Uranium is a metallic element that is used in nuclear reactors and nuclear weapons. The vast majority of uranium found on Earth

is in the form of uranium-238, an isotope with a mass number of 238, while the uranium that is used for nuclear reactors and weapons is uranium-235, an isotope with a mass number of 235.
In a certain type of nuclear reactor, uranium-238 can be converted to plutonium-239, another radioactive element (with an atomic number of 94) that can be used to power nuclear reactions. Which of the following statements regarding uranium-238 and plutonium-239 is false?

An atom of plutonium-239 contains 145 neutrons.
An atom of plutonium-239 contains two more protons and one fewer neutron than an atom of uranium-238.
An atom of uranium-238 has a smaller mass than an atom of plutonium-239.
An atom of plutonium-239 contains one more proton than an atom of uranium-238.

If brine shrimp eggs were transported on shorebirds feet from a hyper saline lake into a less salty one
blagie [28]
<span> If the Brine Shrimp eggs were transported from a hyper saline lake from a less salty like, they would most likely go into their dormant state and become cyst-like since they are adapted to the salinity levels of their previous environment. In turn, they would not be able to hatch, and then later on, reproduce, in order to expand their population and continue their species. </span>

how do you identify a pure metal if you have a balance of a graduated cylinder and a table of densities for metals?
sattari [20]
We determine the mass of the metal in grams by weighing it using the balance. Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way: 1.measure amount of water in the graduated cylinder. 2. Place metal into the graduated cylinder 3. Measure the amount of water in the graduated cylinder 4. Subtract step 1 from step 3. The difference is the metal's volume. Once we have found out the mass and the volume then we calculate the density using the formula: Density = Mass/Volume. We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.
