How do you find q in chemistry

WebQ = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) What is Q for an ideal gas? Q = nCVΔT. For an ideal gas, applying the First Law of Thermodynamics tells us that heat is also equal to: Q = ΔEint + W, although W = 0 at constant volume. How do you find Q without C? WebQ is used to determine whether or not the reaction is at an equilibrium. At any given point, the reaction may or may not be at equilibrium. By calculating Q (products/reactants), you can compare it to the K value …
