Answer:
Precipitate
Explanation:
When a double displacement reaction occurs, the cations and anions switch partners, resulting in the formation of two new ionic compounds AD and CB, one of products is in the solid state and forms an insoluble ionic compound called a precipitate.
Any object having a temperature greater than absolute zero gives off electromagnetic radiation. Water in the atmosphere primarily known as water vapor upon encountered by the heat released by the sun emits relatively long wavelengths of infrared photons. These infrared photons moved up to the more elevated level in the atmosphere since it is now highly reactive.
The best way to arrange the salon to best use what he has is:
- Place the bulb in the middle of the wall
- Directly face the chair and mirror in front of the bulb for proper lighting and reflection
- Place the chairs side by side of each other
- Each mirror should be facing each chai
<h3>What is Reflection?</h3>
This refers to the change in direction of a wavefront between two different media so that the wavefront returns to its originating medium.
Hence, we can see that from our knowledge of shadows and reflection, we can note that mirrors reflect and light helps to bring detail in a dark area and the chairs should be facing the mirrors directly so the customer can see his hair and how it is being cut by the barber.
