Please answer question 2 Question 1How does dishwashing detergent lower the surface tension of water?The detergent disrupts the hydrogen bonding network of the water at thesurface and reduces the surface tension of waterIt is unknownThe Na+ cation of detergent exchanges with H+ cation of water. This causes thesurface tension to decreaseDetergent chemically reacts with water. The resulting water/detergent producthas a lower surface tensionQuestion 2You heat a 54.2 g sample of hexanes using a heater using 223.3 W of power for 10.0seconds. If the initial temperature is 21.1 °C what is the final temperature in °C ? Weexpect your response to have the correct number of significant figures with correctrounding. You can assume there is no heat loss in the conversion from electricity toheat.

Given that: mass of sample = 54.2 g Power = 223.3 W Time = 10.0 s Initial temperature = 21.1 oC To…
