Answer:
The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
Explanation:
The rate of the reaction ;
As given in the question , that graph of time verses was linear but plots of or was curved.
Generally:
Graph of time verses for zero order reaction is linear with negative slope.
Graph of time verses for secon order reaction is linear with negative slope.
Graph of time verses 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 :
F,g,a can be used to get ''h''
Answer:
c) HCl and NaCl
Explanation:
Since all the solutions are on a 1:1 mole ratio the comparison is straight forward.
The lowest pH will be for solution c) which has a strong acid, HCl, which ionizes 100 % and the neutral salt NaCl (which is neutral since it is derived from the reaction of the strong acid HCl and the strong base NaOH).
Solutions a) and b) are buffers of the weak base NH₃ and its conjugate acid NH₄⁺ and weak acid H₃PO₄ and its conjugate weak base NaH₂PO₄ respectively.
Solution c) is a basic solution being a mixture of the weak base NH₃ and the strong base NaOH
Solution e) is a mixture of a weak base NH₂ and weak acid HC₂H₃O₂
Answer:
15 neutrons
Explanation:
the atomic mass shows the amount of neutrons and protons added together
the atomic number shows us how many protons they are (you can also find out how many electrons a element has by looking at its atomic number as it will have the same amount of protons)
so to find the amount of neutrons the sample has you have you subtract the atomic number which is the amount of protons from the mass number which tells us the amount of neutrons and protons added together but we only need the neutrons that's why we subtract it
33-18=15
