Which of the following is an incorrect step to do a complete stoichiometric calculation? write the mole ratio. write the dimensional analysis. write the balanced chemical equation. write the number of atoms in a mole of the product

The answer is: Write the dimensional analysis.

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!

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.

answer: c.

explanation:

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
