Answer:
Alpha particle or helium nuclei.
Explanation:
Alpha particle:
Alpha particle is emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
In areas where resistance is present, otherantimalarials<span>, such as </span>mefloquine<span> or atovaquone, may be used instead. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations.</span>
HCl is NOT an organic molecule.
It contains <em>no carbon</em>.
All the other compounds are organic because they contain both C and H.
Answer:
Loose Material is compacted by pressure.
