Question

on heating lead nitrate which of the following pair of gases will be evolved​

Answer 1

When lead nitrate is heated it decomposes to form a lead oxide, nitrogen dioxide and oxygen. Thus, lead nitrate on decomposition gives lead oxide, nitrogen dioxide and oxygen.

Thermal decomposition reaction:

• Thermal breakdown is a related series of events place heat is a reactant. Since heat is a catalyst, these backlashes are endothermic signification that the response requires warm strength to break the synthetic bonds in the fragment.
• Decomposition backlashes happen versatile us, but we frequently don’t notice ruling class. Some low examples of breakdown backlashes are determined beneath.
• The decomposition of colorless odorless gas in smooth drinks, that maybe presented by the synthetic equating H2CO3 → H2O + CO2.
• The electrolysis of water to yield hydrogen and oxygen.One main use of decomposition backlashes is in the ancestry of metals from their minerals.
• For example, metallic mineral maybe obtained from calamine by subject it to a breakdown backlash. In a identical manner, sodium maybe acquired from seasoning (NaCl).

Answer 2

Answer:

When lead nitrate is heated it decomposes to form a lead oxide, nitrogen dioxide and oxygen. Thus, lead nitrate on decomposition gives lead oxide, nitrogen dioxide and oxygen.

Explanation:-

Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colorless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.

Property-Known since the Middle Ages by the name plumbum dulce, the production of lead(II) nitrate from either metallic lead or lead oxide in nitric acid was small-scale, for direct use in making other lead compounds. In the nineteenth century lead(II) nitrate began to be produced commercially in Europe and the United States. Historically, the main use was as a raw material in the production of pigments for lead paints, but such paints have been superseded by less toxic paints based on titanium dioxide. Other industrial uses included heat stabilization in nylon and polyesters, and in coatings of photothermographic paper. Since around the year 2000, lead(II) nitrate has begun to be used in gold cyanidation.

Piousness-Lead(II) nitrate is toxic and must be handled with care to prevent inhalation, ingestion and skin contact. Due to its hazardous nature, the limited applications of lead(II) nitrate are under constant scrutiny.
