Compare the mechanisms for the following substitution and addition reactions of benzene:
o the Friedel-Crafts reaction
o the sulfonation of benzene
o the chlorination of benzene
o the hydrogenation benzene
You will need to illustrate and explain the reaction mechanism for each one, as well as the similarities and differences that exist between them.
Could you list some similarities and differences for each mechanisms please?
Compare and contrast the 7 crystal system.
One mole is the amount of any given chemical substance that helps us to measure it's mass conveniently on a scale of C12 Isotope.
How many particles (atoms of carbon) are present in 12 g of C12 isotope of a naturally occuring sample of carbon.
Why we always choose ammonia to prepare the buffer solution with pH=10 but not the methylamine?
calculate the average atomic mass of sulfur if 95.00 of all sulfur atoms have a mass of 31.972 u, 0.76% has a mass of 32.971 u and 4.22% has a mass of 33.967u
Explain different types of thermodynamic systems with suitable examples.
Define chemical thermodynamics and outline its significance.
At 1000K, Kp = 1.85 for the reaction
What is the value of Kp for the reaction
Compare 1.0 mol/L sodium hydroxide with 1.0 mol/L ammonia (written as ammonium hydroxide) by recreating similar diagrams of dissociation and concentration as those provided to you for the acid comparison. Assume ammonia dissociates only 1%. What would you expect to see if you tested the conductivity and pH of each? Why is there a difference in reactivity if there is 1 mole of acid in a given litre?
The rate of a reaction at 25 °C is 2×+0^-3.Then the rate of reaction at 35°Cis approximately
