Problem- when the reddish brown mercury ii oxide hgo is, Ask an Expert

Academics

Problem- When the reddish brown mercury (II) oxide, HgO, is heated, it decomposes to its elements, liquid mercury and oxygen gas:

HgO(s) ? Hg (l) + O2 (g)

Part 1- If 2.00g of mercury (II) oxide is decomposed, what is the mass of mercury liquid produced?

When lead(II) nitrate is added to an aqueous solution of sodium iodide, a precipitation reaction occurs that removes the iodide ion from solution.
Pb(NO3)2 (aq) + NaI (aq) ? PbI2 (s) + NaNO3 (aq)

Part2- If a solution contains 7.00g of NaI, what mass of lead(II) nitrate should be added to remove all of the iodide ion from solution?
