i think the answer is C because it take a Molecular form so im certain the correct answer is c
Answer:
C.
Explanation:
Objects and liquids float on liquids of a higher density and sink through liquids of lower density. the water and corn starch sank under the oil as well so that means they are denser. The paper clip sank through all three liquids also. Hence, the answer would be the clip is denser than the three liquids, and water is denser than oil.
Answer:
6.70 g
Explanation:
A common formula for determining the amount of sample remaining in terms of its half-life is
![N =N_{0}(\frac{ 1}{2 })^{n}](https://tex.z-dn.net/?f=N%20%3DN_%7B0%7D%28%5Cfrac%7B%201%7D%7B2%20%7D%29%5E%7Bn%7D)
where
![n = \frac{t }{t_{\frac{1 }{2 }} }](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7Bt%20%7D%7Bt_%7B%5Cfrac%7B1%20%7D%7B2%20%7D%7D%20%7D)
t = 458 000 yr
Calculate n
n = 458 000/229 000
n = 2.000
===============
N = 1.675 g Calculate N₀
![1.675 = N_{0}(\frac{ 1}{2 })^{2.000}](https://tex.z-dn.net/?f=1.675%20%3D%20N_%7B0%7D%28%5Cfrac%7B%201%7D%7B2%20%7D%29%5E%7B2.000%7D)
1.675 = N₀ × 0.2500 Divide by 0.2500 and transpose
N₀ = 1.675/0.2500
N₀ = 6.70 g
