Which statement is true about the force of gravity? a. the earth has a greater gravitational effect than the sun. b. the moon has a greater gravitational effect that the sun. c. the moon has a greater gravitational effect than the earth. d. the sun has a greater gravitational effect than the earth. i  just took the quiz and its d

Answer is: D. The sun has a greater gravitational effect than the earth. 
Gravity as a force which causes any two bodies to be attracted to each other. The gravitational effect increases as the size of an object increases. Earth s surrounded by its own gravitational field.

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 

Olá. porque a reação na temperatura é muito rapida a do copo : )
