O only as products earns no credit. Any valid redox product earns one product point. Any valid redox product earns one product point. O only earns no credit. The vapor pressure of pure H 2 O is greater than the vapor pressure of H 2 O in solution.
O is greater than that from the sugar solution, while the condensation rates are the same.
The external pressure on the water will become equal to the vapor pressure of the water, causing it to boil. OR The drop in external pressure causes the boiling point to drop to the temperature of the water. No reaction occurs with silver. Zinc is a better reducing agent or a more active metal than copper and will be oxidized. Silver is a less reactive metal than copper is.
