Answer:
fission
fusion
Explanation:
The two reactions shown are nuclear reactions. There are two main types of nuclear reactions;
1) fission reaction
2) fusion reaction
A fission reaction is said to have occurred when a large and unstable nuclide is bombarded with neutrons thereby causing it to decay into daughter nuclei.
A fusion reaction involves the combination of two light nuclei to yield a heavier nuclei.
In the first reaction, a neutron was used in bombarding a uranium nucleus to yield the products listed on the product side of the nuclear equation. We know this by comparing the sum of the masses and charges on the product side with those on the reactant side in order to decide what the bombarding particle is.
The second reaction involves the fusion of two deuterium nuclei to yield one helium nuclei and neutrons as shown.
To solve the problem, use the equation
M1(V1) = M2(V2)
Where M1, M2 are the concentrations
V1, V2 are the volumes
Given V1 = 30.0 mL, M1 = 12.0 M
M2 = 0.16 M
Substituting to the equation,
(30)(12) = (V2)(0.16)
V2 = 2250 mL
<u>Answer:</u> The half life of the given radioactive isotope is 43.86 minutes
<u>Explanation:</u>
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant = ?
t = time taken for decay process = 233 minutes
= initial amount of the reactant = 0.500 M
[A] = amount left after decay process = 0.0125 M
Putting values in above equation, we get:
The equation used to calculate half life for first order kinetics:
where,
= half-life of the reaction = ?
k = rate constant =
Putting values in above equation, we get:
Hence, the half life of the given radioactive isotope is 43.86 minutes
Answer:mol solute / L soln. M = 5.50 mol / .600 L. M = 9.16 molar
