You can use the equation ΔS(surr)=q(surr)/T or ΔS(surr)=-q(rxn)/T.
the two equations are equal since we know that the energy the system (reactoin) puts out just goes into the surroundings.
(In other words q(surr)=-q(rxn))
Using the equation, <span>ΔS(surr)=-(-283kJ/298K)=0.9497kJ/K or 949.7J/K
This answer makes sense since the reaction is exothermic which means it released energy into the system which usually causes the entropy to increase.
I hope that helps.</span>
Option a: alkene
Styren is C6H5CH=CH2, i.e. ethenylbenzene
Answer:
See Below for answer!
Explanation:
In order to find the number of orbitals given the principal quantum number, n, we can use 
. For example n=2 would have 8 orbitals.
A) 32
B) 98
C) 50
D) 18
Answer:
A<em>=</em><em>4</em>
<em>B</em><em>=</em><em> </em><em>4</em><em>+</em><em>2</em><em> </em><em>=</em><em>6</em>
<em>C</em><em>=</em><em>C</em><em>arbon</em>
<em>D</em><em>=</em><em>10</em>
<em>E</em><em>=</em><em>22</em>
<em>F</em><em>=</em><em>Argon</em><em> </em>
Answer: E
