When benzene reacts with CH3COCl in the presence of anhydrous AlCl3, Friedel-Crafts acylation occurs. The acylation reaction involves the substitution of a hydrogen atom on the benzene ring with an acyl group, resulting in the formation of an acylated benzene compound. This process is a way to introduce acyl groups onto aromatic rings.
When benzene reacts with CH3COCl in the presence of AlCl3, acetyl chloride gets attached to benzene ring to form acetophenone, a type of ketone compound. This reaction is an example of Friedel-Crafts acylation.
If you breathe out on cobalt chloride paper, the paper will turn pink due to the presence of moisture (water vapor) in your breath. Cobalt chloride paper is used as a moisture indicator and changes color in the presence of water.
Eruptions happen when pressure builds up beneath the Earth's surface, usually due to the movement of molten rock (magma) within the Earth's mantle. When this pressure becomes too great, the magma is forced to the surface, leading to an eruption. Volcanic eruptions can also be triggered by other factors, such as tectonic activity or the presence of gases within the magma.

If plate tectonics did not happen, the ocean floor would likely be smoother and more uniform, without the presence of mid-ocean ridges, trenches, and seismic activity caused by plate movements. Mountain ranges and underwater volcanoes associated with tectonic activity would also be absent.

Benzene
Exposure to benzene can cause Leukemia.
Giant explosion occurs leaving only the smell of burnt pubic hair.
Crystals may disappear during suction filtration of a sample crystallized from benzene if the crystals dissolve in the solvent being used for filtration, or if they break up into smaller particles that pass through the filter. This can happen if the crystals are not fully dried or if too much force is applied during filtration.
Rust is formed in metals when it exposed to oxygen and moisture in air and in the presence of acid.
microorganism like yeasts produce ethanol in presence of sweet conditions
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
The iodine will turn blue-black in the presence of starch due to the formation of a complex known as "iodine-starch complex." This color change is often used as a test for the presence of starch in a sample.
When iodine is dropped on cotyledons, it will turn blue or purple in the presence of starch. This color change indicates the presence of starch in the cotyledons. Starch is produced during photosynthesis by plants and stored in cotyledons as a source of energy for germination.
Some or all of the salt will dissolve into the water. This depends on the temperature of the water, and the presence of any other solutes in the water.
The presence or absence of spacecraft near Mars will have no effect whatsoever on the planet's gravitational field.
