Uranium-235 would be more useful for dating in Cambrian time because Cambrian time was 540 million years ago while the half life of carbon-14 is only 5,730 years
Hope this helps
I think it is B silicon and iron.
Explanation:
According to the law of dilution,
The given data is as follows.
= 0.4782,
= ?
= 0.025
,
= 250 mL
Hence, we will calculate the value of
as follows.
=
= 13.07
Thus, we can conclude that we need 13.07 mL 0.4782 M sodium thiosulfate solution using pipette.
