What property of a solution remains the same after it is diluted?
sineoko [7]
The property of a solution which remain the same after it is diluted is THE AMOUNT OF SOLUTE.
Dilution is the process of adding solvent to a solution. This action decreases the concentration of the solute in the solution. When a solution is diluted, the amount of solvent increase, the total volume increases, the concentration decreases, but the amount of solute stays the same.

How many electrons in an atom can have each of the following quantum number or sublevel designations?
Karo-lina-s [1.5K]

Answer: (a) 2 (b) 6 (c) 14

Explanation:

In the Azimuthal quantum number(l) electrons in a particular subshell (such as s, p, d, or f) are defined by values of l (0, 1, 2, or 3).

s is l=0, p is l=1, d is l=2, f is l=3.

The magnetic quantum number (ml)  The value of ml can range from -l to +l, including zero. Thus the s, p, d, and f subshells contain 1, 3, 5, and 7 orbitals each, with values of m within the ranges 0, ±1, ±2, ±3 respectively. Each shell can have 2 x l + 1 sublevels, and each of these sublevel can accommodate up to two electrons.

(a) n=2, l=1, ml=0. If l=1 then 2 x 1+ 1=3 sublevels, 3*2=6 electrons. When l=1, ml =-1,0,+1, ml=0  accommodate two(2)electrons

(b) 5p. p is l=1  If l=1 then 2 x 1+ 1=3 sublevels, 3*2= electrons. This means in the 5 shell, the p orbital has 3 subshell and accommodate 6 electrons.

(c) n = 4, l = 3 if l=3 then 2 x 3+ 1=7 sublevel 7*2=14 electrons. This means the in the 4 shell, the f orbital has 7 subshell and accomdate 14 elections.

Wax is a nonpolar substance, but the surface of a piece of glass is polar. Based on your observations from part E, which substan
KIM [24]

Based on the observations from, the substance that water is more attracted to are polar substances.

<h3>What is the Polarity of water?</h3>

Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.

Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.

Since water molecules are polar, they are more attracted to molecules that are also polar.

Thus, based on the observations from, the substance that water is more attracted to are polar substances.
