SOLVED: During an experiment, a student adds 0.601 g of calcium metal to 150.0 mL of 65 M HCl. The student observes a temperature increase of 13.0 °C for the solution. Assuming the solution's final volume is 150.0 mL, the density is 1.00 g/mL, and the specific heat is 0.184 J/g·°C, calculate the heat of the reaction, ΔHrxn:Ca(s) 2HCl(aq) → CaCl2(aq) H2(g)NumberΔH543.015kJ/mol

Thank God we have calcium! Its compounds have a wide variety of applications. For example, calcium chloride (CaCl₂) is used in ice removal and dust control on dirt roads, as a conditioner for concrete, as an additive in canned tomatoes, and even to provide body for automobile tires.
