Explanation:
Gold(I) Nitride Au3N Molecular Weigh.
Answer:
0.229 M/s is molecular nitrogen reacting
Explanation:
Rate of the reaction :
![R=-\frac{1}{1}\frac{d[N_2]}{dt}=-\frac{1}{3}\frac{d[H_2]}{dt}=\frac{1}{2}\frac{d[NH_3]}{dt}](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BN_2%5D%7D%7Bdt%7D%3D-%5Cfrac%7B1%7D%7B3%7D%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7Bd%5BNH_3%5D%7D%7Bdt%7D)

![-\frac{1}{1}\frac{d[N_2]}{dt}=-\frac{1}{3}\frac{d[H_2]}{dt}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BN_2%5D%7D%7Bdt%7D%3D-%5Cfrac%7B1%7D%7B3%7D%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D)
![\frac{d[N_2]}{dt}=\frac{1}{3}\times 0.0687 M/s](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BN_2%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%200.0687%20M%2Fs)
0.229 M/s is molecular nitrogen reacting
What mass of the following chemicals is needed to make the solutions indicated?
Answer:
271.6g
Explanation:
The mass of the chemicals need to make the needed solution can be derived by obtaining the number of moles first.
Given parameters:
Volume of solution = 1L
Molarity of HgCl₂ = 1M
number of moles of HgCl₂ = molarity of solution x volume
= 1 x 1
= 1 mole
From;
Mass of a substance = number of moles x molar mass;
we can find mass;
Molar mass of HgCl₂ = 200.6 + 2(35.5) = 271.6g/mol
Mass of the substance = 1 x 271.6 = 271.6g
