1/1/1997· Fluorine is a pale yellow gas which condenses to a canary yellow liquid, bp −188.1 C (intermediate between N 2, bp −195.8 , and O 2, bp −183.0 C). Chlorine is a greenish-yellow gas, bp −34.0°, and bromine a dark-red mobile liquid, bp 59.5°: interestingly the colour of both elements diminishes with decrease in temperature and at −195° Cl 2 is almost colourless and Br 2 pale yellow.

flask was hermetically sealed with a stopper and put into a water bath placed on a hot plate-stirrer. During the extraction, the sample solution was stirred constantly. After 15min of extraction, the stirrer was turned off and after a 1-min wait, a 1µl aliquot of the

Fluorine gas is placed in contact with calcium metal at …

Explanation: When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride. Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet. Therefore, the chemical reaction equation will be as follows.

Fluorine gas is placed in contact with calcium metal at …

Explanation: We are given fluorine gas which is held in contact with the calcium metal and produces calcium fluoride. The balanced chemical equation for this reaction is : 1 mole of Calcium metal reacts with 1 mole of Fluorine molecule to produces 1 mole of Calcium fluoride.
