In natural selection, the finches on the Galapagos Islands. The bug population greatly decreases, and only the finches with the strong beaks were able to survive as they could access the nut meats encased in hard shells. However, when a drought swept through the area, the trees didn't bear any nuts, and so the finches with the larger beaks died off and the finches with the slimmer beaks <span>survived as they could reach the bugs deep in the crevasses of the tree bark.

When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate int
PtichkaEL [24]

Answer:

The correct answer is C) 1 L of 1.0 M NaCl

Explanation:

NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:

A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.

C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).

The solution with the greatest solute particle number is C).
