Question

112dm³ oxygen gas collected at stp, when lead(ii)nitrate decomposed. calculate the volume of nitrogen dioxide gas produced ?

Answer 1

Explanation:

When lead(II) nitrate is heated, it decomposes into lead (II) oxide, nitrogen dioxide and oxygen. The balanced chemical equation for this reaction is

2Pb(NO3)2(s)→2PbO(s)+4NO2+O2(g)

 Lead (II) nitrate is also called lead nitrate or plumbous nitrate. The heating of lead nitrate does produce toxic fumes of lead and nitrogen dioxide. The temperature at which this compound decomposes is 878 degrees Fahrenheit.
