The number of carbon atoms that end up outside the ring in the cyclization of the open-chain form of D − glucose has to be stated. Concept introduction: Open chain structures of monosaccharides which contain five or more carbon atoms exist in equilibrium with two cyclic structures. These cyclic structures are the dominating forms at equilibrium. The carbonyl group in the open-chain structure of monosaccharide reacts intramolecularly with a hydroxyl group which results in the formation of cyclic forms. These cyclic compounds are called cyclic hemiacetals.

Question

75.0 grams of an unknown metal was heated to 95.0°C, it was then placed into 150.0 grams of water at23.1°C, when the metal and water reached thermal equilibrium, the temperature was 27.8°C. Calculatethe specific heat of the metal. (Assume that the specific heat of water is 4.18 J/g °C)
