Which statement best describes the properties of sodium chloride?A.) Sodium chloride is a malleable solid.
B.) Solid sodium chloride is a good conductor of electric current.
C.) Sodium chloride has a low melting point.
D.) Liquid sodium chloride is a good conductor of electric current.

Answers

Answer 1
Answer:

NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.c Thus, option D is correct.

What best describes the properties of sodium chloride?

The ions (Na+& Cl) are free to move around and can thus function as charge carriers, since the motility of individual atoms or molecules in liquid state is significantly larger than that of solid state. Because of the free ions, molten sodium chloride is a good conductor of electricity.

The charged particles (ions) in solid “[NaCl]” cannot move because they are bound by powerful electrostatic forces, making it a poor conductor of electricity. They cannot conduct electricity as a result.

Therefore, NaCl solutions are electrically conductive because they are a powerful electrolyte in which the constituent ions completely separate, resulting in free-moving ions in the solution.

Answer 2
Answer:

D. because sodium chloride is an ion

first of all , sodium chloride is salt and  we all know that it is not malleable.

sodium chloride is an ion which do conduct electricity but not when they are solid.....they only do so when they are molten or aqueous ( dissolved in water )

sodium chloride is an ion. ions have high melting points.

D is true because as i have mentioned above , ions will conduct electricity when dissolved in water / aqueous or molten.......... HOPE IT HELPED !!!!!!

What is the acceleration of a vehicle that goes from 70 m/s to a stop in 35 s?

Answers

u=70 , v= 0, t=35, a=?
v=u+at
0=70+a(35)
-70=35a
a=-2m/s^2
Decelerate 2ms^-2 or acceleration is -2ms^-2

Why does the sun change colors at sunset

Answers

The reason that the sun changes colors at sunset is because small particles and molecules in the atmosphere change the direction of light ray causing them to scatter and resulting in a beautiful sunset.

What is the average acceleration of a jet ski that goes from rest to 10 m/s west in 4 s? Take the direction west to be positive, and east to be negative. A.
2.5 m/s2

B.
-2.5 m/s2

C.
0.4 m/s2

D.
-0.4 m/s2 PLZZZ HELP ASAP!

Answers


|acceleration| = (change in speed) / (time for the change)

                       = (10 m/s - 0)          /  (4 s)

                       =        (10 / 4) (m/s²)

                       =            2.5 m/s² .

The direction of the acceleration is west.
