sodium has a lower electronegativity:)
Explanation:
Answer:
a drought !
- little to no water causes it
- it causes for organisms to die and organisms need water !
The formula of determining the
value is:

where both the distance are measured from the common origin.
10 % ethyl acetate/ hexane means it has 10 % ethyl acetate and 90 % hexane which are non-polar in nature. Hence, the non-polar compound will travel farther in the TLC plate along with the eluent and the polar compound will travel less as they remain attracted to the polar adsorbent
.
Among 3-decanone and 3-decanol, 3-decanone will have high
as it is non-polar.
Among toluene and benzoic acid, toluene will have high
as it is non-polar.
Among cyclooctane and cyclooctanone, cyclooctane will have high
as it is non-polar.
Answer:
8.73
Explanation:
when you are adding or subtracting numbers, the sigfig (significant figure) is based on how many numbers after the decimal. with this info, we can see that 15.67 has 2 sigfigs and 6.943 has 3 sigfigs. when you subtract normally, you would get 8.727, which has 3 sigfigs, so you would round the last 7 up to get 8.73 with 2 sigfigs!
also it is to 2 sigfigs because we know that we go by the least number of sigfigs. hope this helped!
