nata0808 [166]
<span>Uranium-236 is intermediate nuclei. created by fusion reactions an unstable isotope of uranium created from four hydrogen atoms used in the H-bomb.

Following is the reaction involved in above process:

</span>^{235}U+ ^{1}n →  ^{236}U→ ^{144}Ba + ^{89}Kr + 3 ^{1}n<span> + 177 MeV
</span>
Here, 
^{235}U = Fission material,
^{1}n = projectile,
^{236}U = intermediate nuclei,
^{144}Ba and ^{89}Kr = Fission product

ANSWER:

4 a) Specific elements have more than one oxidation state, demonstrating variable valency.

For example, the following transition metals demonstrate varied valence states: Fe^{2+}, Fe^{3+}, Cr^{2+}, Cr^{3+}, etc.

Normal metals such as Pb^{2+} and Pb^{4+} also show variable valencies. Certain non-metals are also found to show more than one valence state Pb^{3+} and Pb^{5+}.

4 b) Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons.

For example, Carbon-14 is a naturally occurring radioactive isotope of carbon, having six protons and eight neutrons in the nucleus. However, C-14 does not last forever and there will come a time when it loses its extra neutrons and becomes Carbon-12.

5 a) 2Fe + 3Cl_2 → 2FeCl_3    

5 b) 3Pb + 8HNO_3 → 3Pb (NO_3)_2 + 4H_2O + 2NO_2

5 c) Zn + H_2SO_4 → ZnSO_4 + H_2   (already balanced so don't need to change)

5 d) 2H_2 + O_2 → 2H_2O

5 e) 2Mg + 2HCl → 2MgCl + H_2

EXPLANATION (IF NEEDED):

1. Write out how many atoms of each element is on the left (reactant side) and right (product side) of the arrow.

2. Start multiplying each side accordingly to try to get atoms of the elements on both sides equal.
