C-C bonds = 348 C=C bonds = 614 C(triple) bonds = 839
All in KJ/Mol
just do 839-614=225 and 614-348=266
After a pi bond is added on, these two numbers are the KJ/Mol it takes to separate the C-C bond,
To get the average: (225+266)/2 = 245.5Kj/Mol
You might want to round your answer to 246KJ/Mol
Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let 
denote the number of rafts seating 3 people and 
the number of rafts seating 5 people. The total number of rafts is 13, so 
. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so 
.
It's always a good idea to put these equations under each other:
We can subtract the first equation three times from the second one to obtain 
Now, substitute this found value for into 
and we see that 
. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Answer: 12.5%
Step-by-step explanation:
80x 12.5%=10
80+10=90
Answer:
the answer is m = 3 or m = -2
Step-by-step explanation:
Answer:
x=-5
Distribute
Subtract 9 from both sides.
Divide both sides by 3.
