Lexi is balancing equations. She is finding one equation to be very difficult to balance. Which explains how to balance the equation ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4? One reactant and one product needs the coefficient 2.
The products both need a 3 coefficient.
The reactants both need a 2 coefficient.
Atoms in the equation are already in balance.

The statement that best explains how to balance the equation: ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4 is: atoms in the equation are already in balance.

HOW TO BALANCE A CHEMICAL EQUATION:

A chemical equation is said to be balanced if the number of atoms of each element in the reactant side is equal to that on the product side.

In the equation given in this question as follows:

ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4

There are:1 atom of Zn on both sides of the equation1 atom of sulfur on both sides of the equation7 atoms of oxygen on both sides of the equation2 atoms of lithium on both sides of the equation. Since the number of atoms of each element on both sides of the equation are the same, hence, the equation is said to be balanced. Therefore, the statement that best explains how to balance the equation: ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4 is: atoms in the equation are already in balance.

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
