what do you observe in the displacement reaction of zinc and lead nitrate?
also, what is the symbol equation for this reaction?
Zn (s) + Pb(NO3)2(aq) >> Pb(s) + Zn(NO3)2 (aq)
you observe lead precipitating on the zinc surface.
are there any notes about colour changes or note of any bubbles?
If this is a lab question, the answer should come from what you observed. The experimental setting is a zinc metal strip placed in a solution of lead nitrate. IF a reaction occurred, the zinc strip will lose some of its mass and its surface will become dull and covered with a loose deposit of a dark grey solid (metallic lead, Pb). DID any of this happened?
One more thing: If this is not a lab question and you are asked for a prediction, The reaction WILL occur if Zn is HIGHER than Pb on a "Metal Activity Series". If this is not so, the reaction will not occur, and the observation will be "No Change".
