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!

Which of the following compounds would be more soluble in 1 M NH3 than in pure water? BaSO 4 AgBr Pbl 2 BaF 2 Ca(OH) 2
Kazeer [188]

Answer:

AgBr

Explanation:

The salt, AgBr has a very low solubility is pure water. However, it has a high solubility in 1 M NH3. The reason behind this higher solubility of AgBr in 1 M aqueous ammonia solution is the formation of a complex as shown below;

AgBr(s) + 2NH3(aq) ----> [Ag(NH3)2]^+(aq) + Br^-(aq)

The formation of this linear silver diammine complex accounts for the higher solubility of AgBr in 1 M aqueous ammonia solution.

A sample of chlorine gas fills a vessel at a temperature of 37oC. The vessel has a volume of 3L and experiences a pressure of 3a
Iteru [2.4K]

Answer:

25.1 g is the mass of chlorine in the sample

Explanation:

P . V = n . R . T

We apply the Ideal Gases Law to solve the excersise.

We need to convert the T°C to T°K → 37°C + 273 = 310K

We replace data: 3 atm . 3L = n . 0.082 L.atm /mol.K . 310K

9 atm.L / (0.082 L.atm /mol.K . 310K) = n → 0.354 moles

We convert the moles to mass, to reach the answer

0.345 mol . 70.9g / 1mol = 25.1 g
