Answer:
47, 68, 47
Explanation:
Let's consider the following isotope: ¹¹⁵Ag.
If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.
Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.
The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:
p⁺ + n⁰ = 115
n⁰ = 115 - p⁺ = 115 - 47 = 68
The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.
Answer:
I believe the answer is electrons.
Explanation:
Protons can't move and neurons don't have a charge so it would be electrons.
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure.
First you find moles of HCl.
8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl
Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
