Question

200 mL of 0.2 M HCl is mixed with 300 mL of 0.1 M NaOH. The molar heat of neutralization of this reaction is –57.1 kJ. The increase in temperature in °C of the system on mixing is x × 10 . The value of x is ________ . (Nearest integer) [Given: Specific heat of water = 4.18 J g K Density of water = 1.00 g cm ] (Assume no volume change on mixing) : –2 –1 –1 –3
