Answer:
There will be produced 3.5 moles of oxygen (O2)
Explanation:
Step 1: Data given
Number of moles Mercury (II) oxide (HgO) = 7 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 7 moles of Mercury (II) oxide (HgO) we'll have 7/2 = 3.5 moles of O2
There will be produced 3.5 moles of oxygen (O2)
Answer:
The force of gravity on earth is always equal to the weight of the object as found by the equation: Fgrav = m * g where g = 9.8 N/kg (on Earth) and m = mass (in kg) (Caution: do not confuse weight with mass.) The normal force is the support force exerted upon an object that is in contact with another stable object.
