Why does heating of lead nitrate give brown fumes?
Heating lead nitrate causes it to decompose, forming nitrogen dioxide gas which appears as brown fumes. This occurs due to the oxidation of nitrogen from the nitrate ion in the lead nitrate. Lead oxide is also formed as a residue after the reaction.
What type of chemical reaction take place when lead nitrate is strongly heated?
When lead nitrate is strongly heated, it undergoes a decomposition reaction, forming lead oxide, nitrogen dioxide gas, and oxygen gas. This reaction is represented by the following equation: 2Pb(NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g)
What metal when It decomposes it heated it give zinc oxide?
Zinc oxide can be obtained by heating zinc nitrate.
Does mercuric oxide decompose on heating?
Mercuric oxide decomposes upon heating to give off mercury and oxygen.
Will calcium chloride give calcium oxide when heated?
No, calcium chloride will not give calcium oxide when heated. Calcium chloride is a salt compound, while calcium oxide is a different compound formed by heating calcium carbonate. Heating calcium chloride will decompose it into calcium chloride and release chlorine gas.
Why does heating of lead nitrate give brown fumes?
Heating lead nitrate causes it to decompose, forming nitrogen dioxide gas which appears as brown fumes. This occurs due to the oxidation of nitrogen from the nitrate ion in the lead nitrate. Lead oxide is also formed as a residue after the reaction.
What happens when lead nitrate crystals are heated?
When lead nitrate crystals are heated, they undergo a decomposition reaction, releasing nitrogen dioxide gas, oxygen gas, and leaving behind lead(II) oxide as a residue. This reaction can be represented by the equation: 2Pb(NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g).

Zinc oxide can be obtained by heating zinc nitrate.
Does mercuric oxide decompose on heating?
Mercuric oxide decomposes upon heating to give off mercury and oxygen.
Give 5 example subtances?
If we consider substance a synonym for compound: sodium chloride, uranyl nitrate, barium oxide, formic acid, lithium hydroxide.
Will calcium chloride give calcium oxide when heated?
No, calcium chloride will not give calcium oxide when heated. Calcium chloride is a salt compound, while calcium oxide is a different compound formed by heating calcium carbonate. Heating calcium chloride will decompose it into calcium chloride and release chlorine gas.
What ions do Nitric acid form in water?
HNO3 dissociates to give H+ and NO3- ions.
What does lead nitrate and potassium hydroxide?
Lead nitrate and potassium hydroxide react to form lead hydroxide and potassium nitrate. This reaction is a double displacement reaction where the positive ions switch places. Lead hydroxide is insoluble in water and forms a precipitate.
Will sodium carbonate give oxygen on heating?
sodium carbonate doesn't give any gas on heating. its sodium bi-carbonate which gives co2 on heating.
What happens when aluminium reacts with dilute nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
What are the products of cooper nitrate and strontium nitrate?
They only give a solution of these two compounds as a mixture.
