Reacting masses chemistry

WebReacting masses. The masses of reactants are useful to determine how much of the reactants exactly react with each other to prevent waste. This equation shows the ratio of … Webq = mcΔT. In this equation: q is the enthalpy change of the reaction, measured in J. m is the mass of X, measured in g. c is the specific heat capacity of X, measured in J g -1 K -1. ΔT is the temperature change of X, measured in K. Specific heat capacity, c, is the energy needed to raise the temperature of one gram of a substance by one kelvin.
