how does the kinetic energy of a substance's particle in the solid phase compare to their kinetic enegy in the liquid phase?​
iVinArrow [24]
The kinetic energy in the solid and liquid phases is the same. The kinetic energy of the substance's particles will depend on the volume of the substance. The particles have less kinetic energy in the liquid phase than they do in the gas phase. ... They vibrate so quickly that the particles ionize and become plasma.

How many milliliters of a stock solution of 2.00M KNO3 would you need to prepare 150mL of a 0.3M solution?
ser-zykov [4K]

Answer:

The answer is "22.5"

Explanation:

Concentration:

M_1= 0.3 \ m \ of\ KNO_3\\\\M_2=2.00\ M\\\\  

Volume:

V_1=150 \ ml \ of\  KNO_3 \\\\V_2=?

Using formula:

M_1V_2=M_2V_2\\\\V_2=\frac{M_1V_1}{M_2}\\\\

    =\frac{0.3 \times 150}{2}\\\\=\frac{45}{2}\\\\=22.5
