Does Hexane react with Bromine in the absence of ultraviolet light of intense heating?
Wiki User
∙ 16y ago
the solution turns red and splits into two colours, red on top and yellow on bottom; after standing the top (red) layer turns colourless and opaque but there is no real reaction.

What wavelength ultraviolet light is best for viewing fluorescent minerals?
Short-wave ultraviolet light (UV-C, 100-280 nm) is best for viewing fluorescent minerals, as it provides the most intense fluorescence. Medium-wave ultraviolet light (UV-B, 280-315 nm) can also be used, but the fluorescence will be less intense. Long-wave ultraviolet light (UV-A, 315-400 nm) is not ideal for viewing fluorescent minerals as it may not excite the fluorescence as effectively.
What is a blue flame used for on a bunson burner?
A blue flame on a Bunsen burner is used for heating applications that require a high temperature and clean combustion, such as sterilizing, heating chemicals, or performing lab experiments that require intense heat.
Which energy releasing process does not require oxygen?
Anaerobic respiration is an energy-releasing process that does not require oxygen. This process occurs in the absence of oxygen and can be found in certain microorganisms, as well as in muscle cells during intense exercise.
What is the source of latic acid?
Lactic acid is primarily produced during intense physical activity when the body breaks down glucose for energy in the absence of sufficient oxygen. It is also produced in small amounts as a byproduct of normal metabolism in the body.
Which materials are absent when coal is formed?
When coal is formed, plant matter such as dead trees, leaves, and other vegetation is present. However, there is an absence of oxygen, intense pressure, and heat are crucial factors during the coal formation process.
What type of light is hazardous and intense in welding?
Electric arc welding produces intense ultraviolet light, which is very hazardous to eyes and skin.
Which wave diagram best represents a dim red sunset on the right side to the light from an intense ultraviolet bug light on the left side?
A wave diagram with a longer wavelength on the right side corresponding to the dim red sunset and a shorter wavelength on the left side for the intense ultraviolet bug light would best represent the scenario. The red light has a longer wavelength than the ultraviolet light.
Can light destroy everything?
Light itself cannot necessarily destroy everything, but intense sources of light such as lasers can be focused to cause damage to certain materials by heating them. High-energy light, like ultraviolet and X-rays, can also be harmful to living cells and tissues, causing damage.

Long-wave ultraviolet light (UV-A, 315-400 nm) is not ideal for viewing fluorescent minerals as it may not excite the fluorescence as effectively.
Where light is not intense?
In areas where light is not intense, such as underground caves or deep underwater, organisms have adapted to low light levels through specialized features like bioluminescence or enhanced sensitivity to light. These environments select for organisms with unique survival strategies to thrive in the absence of intense light.
Why are the astronaut suits insulated?
Space is cold!Sunlight is very intense in space, causing rapid heating of exposed surfaces. Spacesuits are white to reduce this solar heating effect, but it doesn't eliminate it.
The hot Gas in Star Formation Regions emits light because of?
The hot gas in star formation regions emits light due to the intense heating caused by compression and gravitational collapse. This heating excites the gas molecules and causes them to emit radiation across the electromagnetic spectrum, from infrared to ultraviolet. This light is what we observe as the glowing nebulae in star formation regions.
Can the tectonic plates move rapidly?
They cant unless there was some random intense heating of the entire planet. As tectonic plates move because of the heating by the lava the lava would have to heat up intensely.
What does uv relate to?
It's related to the notification or alerting about a particular area that the amount of ultraviolet radiation reaching is expected to be unusually intense compared to historical levels in that area .
Does Mercury have UV radiation?
Yes, Mercury does receive high levels of ultraviolet radiation from the Sun. Its thin atmosphere provides limited protection from these harmful rays, making the surface a harsh environment with intense UV exposure.
What does uv alert relate to?
It's related to the notification or alerting about a particular area that the amount of ultraviolet radiation reaching is expected to be unusually intense compared to historical levels in that area .
Does infrared radiation cause burns?
Yes, prolonged exposure to infrared radiation can cause burns. Infrared radiation can penetrate the skin and heat tissues beneath the skin surface, resulting in burns similar to those caused by exposure to heat sources like fire or hot objects.
