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:]
Las propiedades de la materia incluyen cualquier rasgo que se pueda medir, como la densidad, el color, la masa, el volumen, la longitud, la maleabilidad, el punto de fusión, la dureza, el olor, la temperatura y más de un objeto
Answer:
2.5 Hz
Explanation:
Formula for the given question is:
Velocity= frequency X Wavelength.
v= f X λ.
25 = 10 X f
f= 2.5 Hz
Answer: B
Explanation: It makes the most sense to me as the way temperature is measured, is with 0 degrees Celsius as the standard and 1 atm for pressure, if I am incorrect for any reason, please let me know
Answer:
10 C-8/5 - 16 e- → 10 C0 (oxidation)
16 Cl0 + 16 e- → 16 Cl-I (reduction)
