<h3><u>Answer;</u></h3>
Potassium chloride
<h3><u>Explanation;</u></h3>
- Potassium Chloride is an ionic compound and has ionic bond which is stronger than covalent bond in ethyl alcohol,water ,ammonia, and thus has the highest boiling point .
- ionic bond is a type of bond that results from the transfer of electrons between metallic atoms and non-metallic atoms.
Answer:
Clockwise
Explanation:
All of the planets rotate the same way around the sun.
<span>Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection.
</span>Diffuse reflection<span> is when light hits an object and reflects in lots of different directions. This happens when the surface is rough. Most of the things we see are because light from a source has reflected off it.</span>
The shortest visible wavelength is the last color you can see
at the blue end of the spectrum.
The light-gathering capacity of a telescope depends on the area
of the main lens in the front, or the main mirror in the back.
That's also the area of the opening of the tube, called the 'aperture'.
