Hello!

The answer is: Write the dimensional analysis.

Why?

Let's remember the basic steps to complete a stoichiometric calculation:

First: The first thing we need to do is balance the equation in order to have a properly formed equation.

Second: Convert the given units of the element or substance into moles. Working with moles will make the calculations easier. For example, if we are looking for an empirical formula of a compound.

Third: Writing the mole ratio will give us the required information to make a stoichiometric calculation, since the mole ratio tells us the way the reaction will happen, the relation between the reactants and products, writing the mole ratio is required.

Dimensional analysis is not required to complete a toichiometric calculation since it's only needed if we need to make a relation between units of a determinate substance, for example mL to L, and so. Dimensional analysis is related to physical properties

Have a nice day!

Answer from: thepantsgirl

Write the dimensional analysis.

Explanation:

Dimensional analysis is required when we have to deal with different kinds of units of a same physical quantity. For example if we are provided with two or more units of length, then we need to convert one unit to other.

In stoichiometric calculations:

a) we need the mole ratio of reactants and products

b) the mole ratio is obtained by writting balanced chemical reaction.

c) then we write the number of atoms in a mole of the product.

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
