Answer:Metals are mostly used in the alloy form like steel that is anticorrosive. Food cooked in earthy metal utensils is healthier than by plastic utensils. They do not react or change form while cooking to leave any trace particles on the surface . Food odors are not retained by metal cookware unlike the plastic ware
Explanation:
The kind of reaction that is likely to be observed is a single displacement reaction where the metal displaces the H+ ion from the acid. The general chemical reaction would be written as 2M + 2HX = 2MX + H2 where M represents a metal and HX is the acid.
You can never say that any substance is a liquid, a solid, or a gas. Every substance you name can be all of those, depending on the TEMPERATURE.
At standard pressure . . .
-- Iodine is solid below 113.7°C, and gas above 184°C .
-- Bromine is solid below -7.2°C, and gas above 58.8°C .
-- "Room temperature" is considered to be the range from 20°C to 23.5°C.
-- Iodine is solid in that range.
-- Bromine one of only two elements that are known to be liquids AT
ROOM TEMPERATURE. The other one is mercury ... a metal.
