![r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B%20k%20%5BNO_2%5D%5E2%20%5BF_2%5D%7D%7B%5BNO_2F%5D%7D)
Explanation:
From the question we are told that
The formation mechanism is


The overall balanced equation is

We combined the first reactant and the last product and the balanced the number of mole
The observable rate law is
![r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B%20k%20%5BNO_2%5D%5E2%20%5BF_2%5D%7D%7B%5BNO_2F%5D%7D)
This rate law is derived from the balanced chemical equation
Answer:
Option D is good to go!
Explanation: as per the reactivity series more reactive substances will react with the counterpart substance.The most reactive substance here is calcium while the least reactive is aluminium, the magnesium comes in between.As per their reactivity, these substances will react with oxygen.
Explanation:
C. 0.5
This is the answer.
(assuming that the D option is 1, if it is 0.1 then the answer is 0.1)
Answer:
Mass of liquid: 20.421g
Density= 1.0109405940594 g/mL
Explanation:
Mass of liquid
To find mass of liquid you take the mass of beaker + liquid (171.223g) and subtract it from the Mass of beaker (beaker without the water). The difference is the answer.
171.223g - 150.802g = 20.421g
Density
To find density you use the formula Mass/Volume. Take the Volume given, and the mass of the liquid you just found.
20.421mL/20.421g = 1.0109405940594 g/mL
