The reaction of magnesium oxide with hydrochloric acid carried out in a calorimeter caused the temperature of water to change from 25.0°C to 46.0°C. In this reaction, 4860 J of energy was released. What mass of water was present?
Added by Tamara J.
Step 1
We know that the temperature of the water changed from 25.0°C to 46.0°C, so the change in temperature is: ΔT = 46.0°C - 25.0°C = 21.0°C We also know that 4860J of energy was released in the reaction. This energy is absorbed by the water, so: q = 4860J Now, we Show more…

When a 5.83 g sample of magnesium metal is burned, it produces enough heat to raise the temperature of 1,154 g of water from 24.00 °C to 33.10 °C. How much heat did the magnesium release when it burned? (The specific heat of water is 4.184 J/g °C)

A 1.326 g sample of magnesium was burned in an oxygen bomb calorimeter. The total heat capacity of the calorimeter plus water was 5,760 J/°C. If the temperature rise of the calorimeter with water was 0.570°C, calculate the enthalpy of combustion of magnesium. Mg(s) + 1/2O2(g) → MgO(s).
