Answer:
- <u>The container must be built of lead, and it should be kept in a concrete vault.</u>
Explanation:
The goal is to contain the <em>gamma rays</em> to<em> reduce</em> the <em>exposure </em>to their harmful <em>radiation</em>.
The gamma rays are the most energetic electromagnetic radiation: they have the smallest wavelength, the largest frequency, and the largest energy from all the electromagnetic radiations.
Due to that, only very dense substances like lead and concrete can stop the gamma rays. In the case of concrete, large blocks with thick walls are required.
Thus, in a lab the best container for a sample of uranium - 238 that is decaying, emitting gamma rays, must be built of lead, and enclosed in a conrete vault.
The ability of carbon atoms to form covalent bonds with other carbon atoms is the most unique of its bonding properties. CARBON can also accept electrons or share. Two main reasons why its unique. Hope this helps even though its been 5 days for you.
Answer:
Add is wires and lights.
Explanation:
Gas laws include the wire lines the produce temeperature and the lights system.
The pH unit has 10x as many hydrogens ions as the unit above.
Ex: A pH of 5 would have 10x more hydrogen ions than a pH of 6
and 100x more than if it had a pH of 7.
With a pH of 9 and 3, this is equivalent to 10⁶
So your answer should be:
1,000,000
