Answer:
2/6
Explanation:
In a balanced chemical equation as:
aA + bB → cC + dD
Where coefficients of reaction relates the number of moles of substances that are involved in the reaction. In the reaction:
Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH₃(g)
Per mole of Mg₃N₂(s) and per 6 moles of H₂O you will produce 3 moles of Mg(OH)₂(s) and 2 moles of NH₃(g).
To convert moles of H₂O to moles of NH₃ you can use:
X moles of H₂O ₓ (2 moles NH₃ / 6 moles of H₂O)
That means conversion factor to convert the number of moles of water to number of moles of ammonia is <em>2/6</em>.
<em>-It is important to say that obtention of conversion factor requires, in the first, the balanced chemical equation-</em>

Answer:
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.
Explanation:
![2 AX_2(g)\rightarrow 2 AX(g) + X_2(g)](https://tex.z-dn.net/?f=2%20AX_2%28g%29%5Crightarrow%202%20AX%28g%29%20%2B%20X_2%28g%29)
Average rate of the reaction =![R_a](https://tex.z-dn.net/?f=R_a)
![R_a=-\frac{\Delta [x]}{\Delta T}=-\frac{x_2-x_1}{t_2-t_1}](https://tex.z-dn.net/?f=R_a%3D-%5Cfrac%7B%5CDelta%20%5Bx%5D%7D%7B%5CDelta%20T%7D%3D-%5Cfrac%7Bx_2-x_1%7D%7Bt_2-t_1%7D)
=Average rate of the reaction during the given time interval.
= Change in concentration of reactant with respect to time.
= Change in time.
=Concentration of reactant at time![t_1](https://tex.z-dn.net/?f=t_1)
=Concentration of reactant at time![t_2](https://tex.z-dn.net/?f=t_2)
So, at
the concentration of
:
![x_1=0.0249 mol/L](https://tex.z-dn.net/?f=x_1%3D0.0249%20mol%2FL)
And at
the concentration of
:
![x_2=0.0088 mol/L](https://tex.z-dn.net/?f=x_2%3D0.0088%20mol%2FL)
The average rate of the reaction at given interval will be given as:
![R_a=-\frac{x_2-x_1}{t_2-t_1}=-\frac{0.0088 mol/L-0.0249mol/L}{20.0s-8.0 s}=0.001341 mol/L s](https://tex.z-dn.net/?f=R_a%3D-%5Cfrac%7Bx_2-x_1%7D%7Bt_2-t_1%7D%3D-%5Cfrac%7B0.0088%20mol%2FL-0.0249mol%2FL%7D%7B20.0s-8.0%20s%7D%3D0.001341%20mol%2FL%20s)
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.

Explanation:
got it right on edge :))))
D. There is one atom of sulfur and three atoms of oxygen.
The "tri" in trioxide indicates three so there are three atoms of oxygen. As nothing is said about the sulfur, there is just one atom.
Hope this helps!!
