WebQuestion: In a Styrofoam cup calorimeter, 0.0500 mol of HCl is reacted with 0.0500 mol of NaOH in 50.0 mL of water. After the reaction is completed, the temperature of the water has increased by 13.7 °C. Calculate the molar heat of neutralization (ΔH in kJ/mol) for the following reaction: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) Assume that the specific …
WebSince the solution is aqueous, we can proceed as if it were water in terms of its specific heat and mass values. The density of water is approximately 1.0 g/mL, so 100.0 mL has a mass of about 1.0 × × 10 2 g (two significant figures). The specific heat of water is approximately 4.184 J/g °C, so we use that for the specific heat of the solution. bitmain official siteWebJan 27, 2006 · Note that temperature, in units of degrees Celsius (°C) or Kelvin (K), is a measure of how hot or cold a substance is, while heat, in units of joules (J) or calories (cal), is a measure of its thermal energy. … bitmain official websiteWebStyrofoam is a material that is made of expanded polystyrene foam (EPS).
