Definition of the Joule symbol J

Is the SI issued unit for energy, work and heat that is used in honour of James Prescott Joule (1818-1889)

General steps to calculate heat of reactions (1)

Determine the number of moles of the reactants and products formed, n mole

General steps to calculate heat of reactions (2)

Calculate the heat change in the reaction: Q = mcθ θ = change in temperature

General steps to calculate heat of reactions (3)

Calculate the heat change for 1 mole of reactant or 1 mole of product formed in proportion

General steps to calculate heat of reactions (4)

State the heat of reaction, ∆H with +/- signs and the correct units: ∆H = +/-X kJ mol−1

Number of moles, n represents (1)

Mole of precipitate formed for heat of precipitation

Number of moles, n represents (2)
