A nuclear reaction must lead to changes in the nucleus of an atom.
<h3>What is a nuclear reaction?</h3>
The term nuclear reaction refers to a reaction in which a new nucleus is formed. The following are the nuclear reactions;
a) 60/27Co -----> 60/28 Ni + 0/-1 e
b) 241/95 Am ------> 237/93Np + 4/2He
c) 60/29 ----> 60/28 Ni + 0/1 e
d) 66/31 Ga + 0/-1 e -----> 66/30 Zn

Answer:
Here are three examples
Explanation:
In a reversible reaction, the conversions of reactants to products and of products to reactants occur at the same time.
Example 1
The reaction of hydrogen and iodine to from hydrogen iodide.
H₂ + I₂ ⇌ 2HI
Example 2
The dissociation of carbonic acid in water to form hydronium and hydrogen carbonate ions
H₂CO₃ + H₂O ⇌ H₃O⁺ + HCO₃⁻
Example 3
The dissociation of dinitrogen tetroxide to nitrogen dioxide.
N₂O₄ ⇌ 2NO₂
Answer:
B.spiderman
Explanation:
DNA has been transferred to another species. Spiderman became Spiderman when DNA from a spider combined with a human.
You must remember that oxidation number of hydrogen in acids is always +1, oxidation number of oxygen in oxides & acids is always -2... metals has always oxidation number on plus!
group NO3 comes from HNO3...and oxidation number of whole acid group is always on minus and equal to the amount of hydrogen atoms in this acid... so oxidation number of NO3 = -1
we have 2 NO3 groups so 2*(-1) = -2 and that is the reason why oxidation number of Fe in this formula must be +2... because sum of all elements always gives 0!
Now we could count of oxidation number for nitrogen... we write HNO3 and start counting from right to left:
3*(-2) from oxygens + 1 from hydrogen = -5
so nitrogen must have +5 oxidation number... because sum all in formula must be 0.
