Write the balance chemical equation Lead oxide + Carbon = Lead + Carbon dioxide. From the eqution, determine which reactant is oxidised and which is reduced. |
| Answer» EXPLANATION:Hey mate here's your ANSWER Word Equation Lead (II) oxide + Carbon → Lead + Carbon dioxide Formula Equation 2PbO (s) + C (s) → 2Pb (s) + CO2 (g) Yellow lead (II) oxide (litharge) was mixed with powdered charcoal in a CRUCIBLE. This was heated on a pipe-clay triangle on a tripod with a roaring bunsen flame and occasionally stirred. After 15 minutes small globules of molten lead were PRODUCED. Note : Carbon at first is partially oxidised to form carbon MONOXIDE (PbO + C → Pb + CO) which then is involved in further reduction (PbO + CO → Pb + CO2). A mixture of gases would be expected with carbon dioxide being the dominant form. | |
