75.0 grams of unknown metal was heated to 95.0 ºC. It was then placed into 150 grams of water at 23.1 ºC. When the metal and water reached thermal equilibrium, the temperature was 27.8 ºC. Calculate the specific heat of the metal.

b) mutualism

hope this : )

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
