Practice: Which of the following represents the formation equation for barium nitrate, Ba(NO3)2?
Formation Equations involve the standard states of elements combining to form 1 mole of product.
Concept #1: The Natural State (Standard State)
Elements can exist as solids, liquids or gases at 25ºC and 1 atm standard pressure.
Example #1: Which of the following elements is found in its standard state?
Example #2: Write the formation equation for methanethiol, CH3SH.
Practice: Which of the following represents the formation equation for barium nitrate, Ba(NO3)2?
Practice: Identify a substance that is not in its standard state.
Practice: Ibuprofen is used as an anti-inflammatory agent used to deal with pain and bring down fevers. If it has a molecular formula of C13H18O2, determine the balanced chemical equation that would give you directly the enthalpy of formation for ibuprofen.
