There is homework due 2/1 (t); see 'lesson plans and assignments. Having trouble with % yield? Go to u tube and watch some videos on how to do it.
go to this you tube video 5 types of chemical reactions
List the 5 types of reactions, with a general description of each, then, write a balanced chemical equations with states for the 5 reactions in the video. If your video doesn't work, make up 5 equations.
Next, watch this about the Hindenburg disaster
Find these answers on the internet if you don't know them.
What was the Hindenburg filled with?
What are today's blimps filled with? Why is this gas better?
Why wasn't the Hinbenburg filled with this safer gas?
What was the date and location of this disaster?
What country owned the Hindenburg?
What caused it to catch on fire?
Write a balanced chemical equation with states for the reaction that occurred as the Hindenburg burned. Classify the reaction as one of the 5 types, and tell whether it was and endo or exothermic reaction.
Then, using stochiometry, calculate the the mass of oxygen consumed and the mass of water formed when 45g of hydrogen gas is burned. Record your answers on this spreadsheet.
