Answer:
15.63
Explanation:
i just took it on edgeunity
15.63 mol . You need 15.63 mol HgO to produce 250.0 g O_2.
<em>Step 1 </em>. Convert <em>grams of O_2 to moles of O_2 </em>
Moles of O_2 = 250.0 g O_2 × (1 mol O_2/32.00 g O_2) = 7.8125 mol O_2
<em>Step 2 </em>. Use the molar ratio of HgO:O_2 to convert <em>moles of O_2 to moles of HgO
</em>
Moles of HgO = 0.8885 mol O_2 × (2 mol HgO/1 mol O_2) = <em>15.63 mol HgO </em>

Answer:
0.029mol
Explanation:
from
n=m÷mr
where
n is number of moles
m is mass
mr is molar mass
By decreasing n we can increase presure because decrease in n will shift equilibrium to either forward or reverse direction
Answer:

To determine the heat dissipated when a substance freezes, we multiply the heat of fusion of the substance to the mass of the substance that freezes. We calculate as follows: Heat = -3.16 (64/32.06) = - 6.32 kJ Hope this answers the question.
