Yes and no. European appliances run off 220V whereas American appliances run at 110V. However, American homes are wired for both 220 and 110 volts. 220 is just only used for large loads like ovens and dryers. If you know what you are doing you can install 220V outlets and then no, you don't need voltage converters. However, this is a very big job and is not worth the expense if you only have a few European appliances. You can buy 110-220V converters for this purpose.
Quite honestly, there is no specific gas. Granted there are some chemical reactions that would create gases with halogens and H2O, but since you're being very vague on the specific halogen, I can't provide a specific answer. Not all halogens have large reactions with water. In fact, the government forces the American water supply to contain Fluorine (a halogen) to improve the dental health of the country.
In some specific circumstances, hydrogen can behave partly as an alkaline metal as well as a halogen element. This is due to the similarity of the two groups.
Any element, other than a halogen is - by definition - not a halogen and so it does not have a halogen and that is less than one halogen.
Potassium is a metal element. It is not a halogen. Example for halogen is Chlorine.
Yes, I (iodine) is a halogen.
A halogen is a gas, such as iodine or bromine. Halogen bulbs contain a small amount of halogen gas. For more information, see the related links, below.
This halogen is astatine.
Yes, bromine is a halogen.
No, Bromine is a Halogen
It is a halogen
Halogen gas is in a Tungsten-Halogen Light Bulb.
Selenium is a Halogen
This halogen is iodine (I).
Gold is not a halogen it is a transition metal
Halogen is a gas, so your question doesn't make much sense. If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
Carboxyl grouped compound cant be called halogen compound if it dont have halogen element. Halogen elements are F, Cl, Br, I. In hydrocarbon one H is replaced with halogen element.
The halogen found in seawater is bromine.
Chlorine is the most important halogen.
Bromine is the only liquid halogen
The lightest halogen would be fluorine.
Halogen - band - was created in 1998.
Halogen TV was created in 2009.
Astatine is the 6th period halogen.
