CH17 – IDF

Patricia Bath

Date

• Friday, February 16th

Recap – S’mores

• write the reaction for the production of s’mores
• write down the available material on hand [48 Cr, 32 Ch, 40 Mm]
• how do I predict s’mores production?
• how do I predict leftovers?

New Idea – IDF

• Initial, Change, Final
• The table is a COUNTING table (only moles)
• the middle row reflects the mole ratio
• to repeat: this table only works with moles
• maybe have to do work BEFORE the table

Practice

• combustion of hydrogen (moles)
• combustion of hydrogen (mass)

Homework

• NO WAY! BREAK!
