Moles

[Sophia Dinh 1D]

When determining which side has more moles, do you account for the subscripts and the coefficients or just the coefficients?

[Jason Wu 1E]

To determine which side has more moles to calculate which direction Le Chatelier's principle deviates yo, you just need the compare the total of the coefficient of the products to that of the reactants AFTER you balance the chemical equation. The reaction will favor the side with lesser moles if you decrease the volume by compression and the reaction will favor the side with more moles if you increase volume by expansion.

Make sure you only count gaseous moles though, as liquids and solids are not noticeably affected by pressure changes to the equilibrium.

[Brandon Valafar]

You only count the gas atoms first. Then, moles go based off of coefficients, not the subscript.

[Sukanya Mohapatra 2G]

You only count the coefficients of gaseous molecules.

[Isabella Dal Porto 1H]

Many gases are just diatomic molecules or a combination of different elements. This doesn't affect the number of moles. Thus, you only need to consider the coefficient to get the number of moles.

[Vivianvelazquez_1J]

You only count gas molecules and their coefficients, not subscripts.

[SimranSangha4I]

It's primarily focused on gas molecules and their coefficients.

Just the coefficients for gaseous molecules!
