Calorimetry Worksheet 2 Answers Chemsheets _best_ -

When 0.5 g of magnesium is added to 100 mL of 1 M HCl, the temperature of the solution increases from 22.0°C to 28.0°C. Calculate the enthalpy change for the reaction.

If you need the exact Chemsheets answers with teacher notes:

A 50.0 g sample of an unknown metal is heated to 100.0°C and then placed into a calorimeter containing 100.0 g of water at 22.0°C. The final temperature of the water and metal is 25.0°C. What is the specific heat of the metal? (Specific heat of water = 4.18 J/g°C).

If you burn 0.20 g of fuel, don’t use 0.20 g as “m” in q=mcΔT—that mass is for the , not the fuel. calorimetry worksheet 2 answers chemsheets
