The nuclear disintegration series of 238-U is the source of radon-222 in soil.
<h3>What is nuclear disintegration ?</h3>
- The process of nuclear disintegration is how an unstable atomic nucleus loses energy through radiation.
- A substance that has unstable nuclei is regarded as radioactive.
- Alpha, beta, and gamma decay are three of the most prevalent types of decay, and they all entail the emission of one or more particles.
- Ionizing radiation offers a health concern by destroying tissue and the DNA in genes because it can damage the atoms in living things.
- Alpha particles may be present in the ionising radiation that is released.
- As one atom transforms into another, radioactive decay involves the emission of a particle and/or energy.
- Helium ions are released from an atom's nucleus during alpha decay. A neutron in the nucleus is converted to a proton and electron during beta decay.

Answer: For your first question about the book, the answer is 6 g/cm^3. For the ball, your mass is 50 grams.
Explanation: density = mass/volume; for example: your book was 1,800 g. Divide that by 300 cm^3 to get 6g/cm^3. For the ball, mass = density*volume, so you need to multiply .250 by 200 cm^3
A. Snails and crayfish would not survive in Birch Lake at a pH of 6.2.
B. Once they die out, the walleye will disappear as well.
Walleye: pH 6.0 — pH 9.0
Crayfish: pH 6.5 — pH 8.0
Snails: pH 6.4 — pH 8.0
At pH = 7.3, all three can survive.
At pH = 6.2, snails and crayfish will die out.
Then, the walleye will disappear because <em>their food supply has vanished</em>.
Animals and Plants won't have a place to live, get food and resourses. Some organisms won't have anyshelter, because some live in the water.
