Answer:
Xenon- 131
Explanation:
Iodine- 131 ------------------> Xenon -131 + Beta particle
Explanation:
Noble gases are group O elements and their atomic structure ensures that they are stable. All their orbitals are completely filled with electrons therefore they do not undergo reactions with other elements.
- Heavier noble gases are able to form a range of compounds due their sizes.
- Elements form compounds by exchanging or sharing of their outermost shell electrons called the valence electron.
- Every atom has specific energy required to remove electrons from them. The energy is known as the ionization energy.
- In bigger atoms which have large radius, the outermost electrons have low ionization energy which makes them easy to remove.
- The ionization energy depends on the nuclear charge, the more the charge the higher the ionization energy. Down a group the nuclear charge and ionization decreases.
- As we go down the inert group, the ionization energy of outer shell electrons become very low. This makes the electrons available to take part in chemical reactions.

There are 4 different products will be formed from a poorly planned crossed aldol addition.
In a crossed aldol condensation, two distinct ketone and aldehyde reactants are used. Due to the possibility of several enolate nucleophiles as well as multiple carbonyl electrophiles, similar reactions typically result in a variety of distinct condensation products.
Ethanol and propanol undergo cross-aldol condensation, which results in two products:
- one where ethanol serves as an enolate ion and the other where propanol serves as an enolate ion.
- 2-Methylbut-2-enal and Pent-2-enal are just the two cross-aldol derivatives.
Therefore, the correct answer will be option (d)

Answer:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
Explanation:
Iron is a metallic element with chemical symbol, Fe while concentrated sulphuric acid is a chemical compound with chemical formula, H2SO4. Both are involved in a chemical reaction as follows:
Fe + H2SO4 → Fe2(SO4)3 + H2
However, this reaction is not balanced as the number of moles of each atom in both the reactants and product side is not equal. To balance the equation, we have to ensure that each number of atom is equal. The balanced equation are as follows:
2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2
