Answer:
Los metales alcalinotérreos son casi estables, pues si pierden dos electrones tendrán una configuración bien estable. ... Dicho de otro modo, a menos que indique lo contrario, las generalidades de los metales alcalinotérreos estarán referidas para todos los elementos del grupo 2 MENOS el berilio y el radio.
Explanation:
C. 115 is your best answer
There are 118 elements in the Periodic Table
hope this helps
Ksp of AgCl= 1.6×10⁻¹⁰
AgCl=Ag⁺ +Cl⁻
Ksp=[Ag⁺][Cl⁻]
Assume [Ag⁺]=[Cl⁻]=x
Ksp=x²
1.6×10⁻¹⁰=x²
x=0.000012
In FeCl₃:
FeCl₃------>Fe⁺³+ 3Cl⁻
as there is 0.010 M FeCl₃
So there will be ,
[Cl⁻]= 0.030
So
[Ag⁺]=Ksp/[Cl⁻]
=1.6×10⁻¹⁰/0.030
=5.3×10⁻⁹
so solubility of AgCl in FeCl₃ will be 5.3×10⁻⁹.
Answer:Sunlight travels through space without the aid of fluids or solids
Explanation: Radiation involves transfer of energy or heat with the help of electromagnetic waves.
For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.
Density = Mass / Volume
Density = 2.0g / 5.0ml
Density = 0.4 g/ml
