Common sense tells me that it is asthma cause i have it and yeah good luck
Alkali metals have the lowest electronegativities, while halogens have the highest.
The number of bacteria is given by:
N(t) = N(o) x 2ⁿ
Where N(t) is the number after n hours have passed and N(o) is the original number which is 15.
The number grown in the 12th hour is the difference in the number after the 11th and the 12th hour. Thus:
15 x 2¹² - 15 x 2¹¹
= 30,720 bacteria
Your final answer is that you will need 52.9mL of the 8.20 M of LiCl
