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.
Answer:
<u>Convection</u>
Explanation:
<u>Convection definition</u>:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Answer:
to build a house you need land and people
Explanation:
8.25 grams of O2 has 0.258 moles of Oxygen. Here's how you figure that out:
Oxygen is one of the 7 diatomic elements, so it is normally O2.
<span>You find it's molar mass (or mass for </span>one mole<span> of it) by adding up two of the masses from the Periodic Table.</span>
Angstroms 1.0 x 10^-10 meters, nanometer 1.0 x 10^-9 meters, and picometer 1.0 x 10^-12 meters.
