Pure oxygen gas was first prepared by heating mercury (ii) oxide, hgo: 2hgo(s)→2hg(l)+o2(g) what volume (in l) of oxygen at stp is released by heating 10.36 g of hgo?

Moles HgO = 10.36 g/ 216.59 g/mol= 0.048 the ratio between HgO and O2 is 2 : 1 moles O2 formed = 0.048/ 2= 0.024 at STP one mole of any gas occupies 22.4 L Volume O2 = 0.024 x 22.4 L/mol = 0.54 L

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .

Theoretical temperature at which molecules stop moving and no more heat can be removed from the object. kelvin: absolute zero degrees. none of the above.
