If the result after calculating the heat of the calorimeter is negative, what conclusion can you make?

It means that the signs of the temperatures are calculated wrong

When the mass of substance is multiplied with the specific heat, the product is equal to heat capacity, which is donated as \(C\) and can be seen on the calorimeter. Heat capacity, C, can never be negative for a mass or a substance and the specific heat of a substance can never be negative. So if it is negative it means that the calculations went wrong.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
