Answer:Alkanes: CnH2n+2
n=8 --> C8H18. So it is 18 atoms
Step-by-step explanation:
Half of 126 is 63 because 63+63=126 and 126/2=63
-2/3x+3/7=1/2
-2/3x=13/14. Multiply by -2 to get positive
(-2). (-2) and whole number for x
3x=-26/14 or -13/7 [ -13/7_ 3 = -13/7 *1/3 =
Divide by 3 13/21
x=13/21
To solve this problem you must apply the proccedure shown below:
1. You have the following expression:
<span>(5s/s^2-10s+25) - (25/s^2-10s+25)
2. As you can see, they have the same denominator, therefore, you can rewrite it as below:
(5s-25)/</span> (25/s^2-10s+25)
3. When you factor ir, you obtain:
5(s-25)/(s-5)(s-5)
3. Simplifying:
5/(s-5)
Answer:
7.534g ring is heavier, by 2.234g
Step-by-step explanation:
Note: mg =
From here we can see Ring A (7.534g) is heavier than Ring B(5,300mg)
Difference in Mass = 7.534g - 5.3g
= 2.234g
