Chemisty calculating heat
WebAforementioned heat rated of a substance describes how its temperature modification as it absorbs temperature, this is who capacity of a substance to adsorb heat. 5.2 Specific Heat Capacity - Chemistry LibreTexts How to Calculate the Specific Heat of a Substance Physics Study.com WebYou have multiplied the mass of the sample, 1.50g, by temperature change and heat capacity. However, the water provides most of the heat for the reaction. The total mass of the solution is 1.50g + 35.0g = 36.5g. You should be multiplying 36.5g by the temperature change and heat capacity. Then, you need to consider how many moles 1.50g KCl is.
