Answer: Artificial transmutation may occur in machinery that has enough energy to cause changes in the nuclear structure of the elements. This releases, on average, 3 neutrons and a large amount of energy. The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted.
Hope this helped!!

Answer:
Options A, C and D.
Explanation:
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. It is represented by an increase in the oxidation number.
Reduction is the loss of electrons during a reaction by a molecule, atom or ion. It is represented by a decrease in the oxidation number.
Both processes makes up what we know as Redox (REDuction - OXidation) reactions.
Note: The oxidation number of an element in its ground state is 0.
To identify which reactions are redox, we look out for change in oxidation number of the molecule, atom or ions involved.
A) Al has an increase in oxidation number for 0 (reactant side) to +3 (product side), Silver moves from +1(reactant) to 0 (product side). this means Al was oxidized and Ag+ was reduced. This is a redox reaction.
B) All atoms involved retains their oxidation number. S= +6, O =-2, H =+1. This is not a redox reaction.
C) Ba has an increase in oxidation number form 0 to +2, while Cl has a decrease in oxidation number form 0 to -2. This is a redox reaction.
D) Mg has an increase in oxidation number form 0 to +2, while Br has a decrease in oxidation number form 0 to -2. This is a redox reaction.
Answer:
temporary is only for specific amount of time and permanent is suppost to mean forever
Explanation:
all i can say is not much can be permanent
Answer: 36.3 ml
Explanation:
According to the neutralization law,
where,
= basicity = 2
= molarity of solution = 0.51 M
= volume of solution = ?
= acidity of = 1
= molarity of solution = 0.36 M
= volume of solution = 103 ml
Putting in the values we get:
Therefore, volume of required is 36.3 ml
Answer:
D
Explanation:
we use noble gas configuration of Kr because Kr atomic number is nearest to Sr
the atomic number of Kr and Sr
is equal to 36 and 38 based on this we write the electron configuration
1s2 ,2s2 , 2p6 , 3s2 , 3p6 , 4s2 , 3d10 , 4p6 === Kr and 5s2
