Copper oxide(solid) + Sulphuric Acid (aqueous)-> Copper Sulphate (aqueous)+ Water(liquid)
In equation form:
CuO +H2SO4 -> CuSO4 + H2O
The colour change you will see is black to blue as Copper oxide is usually found as a black powder. Upon the reaction with sulphuric acid it will change to a cyan blue.
If you heat the made solution of copper sulphate, the water will evaporate and you will be left with white anhydrous copper sulphate crystals.
Answer:
The concentration of fructose-6-phosphate is 1.50x10⁻³M
Explanation:
Gibbs Free energy, ΔG°, is defined as:
ΔG° = -RTln K
<em>Where ΔG° = 1670J/mol</em>
<em>R is gas constant = 8.314J/molK</em>
<em>T is absolute temperature (25°C + 273.15 = 298.15K)</em>
Thus, equilibrium constant, k, is:
1670J/mol = -8.314J/molK* 298.15K ln K
-0.6737 = ln K
0.5098 = K
K of the reaction:
G6P ⇄ F6P
is:
K = 0.5098 = [F6P] / [G6P]
As [G6P] is 2.95x10⁻³M:
0.5098 = [F6P] / [2.95x10⁻³M]
[F6P] = 1.50x10⁻³M
<h3>The concentration of fructose-6-phosphate is 1.50x10⁻³M</h3>
Answer:
The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
![R=k[C_4H_6]^2](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5E2)
Explanation:
The rate of the reaction ;
![R=k[C_4H_6]^x](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5Ex)
As given in the question , that graph of time verses ![\frac{1}{[C_4H_6]}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BC_4H_6%5D%7D)
was linear but plots of ![[C_4H_6]](https://tex.z-dn.net/?f=%5BC_4H_6%5D)
or ![\ln[C_4H_6]](https://tex.z-dn.net/?f=%5Cln%5BC_4H_6%5D)
was curved.
Generally:
Graph of time verses ![[concentration]](https://tex.z-dn.net/?f=%5Bconcentration%5D)
for zero order reaction is linear with negative slope.
Graph of time verses ![\ln [concentration]](https://tex.z-dn.net/?f=%5Cln%20%5Bconcentration%5D)
for secon order reaction is linear with negative slope.
Graph of time verses ![\frac{1}{[concentration]}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Bconcentration%5D%7D)
for secon order reaction is linear with positive slope.
So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
