1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane
4. 3,4-dimethyl hexene
5. 3,4-dimethyl cyclobutene
6. 3,5 diisopropyl cyclohexene
7. 3,3,4 trimethyl pentyne
8. 2,6 dibromo phenol
keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1
Answer:
The value of the equilibrium constant KC is 1.244
Explanation:
A mixture initially contains A, B, and C in the following concentrations: [A] = 0.550 M, [B] = 1.40 M, and [C] = 0.600 M. The following reaction occurs and equilibrium is established: A+2B<->C
At equilibrium, [A] = 0.430 M and [C] = 0.720 M. Calculate the value of the equilibrium constant, Kc
Step 1: The balanced equation
A+2B<->C
Step 2: The initial concentrations
[A] = 0.550 M
[B]= 1.40 M
[C] = 0.600 M
Step 3: The concentraions at equilibrium
[A] = 0.550 -X = 0.430 M
[B]= 1.40 -2X M
[C] = 0.600 + X = 0.720 M
X = 0.120 M
[A] = 0.550 - 0.120 = 0.430 M
[B]= 1.40 -2*0.120 = 1.16 M
[C] = 0.600 + 0.120 = 0.720 M
Step 4: Calculate Kc
Kc = [C] / [A][B]²
Kc = 0.720 / (0.430*1.16²)
Kc = 1.244
The value of the equilibrium constant KC is 1.244
<h2>Answer : Law of conservation of mass</h2><h3>Explanation :</h3>
The law of conservation of mass states that in any reaction mass is neither created nor lost it has to remain constant in a system.
In this case, when the reaction setup was done in normal way the mass was lost in surrounding was not considered nor being calculated; whereas when the reaction was studied in a closed system where the gas was collected after the reaction the mass changes was noted down which helped to prove the point of law of conservation of mass and energy.
One can consider an example of soda can where the carbonated drink contains pressurized carbon dioxide gas. when opened the gas bubbles gets lost into the surroundings and we don't measure the mass changes. Instead if the soda can was opened in such a way where the gas evolved was measured then the mass changed would remain the same.
Answer: no
Explanation:
It could be dangerous since you don't know what substance are you adding.it may end up in an explosion
I hope this helps :)
