What type of organic compounds show UV absorption bands?
Aromatic compounds, conjugated dienes, and compounds with extensive pi-electron systems often show UV absorption bands. These compounds have delocalized electrons that can undergo electronic transitions when exposed to ultraviolet light, leading to absorption of UV radiation.
What change in color is observed when silver chloride is left exposed to sunlight. What type of chemical reaction is this?
This is a photochemical reaction of decomposition: silver (black) is released.
Are actinide and lanthanide series is transition metals?
Actinides are all soft and silver in color (but not when exposed to air). They are dense and malleable. Most actinides have the same properties as the d-block.
What is the part of a soil profile that is made up of partly weathered rock?
Regolith is mostly a product of weathering. Bedrock may be exposed to water or other compounds that percolate through the soil, or it may occur as an outcrop.
What was John Needham's Experiment?
John Needham,s (1713-1781) experimenting with meat exposed to hot ashes observed the apperaincing of organisms not peresent at the start of the experiment and concluded that the bacteria orignite form the meatITS EXPERIMENT WAS FALSE
What is observed when copper sulphatepentahydrate is exposed to ammonia gas?
A chemical reaction is observed.
What type of organic compounds show UV absorption bands?
Aromatic compounds, conjugated dienes, and compounds with extensive pi-electron systems often show UV absorption bands. These compounds have delocalized electrons that can undergo electronic transitions when exposed to ultraviolet light, leading to absorption of UV radiation.
What part of the skin is observed in an annual physical?
The exposed areas of the skin are observed; the size and shape of any lesions are noted
What transition metal rusts when exposed to oxygen?
Iron rusts in the presence of Oxygen.
What are the effects of a electronic device exposed to magnets?
electronic devices that get too close to magnets, can stop working properly.
How many hours of electronic media are children exposed to in a day?
3
What change in colour is observed when a silver chloride is left exposed to sunlight?
The colour will change into grey.
Does water damage router?
Definitely, electronic devices should never be exposed to water!
A type of pollution that forms when nitrogen and carbon compounds are exposed to sunlight is called?
photochemical smog
Does light emmitting diode technology use organic compounds that produce light when exposed to exlectric current?
true
What would happen to your skin if exposed to substances at the extremes of the pH scale?
burning melting blistering of the skin where the compounds hit.
What are photovoltaic compounds?
Photovoltaic compounds are compounds that transfer electrons in a circuit when exposed to light. Light (which is a type of electromagnetic radiation) transfers energy into the compound, which causes electrons to be rearranged. This rearrangement can be directed into a wire and results in electrical potential (voltage, electromotive force) that can be harnessed. These compounds form the basis of solar cell technology.
