RideAnS [48]2 years ago
4 0

Answer:

The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).

If I add 475mL of water to 75.0mL of a 0.315M NaOH solution, what will the molarity of the diluted solution be?
pantera1 [17]
Answer is: <span>the molarity of the diluted solution 0,043 M.
</span>V(NaOH) = 75 mL ÷ 1000 mL/L = 0,075 L.
c(NaOH) = 0,315 M = 0,315 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 0,075 L · 0,315 mol/L.
n(NaOH) = 0,023625 mol.
V(solution) = 0,475 L + 0,75 L.
c(solution) = 0,023625 mol ÷ 0,550 L.
c(solution) = 0,043 mol/L.

In solid NaCl, each sodium ion is surrounded by six chlorine ions and each chlorine ion is surrounded by six sodium ions. This a
kow [346]

Owing to the arrangement of ions in NaCl, the structure has a high melting point and crystalline structure.

Ionic compounds are know to have a crystalline structure. This is because the ions in the compound are arranged into a crystal lattice. A crystal lattice gives a regular repeating structure of ions in the crystal.

As a result of this order in the crystal, the resultant sodium chloride structure has a high melting point and crystalline structure.

PLEASE HELP WITH THESE TWO QUESTIONS
adelina 88 [10]

1. Q=112.8 kJ

2. Q=5.01 kJ

<h3>Further explanation</h3>

The heat required for phase change :

  • melting/freezing :

Q = mLf

Lf=latent heat of fusion

  • vaporization/condensation

Q = mLv

Lv=latent heat of vaporization

1.

m=50 g=0.05 kg

Lv (water) = 2256 kJ/kg

\tt Q=0.05\times 2256=112.8~kJ

2.

m=15 g=0.015 kg

Lf for water = 334 kj/kg

\tt Q=0.015\times 334=5.01~kJ
