l:(COSpt) Explain in your own words what docs "decomposition" mcan? Give 2 examples of decomposition reactions. a sabstance that is brohen cocwn in to simpter substanceS qls) + y Lath, you will ced to caclate thepercentage of kC10, in a 2. (2pts) In the Stoichiometry mixture through its decomposition reaction a) Write down the balanced reaction equation for the decomposition of KC10,, and label each compound by its IUPAC name. b) How would you measure the weight of oxygen gas generated in this reaction? c) How would you know the reaction is complete, that all the KCIO, in the sample has been decomposed?Explanation / Answer
2
a) balanced equation : 2KClO3(s) ---> 2KCl(s) + 3O2(g)
name = KClO3 = potassium chlorate
KCl = potassium chloride
O2 = oxygen
b) by collecting releasinG O2 gas, determine the volume,pressure of gas and using ideal gas equation.it is possible to detremine mass of O2 gas.
c)as it is irreversible reaction.what ever the mass of KClO3 taken will be converts into products.that can be determined by comparying the no of mol of KClO3 taken,no of mol of KCl,O2 formed.
