Explanation:
i tried to answer the most because of my proofile page it seems like i am in high school but i am iin 6th grade
The peaks at 3300 cm-1 and 2200 cm-1 are due to terminal alkyne group (triple bond between two carbons) and triple bonded C-H stretching
So
The answer is : terminal alkyne
Another peak near 3430 cm-1 must be due to an -OH group
so the answer is : alcohol
Answer:
82 days would take a distance like that, if we drive at 120 mi/h
Explanation:
Distance from Earth to moon is 3.8×10⁵ km
You drive at a speed of 120 mi/h
Let's convert the 120 mi/h to km/h
1 mi = 1.61 km
Then 120 mi . 1.61 km / 1mi = 193.2 km
New velocity is 193.2 km. Therefore,
193.2 km are driven in 1 hour
3.8×10⁵ km woul be driven in (3.8×10⁵ . 1)/ 193.2 = 1966.8 hours
1967 hours . 1 day / 24 hours = 82 days
Simply its the smallest particle da
