Answer:
The decay of unstable atoms releases radiation, a phenomenon called radioactivity. As unstable atoms exist in all matter, we are surrounded by natural radiation. Radiation can also come from man-made sources, through military, medical or industrial applications.

Answer: The child isotope has an atomic mass of 206.
Explanation:
Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.
General representation of an element is given as:
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
General representation of alpha decay :
Answer
Option D
When a grignard Reagent reacts with Ethylene Oxide... A Primary Alcohol is Formed.
CH2OCH2 + RMgX ==> RCH2CH2OMgX
When You Hydrolyze
You have
RCH2CH2OH
The Text written below may come in handy someday.
Hope you find it helpful.
One of the preparation of Alcohols is via Reaction with "Grignard Reagents" .
Grignard Reagents have the formula "RMgX"
Where R is an alkyl group eg CH₃, C₂H₅ etc
X is a halogen eg Cl,Br etc
Ethylmagnesiumbromide fits the description of grignard Reagent from what I wrote above.
The formula for Ethylmagnesiumbromide is
"C₂H₅MgBr"
Now
When grignard reagents react with Alkanals... They form alcohols.
Note this trend.
When a grignard reagent reacts with Methanal(Formaldehyde)... It forms a Primary Alcohol.
When a grignard reagent reacts with any other Alkanal besides Methanal(formaldehyde) ... it forms Secondary Alcohols.
We solve for the number of mols of CO2 given its volume, assuming that it is an ideal gas.
n = PV / RT
Substituting,
n = (1 atm)(15.67 L) / (0.082 L.atm/mol.K)(273.15 K) = 0.7 moles
From the balanced chemical reaction above, we determine the number of O2 moles needed to produce 0.7 moles CO2.
0.7 moles CO2 x (3 moles O2/ 2 moles CO2) = 1.05 moles O2
Then, we multiply this value by 22.4 L/mol
1.05 moles O2 x (22.4 L / mol) = 23.52 L O2
Thus, the answer is the fourth choice.
