The only reactant in this decomposition reaction is potassium chlorate, KClO3. The manganese(IV) oxide is just a catalyst; it gets the reaction going but does not react. The gaseous product causes the glowing wood, paper or tobacco to combust, just like the methane in its combustion reaction in A2. What is the gaseous product of this decomposition reaction?

Standard airbags for automobiles used to implement the formation of sodium azide as a source of nitrogen gas. This has since been replaced due to the potential caustic nature of the products. The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen oxide in liquid ammonia: 3N2O(g) + 4Na(s) + NH3(l)→ NaN3(s) + 3NaOH(s) + 2N2(g) a. You have 65.0 g of sodium and a 35.0 L flask containing N2O gas with a pressure of 2.12 atm at 296 K. What is the maximum possible yield (in grams) of the NaN3?

Amounts of tin may be alloyed with copper to produce bronzes of varying composition and properties. 8.9394 g of a particular bronze, compounded of only Cu and Sn, can be quantitatively converted into a 11.2311-g mixture of the Oxides CuO and SnO2. (Use the atomic masses: Cu 63.546, Sn 118.71, O 15.9994.) What was the percentage (by mass) of tin in the alloy?

Platinum is an expensive and rare metal used in catalytic converters. Much research has been devoted to maximizing reactive properties of other less expensive metals by reducing their size to the nanoscale. Smaller particles are more reactive because they have a larger surface area to volume ratio. Which type of atom in a nanoparticle is more reactive? An atom on the surface of a particle An atom in the interior of a particle The location of an atom in the nanoparticle does not influence its reactivity.
