I’m gonna give answers that I’m only 100% sure of, and maybe suggest answers too

9. Neutrons
10. Protons and Neutrons
12. Atomic Mass / Mass Number
13. Little Boy over Hiroshima, Japan.
14. Spontaneous fission
15. Alpha decay
17. Marie Curie
19. Nuclear fission
20. Gamma rays
21. Atomic number

I’d probably know more of these if I paid attention more in my lessons/studies IMO, but here’s what I know 100% for those answers!

Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) P₄(s) → HPO₃²⁻(aq) + PH₃(g) [acidic]
m_a_m_a [10]

The balanced chemical equation is :

5P₄ + 36OH → 12HPO₃⁻² (aq) + 8PH₃ (acidic)

Here the oxidation number of P changed from 0 to -3 in PH₃ and increases  from 0 to +3 in HPO₃⁻². When P₄ changes to PH₃ reduction reaction is taking place as there is addition of hydrogen and when P₄ changes to HPO₃⁻² oxidation takes place as there is addition of oxygen.

Thus clearly both reduction and oxidation are taking place.

Thus, we can infer that here P₄ is both oxidizing as well as reducing agent.

Consider the balanced chemical equation: 2o3(g) → 3o2(g). how many moles of o2 are produced when 0.50 mol of o3(g) reacts
kiruha [24]
   2O3→3O2
 The  number  of moles of O2  that  are   produced  when 0.50  moles  of O3(g)  reacted is  0.75  moles

  calculation and explanation

   2  moles    of O3(ozone)  react  to give   3 moles of O2  (oxygen  gas,therefore the reacting   ratio  between O3 :O2 is  2:3

 
 if 0.50  moles of  O3  reacted  then,by use  of  reacting ratio (2:3)  find the moles of O2  produced

That is   0.50 x3/2  =  0.75   moles
