Answer:
It has two isomers; n-butane and isobutane. Here n-butane is a straight-chain compound with four carbon atoms bonded with single covalent bonds. Explanation: Butane is an alkane with four carbon atoms so molecular formula is C4H10.
Explanation:
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15
Answer:
Explanation:
Given : Sample size : n= 30 , it means it is a large sample (n≥ 30), so we use z-test .
Significance level :
Critical value:
Sample mean :
Standard deviation :
The formula to find the confidence interval is given by :-
i.e.
i.e.
Hence, the 95% confidence interval for the mean mpg in the entire population of that car model =
Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
