When 100ml of Hg(NO3)2 (aq) fully reacted with Na2S (s), 1g of HgS was producted. In this situation, how much is the molarity of Hg(NO3)??

SO2 mixed with O2, 800K is in the 2.00L metal container and it was 1.9atm. The reaction occur and than pressure of container dropped to 1.65atm. How many SO3 was produced?

2AgNO3 + Zn -> 2Ag + Zn(NO3)2 Put Zn 19g and excessive amount of AgNO3 together in a beaker and start reaction. When Zn is still in a beaker, stop the reaction, and measure the mess of (Zn+Ag). Mass of (Zn+Ag) was 29g. Than what is the mass of Ag in (Zn+A...

Well I mean, the molarity of Hg(NO3)2. Not Hg(NO3)

Thanks a lot

My solution: 2SO2 + O2 -> 2SO3 When a reaction occurred once, 2 molecule of SO2 and 1 molecule of O2 are used, 2 molecule of SO2 is produced. This mean every one reaction loss one molecule on total and produce 2 molecule of SO3. N1=(1.9atm)(2.0L)/800KR =5...

You mean N1-N2 isnt number of reactions??
