Re: Theoretical Yield [ENDORSED]

The theoretical yield is the amount of moles of product in grams. To calculate the theoretical yield, the steps for solving the limiting reactant of an equation must be completed, such that being the moles of the reactant are compared to the required moles. After making this comparison, the limiting...

Re: Definition of moles [ENDORSED]

An exact definition of moles is that a mole is a unit of measurement for the amount or sample of a chemical substance that contains as many constitutive particles as there are atoms in 12 grams of carbon-12, which can also be expressed by the Avogadro constant (6.022 x 10^23).

Re: How to Balance [ENDORSED]

The regular process to balance a chemical equation consists of counting the amount of atoms in both the reactants and products because the mass on the left must equal the mass on the right. With this being stated, coefficients are used to balance between the elements on the left and right of the equ...

Re: Molecular to Empirical [ENDORSED]

When presented with just a molecular formula, the empirical formula can be found by dividing by the greatest whole number that each element is divisible by. However, if the molecular formula is not able to be divided by any number, the empirical formula is known to be the same as the molecular formu...

Re: Reactant vs. Reagent [ENDORSED]

Reactant and reagent are known to often be used interchangeably; however, a reactant is more specifically a substance consumed in a chemical reaction, whereas, reagents are substances or compounds that are added to see if a chemical reaction will occur.

Re: Why are sig figs important?

Significant figures are important because they allow us to keep track of the quality of measurements. Essentially, sig figs demonstrate how much to round, while also making sure that the answer is not more precise than our starting value. Sig figs help build accuracy and precision among answers beca...
