Elemental bromine is a fuming red-brown liquid at room temperature, corrosive and toxic, with properties between those of chlorine and iodine.he diatomic element Br 2 does not occur naturally. Instead, bromine exists exclusively as bromide salts in diffuse amounts in crustal rock. Owing to leaching, bromide salts have accumulated in sea water at 65 parts per million (ppm), which is less than chloride.
As always, follow proper cooking instructions when preparing any meat to kill any potentially harmful bacteria. As long as you have your refrigerator at a reasonable temperature, your roast beef should be fine through the weekend at least. There's no reason you can't serve it hot if you want. Reheat it with some broth or just slice it and have it cold on a salad or in a sandwich.
Any kind of fresh meat in the fridge should be eaten within a week, and any meat that is unrefrigerated should be eaten within a day or a few hours, especially if itâs chicken. Raw beef and steaks are best at about three to four days in the fridge, but they can last up to six if you need them to.resh pork can last about as long as beef, but five days is the max. The USDA says to eat fresh pork within two days if itâs been sitting in the fridge, or freeze it within five days to prevent a buildup of bacteria.
