Dubnium-262 has a half-life of 34 s. How long will it take for 500.0 grams to

dmitriy555 [2]

Answer:

the time taken for the radioactive element to decay to 1 g is 304.8 s.

Step-by-step explanation:

Given;

half-life of the given Dubnium = 34 s

initial mass of the given Dubnium, m₀ = 500 grams

final mass of the element, mf = 1 g

The time taken for the radioactive element to decay to its final mass is calculated as follows;

$1 = 500 (0.5)^{\frac{t}{34}} \\\\\frac{1}{500} = (0.5)^{\frac{t}{34}}\\\\log(\frac{1}{500}) = log [(0.5)^{\frac{t}{34}}]\\\\log(\frac{1}{500}) = \frac{t}{34} log(0.5)\\\\-2.699 = \frac{t}{34} (-0.301)\\\\t = \frac{2.699 \times 34}{0.301} \\\\t = 304.8 \ s$

Therefore, the time taken for the radioactive element to decay to 1 g is 304.8 s.

Line m passes through the points (2, -7) and (4, -9) line m is parallel to which line

zhannawk [14.2K]

Answer:

The Answer is: The slope is -1, so any line with the same slope is parallel.

Step-by-step explanation:

Given points (2, -7) and (4, -9) find the slope, m:

m = y - y1 / (x - x1)

m = -7 - (-9)/(2 - 4)

m = -7 + 9/-2

m = 2/-2

m = -1

A parallel line is any line with the same slope which is -1.

Hope this helps! Have an Awesome day!! :-)
