What is the metal part of a lamp surrounding the bulb and supporting the shade called?
If you mean the screw on part that holds the lamp shade on the it's called a Finial. If you mean the stand that hooks on right below the socket I've heard it called a harp.
Is selenium hard or soft?
If you mean the elements in their normal forms, F and Cl are gases, Br is a liquid, I is a solid. If you mean their ligand hard/soft qualities as halide ions:- the lighter ones are hard, Br- and I- soft
What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
100% RH
Is cabone a metal or non metal?
If you mean carbon, then it is a nonmetal.
Do 100-watt light bulb use energy 4 times as fast as does a 25-watt bulb?

What do you mean like did he invent the light bulb because if you do mean that then yes he did invent the light bulb
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
What does the spanish word wolframio mean in English?
It means "tungsten" -- the metal most associated with light bulb filaments. Its Latin name is wolfram, from which it gets its element symbol, which is W.
How does a metal halide lamp work?
A halogen lamp a uses a tungsten filament, but it is encased inside a much smaller quartz envelope. Because the envelope is so close to the filament, it would melt if it were maA halogen lamp also uses a tungsten filament, but it is encased inside a much smaller quartz envelope. Because the envelope is so close to the filament, it would melt if it were made from glass. The gas inside the envelope is also different -- it consists of a gas from the halogen group. These gases have a very interesting property: They combine with tungsten vapor. If the temperature is high enough, the halogen gas will combine with tungsten atoms as they evaporate and redeposit them on the filament. This recycling process lets the filament last a lot longer. In addition, it is now possible to run the filament hotter, meaning you get more light per unit of energy. You still get a lot of heat, though; and because the quartz envelope is so close to the filament, it is extremely hot compared to a normal light bulb. de from glass.
