Mass number is the total number of Protons and Neutrons. Simply subtract 85 from 210. 210-85=125 neutrons
Rutherford !
The so-called Rutherford experience consisted mainly of launch, against a gold plate, with a beam of particles emitted by a radioactive source. These particles whose electric charge is positive are known as alpha particles.
hope this helps!<span />
I think the correct answer from the choices listed above is the second option. The difference between speed and velocity would be that speed <span> requires distance. Velocity requires displacement. Speed only has a magnitude while velocity is a vector quantity which means it has direction and magnitude.</span>
Answer:they get it though food!
Explanation:
Answer:
b. .28 M KCI
Explanation:
Use the dilution formula.
C₁V₁ = C₂V₂
C₂ = C₁V₁/V₂
C₂ = 1.6*0.175 / 1.0
C₂ = 0.28
