HELP ASAP ALL THREE PLEASE 1. if a cyclic alkene has 12 carbon atoms, how many hydrogen atoms does it have 2.if a cyclic alkene
Marina CMI [18]

Answer:

1. 24

2. 6

3. No

Step-by-step explanation:

The formula for cyclic alkene is C^{n} H^{2n}, so if it has 12 carbon atoms, it will have double the amount of hydrogen atoms, therefore, 24 hydrogen atoms.

The same works in reverse. If we have 12 hydrogen atoms in this, then there will be half the amount of carbon atoms, therefore 6.

Since the relationship between Carbon and Hydrogen here is double and half, odd numbers can't be divided by 2 and end up with a whole number, so an odd number of hydrogen atoms is not possible.

Hope this helped!

What is the x-intercept of the equation -7x+3y=21
mezya [45]
Hello!!

Well, the x-intercept is found when y = 0, so plug in y = 0:

-7x + 3(0) = 21
-7x = 21
x = -3

Therefore, the x-intercept of -7x + 3y = 21 is -3.

Hope this helps!! Let me know if you have ANY questions.
