sun.
it releases a large amount of energy.
it bonds atoms together to create molecules.
it involves the joining of two atomic nuclei.

The following options are correct about nuclear fusion

It occurs naturally in the Sun.It releases a large amount of energy.It involves the joining of two atomic nucleiExplanation:

In Physics ,a nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei. It releases a large amount of energy and the nucleus made by fusion is heavier than either of the starting nuclei. This reaction naturally occurs on the sun as Hydrogen atoms are fused together to make helium.

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
