Answer:Discuss experiments that led to discovery of the electron and the nucleus ... These particles had a similar mass as protons, but did not have the same ... The atomic nucleus contains a mix of positively charged protons and ... Intro to the History of Atomic Theory – Intro: Rutherford, Thomson, electrons, nuclei, and plums.
Explanation:
Answer: 14.01 moles
To solve this question, you need to determine the molecular mass of the Ba(OH)2. The molecular mass would be: 137.3 + 2(16+1)= 171.3g/mol.
If the total weight of Ba(OH)2 is 2400g and its molecular mass is 171.3g/mol, the number of moles would be: 2400g/ (171.3g/mol)=14.01 moles
Answer:
6.47 M (3 s.f.)

C:
Explanation:
March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect.
Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.
Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.
→ 
It can be seen that after the beta minus decay Fe changes into Co.
In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.
Neutron-rich nuclei often decay by producing both an electron and an antineutrino.
Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.
