A sample of an unknown metal has a mass of 120.4 g. As the sample cools from 90.5°C to 25.7°C, it releases 7020 J of energy. Usinf the chart below, what is the identity of the metal in the sample? Hint Calculate specific heat first Substance Specific Heat Water (liquid) 4.184 J/g °C 0.899 J/g °C 0.803 J/g °C 0.449 J/g °C a) Aluminum ) b) Granite Oc) Water d) Iron​

Explanation:

There’s no picture >>>>>

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

diaria maybe go see a doctor about that
