C) The atom must contain some centrally located positive charge. He called this core of positive charge the nucleus.
Explanation:
Rutherford concluded from his experiment that the atom contains some centrally located positive charge. He called the core the nucleus.
Rutherford developed the nuclear model of the atom.
- In a bid to explain his observation, Rutherford suggested the nuclear model.
- The model consists of small positively charged center called the nucleus.
- Nearly all the mass is concentrated in the nucleus.
- The extranuclear space is made up of electrons orbiting the nucleus.

Answer:
True
Explanation:
When a theory is proven over and over it will become a law
Mass and atoms are the properties conserved in every ordinary chemical reaction.
Hope this helps!
The molar solubility is 7.4× M and the solubility is 7.4× g/L .
Calculation ,
The dissociation of silver bromide is given as ,
→ +
S
- S S
Ksp = [ ] [ ] = [S] [ S ] =
S = √ Ksp = √ 5. 5× = 7.4×
The solubility =7.4× g/L
The molar solubility is the solubility of one mole of the substance.
Since , one mole of is dissociates and form one mole of each and ion . So, solubility is equal to molar solubility but unit is different.
Molar solubility = 7.4× mol/L = 7.4× M
