Answer:
B. 2g
Explanation:
So first you have to find the mole to mole ratio then convert it to grams if that makes sense. So the mole to mole ratio is 2 ammonia to 3 hydrogen gas. So then after you do that conversion you can solve for grams then. Sorry I am not that great at explaining.
The correct answer is A. retina. Just took the pf test and got 100%
Explanation:
Mass (m)=0.3 kg
height(h)=2.6 m
acceleration due to gravity (g)=10m/s^2
Potential energy= MGH
=0.3×10×2.6
7.8 J

The reaction is that,
1 mole is SiCL4 will produce 1 mole of Si(s) Since there is 1 to 1 relationship then we just multiply the enthalpy of reaction by the number of moles
Enthalpy = -625.5 kJ/mole × 12.5 Moles
= -7,818.75 KJ
= -0.78 ×10⁴KJ
