Answer:
pOH = 10.16
Explanation:
pOH is a measurement in chemistry that could be obtained with the equation:
<em>pOH = 14 - pH</em>
<em />
The mathematical definition of the pOH is:
pOH = -log [OH⁻]
If the pH of the solution is 3.84, the pOH is:
pOH = 14 - 3.84
<h3>pOH = 10.16</h3>
Answer:
HCl
Explanation:
The best solvent for NaF is a polar liquid. The only liquid having a significant dipole moment among the options is HCl due to the large electro negativity difference between hydrogen and chlorine.
The polar solvent can interact with the NaF via its dipoles such that the NaF dissolves due to ion-dipole interaction.
Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.
The ice sculpture would take longer to melt than the ice cube
Over the ocean, the temperature rises much slower, because the water evaporates causing the hot molecules to go into the atmosphere, and the overall temperature of the water doesn't increase much, this causes the area without the water to be much hotter.
