For the discovery of the elements polonium and radium. Prohibited from higher education in her native Poland (then controlled by Russia), she moved to Paris in 1891 and studied at the Sorbonne.
Answer:
If an atom has the same number of electrons as protons, it is a neutral atom.
Explanation:
Answer:
D. 2.0 M CuCl2
Explanation:
The ionic strength of a solution shows the concentration of its ions in that given solution of the compound. Dissolved ionic compounds always dissociate into ions. The total amount of ions in solution will definitely affect the properties of the solution. The concept of ionic strength was first introduced by Lewis and Randall in 1921 while describing the activity coefficients of strong electrolytes.
The ionic strength of CuCl2 is 6M as shown:
ionic strength = 0.5*[(+2)^2*2M + (1-)^2*4M] = 6 M
The higher the ionic strength of a solution, the greater its non ideal behavior.
CuCl2 shows the greatest ionic strength hence the greatest non ideal behavior.
False..........
it has so many consequences
