Answer:
Average rate of reaction is 0.000565 M/min
Explanation:
Applying law of mass action for the given reaction:
Average rate = ![-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}=\frac{1}{4}\frac{\Delta [NO_{2}]}{\Delta t}=\frac{\Delta [O_{2}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7B%5CDelta%20%5BNO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B%5CDelta%20%5BO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
Where, ![-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of disappearance of 
, ![\frac{1}{4}\frac{[NO_{2}]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7B%5BNO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of appearance of 
and ![\frac{[O_{2}]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of appearance of 
Here,![-\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)
= 
So average rate of reaction = ![[tex]-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=%5Btex%5D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)

Answer:
6) 225.8 g
7) 1.01 g
8) 21.624 g
Explanation:
6) Molar Mass of Lithium Bromine: 86.845
86.845 * 2.6 = 225.8 g
7) Molar Mass of Neon: 20.180
20.180 * 0.05 = 1.01 g
8) Molar Mass of Water Vapor: 18.02
18.02 * 1.2 = 21.624 g
The convection current is one of hot air rising, in this example, and then cooling and returning down. The rising air pushes the eagle up higher into the air. It just has to spread its wings and let the air push it into the air
Answer:
(A). C6H5Br + Mg(in ether) -----------> C6H5MgBr.
(B). C6H5MgBr + O = C = O -----------> C6H5-COO^- Mg^+ Br.
(C). C6H5-COO^- Mg^+ Br + HCl --------> C6H5-COOH + Mg^+Br(OH).
PRODUCTS=> C6H5-COOH and Mg^+Br(OH).
Explanation:
A Grignard reagent is a reagent that/which is an organometallic compound that is R -Mg- X. The R = alkyl, vinyl or allyl and the X = halogens.
It must be noted that an important reaction of Grignard reagent is its reaction with compounds containing the Carbonyl that is -CO functional group and this kind of Reaction is known as a Grignard Reaction.
So, in this question we are told that;
=> "1-bromo-benzene andits subsequent reaction with solid carbon dioxide (CO2) followed by acidic workup (using HCl asthe acid). "
Thus;
(A). C6H5Br + Mg(in ether) -----------> C6H5MgBr.
(B). C6H5MgBr + O = C = O -----------> C6H5-COO^- Mg^+ Br.
(C). C6H5-COO^- Mg^+ Br + HCl --------> C6H5-COOH + Mg^+Br(OH).
