The two elements mixed together to form a chemical bond and reacted as a chemical change
Answer:
2.640
Explanation:
Rounding to the nearest whole number would be 3 if that is needed.
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 answer would be they have mobile ions in solution.
<span>D. all of the above because ionic compound is a salt. it is also held together by ionic bonds. it has anions and cations </span>
