Answer:
10.875 miles
So 87 minutes
.125 miles per minute
So just multiply int his case
87*.125
You’d get 10.875
Answer:
How many moles of Cl– ions are in 2.20 L of 1.50
The amount remaining at the end of 5 half-lives is 7.81×10¹³ g
From the question given above, the following data were obtained:
- Half-life (t½) = 5730 years
- Original amount (N₀) = 2.5×10¹⁵ g
- Number of half-lives (n) = 5
- Amount remaining (N) =?
The amount remaining can be obtained as follow:
N = 1/2ⁿ × N₀
N = 1/2⁵ × 2.5×10¹⁵
N = 1/32 × 2.5×10¹⁵
N = 0.03125 × 2.5×10¹⁵
N = 7.81×10¹³ g
Therefore, the amount remaining after 5 half-lives is 7.81×10¹³ g

Answer:
studying chemicals containing carbon.
Explanation:
Pure chemistry can be regarded as
branch of science that's based on conduction of basic research so that
personal knowledge can be acquired. It can be reffered to as theoretical branch of chemistry, not applied branch. It comes with curiosity about something, how and why it happens. For instance, studying chemicals containing carbon is to gain knowledge there's no applied chemistry here
