easy! you would need to add universal indicator and if the pH turned alkaline you would know it was a metal. if it turned acidic however, it would show the characteristics of a non metal. grace x aged 14
Lead being less electropositive will be given out
Lead.
Lead Oxide + Carbon = Lead + carbon dioxide
Lead, since it is the only metal present in the reaction
Lead carbonate
lead
lead
Lead oxide is not a metal. Why?Lead is metal by itself, lead oxide is metal oxide, meaning it is a chemical compound that contains at least one atom of oxygen (thus oxide) and one other element (being a metal oxide, that one other element has to be metal, in this case lead).
No.Lead (ii) carbonate --> lead (ii) oxide + carbon
It is endothermic
2PbO + C ------> 2Pb + CO2 so metallic lead and carbon dioxide.
lead oxide + carbon-> lead + carbon dioxide
When lead oxide is heated with carbon, carbon dioxide and lead are formed as the products 2PbO+C -->CO2+2Pb

No.Lead (ii) carbonate --> lead (ii) oxide + carbon
The chemical reaction is:2 PbO + C = 2 Pb + CO2
lead oxide
1,4 moles of lead(II) oxide are formed.
It is endothermic
2PbO + C ------> 2Pb + CO2 so metallic lead and carbon dioxide.
