<u>Answer:</u> The parent isotope is undergoing alpha decay.
<u>Explanation:</u>
A nuclear reaction is defined as the reaction in which the changes in the nucleus of an atom take place and usually form a different element. An unstable nucleus undergoes various decay processes to attain stability.
Alpha decay is a type of decay process that happens when a heavy nucleus decays into a light nucleus with the release of an alpha particle. This alpha particle carries a charge of +2 units and has a mass of 4 units. It is also known as the helium nucleus. The general equation for this decay process is:
It is given that the daughter isotope formed has atomic number 2 less than the parent isotope. Thus, it is undergoing alpha decay.
Answer:
im getting 331.23
Explanation:
Element Number Mass Percet Composition
O 6 16.00 28.9828819853274
N 2 14.01 8.45937867946744
Pb 1 207.21 62.5577393352051
That would be <span>Q=mcΔt</span>t
m=0.358kg=358g
c=0.0920 cal/g deg C
<span>Δt</span><span>=60-23=37 deg C
Q=358*0.0920*37=1218 cal</span>
