NAME REPORT FOR EXPERIMENT 9 DATE single Displacement Reactions NOTE: In this experiment, eopper ions will have 2+ charge Evidence of Reaction Equation (to be completed) Describe any evidence of reaction; if ne reaction was observed, write "None Write "No reaction", if no reaction was 2. g)no racfin QUESTIONS AND PROBLEMS 1. Complete the following table by writing the symbols of the two elements whose reactivi- ties are being compared in each test: Tube Number Greater activityCuTr Lesser activity haN 2 Arrange Pb, Mg, and Zn in order of their activities, listing the most active first.

Explanation / Answer

Posted the answers to first four problem, post multiple question to get the remaining answers

Q1) You have written the salts in few table, it should only be metal activity comparison. See the table below for correct answer

Q2)

Mg is replacing Zn, hence Mg activity is greater than Zn

Zn is replacing Pb, hence Zn activity is greater than Pb

Therefore correct order is Mg > Zn > Pb

Q3)

Correct order will be Zn > Cu > Ag

Reason: Cu is replacing AgNO3 from solution and Lead is replacing Copper but Zinc is replacing Pb, hence the correct order will be above as mentioned

Q4)

Correct order will be Mg > H > Ag

1 2 3 4 5 6 Greater Acitivity Cu Zn Mg H Zn Pb Lesser Activity Ag Pb Zn Cu H Cu
