Is thermal decomposition the same as melting point? If it's not, I'm not sure on where to look up thermal decomposition values for compounds. Please help!
The question is asking to find the temperatures at which the solids listed below thermally decompose.
- sodium chloride
- magnesium carbonate
- calcium oxalate
- calcium carbonate
Homework Answers
Thermal decomposition is the breaking down of a chemical compound which is done by heat so that it is a chemical change new products are formed while melting is a physical change no new product is formed
1) nearly 800 0C
2)350 0c
3)479 0c
4) 840 0c

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
