Calculate the amount of heat energy required to melt 550.0 grams of copper, already at its melting point. NEED ASAP​

18,300 J

Explanation:

In order to be able to answer this question, you must know the value of water's enthalpy of fusion,  

, which is listed as

ΔH↔ = 18,300J

Now, a substance's enthalpy of fusion tells you how much heat is needed in order to convert   of said substance from solid at its melting point to liquid at its melting point.

In water's case, an enthalpy of fusion equal to  

333.55 J g

333.55 J

of heat.

Your ice cube has a mass of  

55.0 g

law of conservation of matter

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.
