Please help due tonight!!! Any links WILL BE FLAGGED. When 57,816 J of heat are transferred to a 240-g of an unknown metal, its temperature increases from 32⁰C to 164⁰ C. Identify the metal.

The correct answer is b.hoped i you

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

The image seems to be behind the mirror, but nothing is really there.just took the test.

The answers to this question are as following: -increase the sample size from 6 cups to 12 cups of sand and water.-use more precise digital thermometers-use more precise scales that measure to the hundredth of a gram
