Lead metal is produced by heating solid lead(II) sulfide with solid lead(II) sulfate, resulting in liquid lead and sulfur dioxide gas. Write a balanced equation for the reaction using complete formulas for the compounds with phase labels.
Pb2S(s) + Pb2SO4= 4Pb(l)+2SO2

Your equation should be
PbS + PbSO4 --> 2Pb(l) + 2SO2(g)

Lead(II) sulfate means that the formal charge on the Pb is +2. The sulfate ion has a formal charge of -2, so the formula for lead(II) sulfate is PbSO4 (not Pb2SO4).
(There is also a lead(IV) sulfate. In this salt, the lead has a formal charge of +4, so the formula would be Pb(SO4)2. As far as I know, there is no Pb(I) sulfate, which would be the name for the formula you were using.)
Similarly, the charge on the sulfide ion in lead(II) sulfide is -1, so the formula for this compound sould be PbS2 (not Pb2S).
Use these formulas in your reaction and rebalance it.

Wrongs would be diverse between cultures and can substitute by the years. some cultures have faith that categorical nutrition would desire to be arranged in a undeniable way and it fairly is incorrect to do in any different case. that erroneous my have greater earlier refrigeration grew to become into attainable and so would not be suitable. on the different hand, there will be some who save on with the custom merely simply by fact it labored for past generations. for people who believed interior the want for racial purity some human beings it grew to become into incorrect to have built-in faculties, shared eating places and lavatories. for people who believed in male superiority, it was once incorrect for women folk to anticipate equivalent pay. For populations that have been dying simply by fact of sickness or dying in conflict and organic disaster, you could actually think of that homosexuality grew to become into discouraged simply by fact it diverted sexual potential from duplicate. i've got faith that in case you examine the ten Commandments you will locate that each and every grew to become into defined to deter movements that tended to have undesirable effects for those societies at that component and doubtless nonetheless does. in lots of circumstances, merely as you have defined and to the greater worldwide of the 21st century, those undesirable effects look quite logical. In Biblical cases, purely some understood the coolest judgment or had the understanding. Moses grew to become into very smart certainly and knew that the long suffering Tribes could never have believed he would desire to individually have such understanding yet whilst he defined those simply by fact the words of God, nicely . . . . . .

ROFLMAO.
You're not getting a scholarship, now are you?
Okay, here's what your'e doing wrong: expecting someone to actually answer that.
Next stop, the library.
