B). how many mole of mercury (hg) would be produced from reacting 6 mole of hgo (mercury (ii)
oxide)?

There will be produced 6.00 moles of mercury (Hg)

Explanation:

Step 1: Data given

Number of moles Mercury (II) oxide (HgO) = 6.00 moles

Step 2: The balanced equation

2HgO → O2 + 2Hg

Step 3: Calculate number of moles of O2

For 2 moles of Mercury (II) oxide (HgO) we produce 1 mol of O2 and 2 moles of Hg

For 6.00 moles of Mercury (II) oxide (HgO) we'll have 6.00 moles of mercury (Hg)

There will be produced 6.00 moles of mercury (Hg)
