That depends on the acidity of the water it is dissolved in. the higher the acid the more is lost.
The items baked lose their properties and become whole new substances with different properties. Also, the change cannot be reversed. (You can't "unbake" something!)
you lose it all
Yes
magnets ca lose their properties due to heating, repeated hitting, or through poor storage
Materials lose their original properties when their spatial conditions change, provided their atomic configuration change.
Baking soda is alkaline, and when mixed with acidic ingredients, it reacts and releases bubbles of carbon dioxide. These bubbles, when trapped inside batter, help baked goods rise. Other uses: * Baking soda is used in devil's food cake because it turns the cocoa powder reddish brown. * Vegetables cooked in water mixed with baking soda don't lose as much color, though the baking soda makes them mushier and causes them to lose vitamin C. * Sprinkling baking soda on a grease or electrical fire will help extinguish it. * Placing an opened box in the refrigerator or freezer will absorb bad odors * Baking soda is a good, mildly abrasive scouring powder.
Alkali and alkaline earth metals. Cations.
Alkali metals
Yes it can, it has an experation date on the container.
Magnets can lose their magnetic properties if exposed to high heat or are made subject to high impact. The temperature at which magnets lose magnetic properties is referred to as the Curie Temperature for ferromagnetic materials.
No because something
the basic properties of an electric charge is that they posses but negative and positive charge when they gain and lose electron.
