(to see if it can evaporate)
<span>Answer:
Pb(NO3)2+2HCl=PbCl2+2HNO3
Step 2
Find # of moles of Pb
13.87g Pb(NO3)2 x 1 mol/331.22=.041875 mol Pb(NO3)2
Step 3
Use balanced equation to find weight of Pb(NO3)2
.041875mol Pb x 1 mol Cl2/1mol Pb x 70.90g/1 mol Cl2=2.9689g Cl2
.041875 mol Pb x 207.2/1mol Pb=8.6765g Pb
=11.65g</span>
The answer to this is <span>4 Al + 3 O2 = 2 Al2O3 i hope that this helps</span>
