Final answer:
To calculate the number of joules released in the reaction, we need to know the enthalpy change (ΔH) of the reaction. Without that information, we cannot determine the exact number of joules released or its effect on the value of x1.
Step-by-step explanation:
To calculate the number of joules released in the reaction, we need to know the enthalpy change of the reaction (ΔH). The formula to calculate the heat released (q) is q = m * ΔH, where m is the mass of the substance and ΔH is the enthalpy change. However, the enthalpy change of the reaction between NaOH and another substance is needed to calculate the number of joules released. Without that information, we cannot determine the exact number of joules released or its effect on the value of x1.
