Helpppppppp neededddd
ozzi

Answer:

Adam

Step-by-step explanation:

Speed is calculated with the formula distance over time.

Convert all measurements to the same unit: ft/s.

<u>Speed of Frank:</u>

d/t

=11/s

<u>Speed of Emily:</u>

d/t

=86/10

=8.6/s

<u>Speed of Adam: </u>

There are 5280 feet in a mile.

d/t

=5280/388

=13.6/s

<u>Speed of Noah:</u>

There are 60 seconds in a minute.

d/t

=600/60

=10/s

Adam runs the fastest because 13.6 > 11 > 10 > 8.6.

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!
