The alpha decay of Radon-198 produces alpha particle and ¹⁹⁴₈₄Po.
Alpha decay is a type of radioactive disintegration in which some unstable atomic nuclei spontaneously expel an alpha particle to dissipate excess energy.
Alpha decay of Radon-198 is shown as:
¹⁹⁸₈₆Rn → ⁴₂He + ¹⁹⁴₈₄Po
In the above decay from the parent nuclei, daughter nuclei (¹⁹⁴₈₄Po) and alpha particle (⁴₂He) is produced.
Hence daughter nuclei of the alpha decay of Radon-198 is ¹⁹⁴₈₄Po.

it would be 0.75 atm
What is the [H+] after the change?
Answer:
2
Explanation:
Answer: The chemical species formed in a chemical reaction are products.
Explanation:
In a chemical equation, the chemical species are called as reactants or products.
Reactants are defined as the chemical species that react in the reaction and are written on the left side of the reaction arrow.
Products are defined as the chemical species that are produced in the reaction and are written on the right side of the reaction arrow.
For Example: Formation of water from hydrogen and oxygen gases, the equation follows:
The chemical species are termed as reactants and is termed as products.
Hence, the chemical species formed in a chemical reaction are products.
the answer is lavoiser
Antoine-Laurent de Lavoisier, a French chemist, organized elements into four groups based on their properties: gases, nonmetals, metals, and earths. This was a monumental contribution to the field of Chemistry.
The person you're referring to who organized elements into four groups based on their properties is the French chemist Antoine-Laurent de Lavoisier. Lavoisier is commonly known as the 'Father of Modern Chemistry' and his work contributed significantly to the development of this field. In the late 18th century, he sorted 33 elements into four categories: gases, nonmetals, metals, and earths, by recognizing their similar properties. This was a significant step at the time, further paving the way for the modern periodic table.
